Stop Fixing Legacy Java: The AI That Does It For You

1
00:00:00,000 --> 00:00:03,880
Still hand upgrading legacy Java, that's not craftsmanship, that's unpaid penance.

2
00:00:03,880 --> 00:00:07,880
Manual modernization is a failure mode, slow, error prone and permanently behind.

3
00:00:07,880 --> 00:00:08,880
The truth?

4
00:00:08,880 --> 00:00:12,280
AI agents now handle the drudgery with receipts.

5
00:00:12,280 --> 00:00:13,520
Here's what you actually get.

6
00:00:13,520 --> 00:00:17,120
Time back, CV is gone, and cloud bills that stop bleeding.

7
00:00:17,120 --> 00:00:18,760
We'll walk a narrative case study.

8
00:00:18,760 --> 00:00:23,200
Stack, benchmarks, results, plus a full audit trail so governance can breathe.

9
00:00:23,200 --> 00:00:26,000
There's one metric that embarrassed finance and delighted security.

10
00:00:26,000 --> 00:00:26,880
Stay for that.

11
00:00:26,880 --> 00:00:30,640
Now, here's what happens when you let co-pilot app modernization drive.

12
00:00:30,640 --> 00:00:33,840
Case set up, the legacy stack and the modernization mandate.

13
00:00:33,840 --> 00:00:37,800
Baseline first, we're dealing with a Java 8-era spring application,

14
00:00:37,800 --> 00:00:40,800
classic MVC plus a sprinkle of scheduled jobs,

15
00:00:40,800 --> 00:00:43,440
built with maven, running on AWS.

16
00:00:43,440 --> 00:00:47,080
Conservative governance, noisy alerts, everyone swears the app is stable

17
00:00:47,080 --> 00:00:48,800
while pager duty begs to differ.

18
00:00:48,800 --> 00:00:51,720
The stack has drift, parent-poms forked years ago,

19
00:00:51,720 --> 00:00:54,280
dependency versions pinned like insect specimens,

20
00:00:54,280 --> 00:00:57,040
and a CI pipeline that only passes if you chant.

21
00:00:57,040 --> 00:00:59,920
Average user behavior, ignore the red badges,

22
00:00:59,920 --> 00:01:03,960
silence the scanner, and pray the next sprint includes tech debt.

23
00:01:03,960 --> 00:01:05,800
Spoiler, it never does.

24
00:01:05,800 --> 00:01:07,200
Pain inventory.

25
00:01:07,200 --> 00:01:10,960
Version drift means modern libraries won't resolve without exclusions,

26
00:01:10,960 --> 00:01:13,320
dependency hell, transitive roulette,

27
00:01:13,320 --> 00:01:16,920
where one logging upgrade detonates your HTTP client.

28
00:01:16,920 --> 00:01:20,280
Unpatched CVEs sit there politely waiting for an exploit kit,

29
00:01:20,280 --> 00:01:23,080
idle compute waste, auto scaling that never scales down,

30
00:01:23,080 --> 00:01:26,760
instances at 8% CPU while finance funds a space heater.

31
00:01:26,760 --> 00:01:30,360
Add brittle configs, environment variables baked into user data,

32
00:01:30,360 --> 00:01:32,880
stateful file rights on disk and secrets living

33
00:01:32,880 --> 00:01:34,120
where secrets shouldn't live.

34
00:01:34,120 --> 00:01:35,040
Constraint?

35
00:01:35,040 --> 00:01:38,320
This is audio only, no performative heroics, no live tabs,

36
00:01:38,320 --> 00:01:40,120
switching to stack overflow.

37
00:01:40,120 --> 00:01:42,040
We rely on reproducible artifacts, reports,

38
00:01:42,040 --> 00:01:45,360
commitments, scanner outputs, because guesswork is not a strategy

39
00:01:45,360 --> 00:01:47,480
and worked on my laptop isn't evidence.

40
00:01:47,480 --> 00:01:48,920
Why Java? 21.

41
00:01:48,920 --> 00:01:51,400
Virtual threats change concurrency from a scarce resource

42
00:01:51,400 --> 00:01:52,600
to a commodity.

43
00:01:52,600 --> 00:01:55,320
Thousands of lightweight threads with minimal overhead,

44
00:01:55,320 --> 00:01:57,960
throughput goes up, tail latency comes down.

45
00:01:57,960 --> 00:02:00,800
garbage collection improvements, G1 and ZGC refinements

46
00:02:00,800 --> 00:02:02,320
reduce pause times.

47
00:02:02,320 --> 00:02:04,640
The foreign function and memory API is stable,

48
00:02:04,640 --> 00:02:06,680
which matters if you're calling native code

49
00:02:06,680 --> 00:02:08,640
or wrestling with off heap buffers.

50
00:02:08,640 --> 00:02:11,560
Net effect, measurable performance and maintainability gains.

51
00:02:11,560 --> 00:02:13,320
Most people think upgrading is cosmetic.

52
00:02:13,320 --> 00:02:14,080
Incorrect.

53
00:02:14,080 --> 00:02:16,400
You get cheaper concurrency and fewer stalls,

54
00:02:16,400 --> 00:02:18,840
directly visible in service level graphs.

55
00:02:18,840 --> 00:02:21,480
Migrationscope, AWS out, Azure in,

56
00:02:21,480 --> 00:02:23,600
align with enterprise standards, consolidate billing

57
00:02:23,600 --> 00:02:25,760
and plug into the platform, your identity policy

58
00:02:25,760 --> 00:02:27,760
and observability already inhabit.

59
00:02:27,760 --> 00:02:30,280
We'll target Azure app service or Azure Spring apps

60
00:02:30,280 --> 00:02:32,120
depending on the workload profile.

61
00:02:32,120 --> 00:02:34,480
Simple app app service is fine.

62
00:02:34,480 --> 00:02:37,040
Spring heavy microservices with scaling nuance,

63
00:02:37,040 --> 00:02:38,920
consider Azure Spring apps.

64
00:02:38,920 --> 00:02:41,680
For data, the mandate is Azure SQL database.

65
00:02:41,680 --> 00:02:43,600
Yes, you can keep post-gress cool on Azure,

66
00:02:43,600 --> 00:02:45,120
but the business wants consolidation,

67
00:02:45,120 --> 00:02:47,440
so we'll map the path and show the trade-offs.

68
00:02:47,440 --> 00:02:49,080
Governance stands.

69
00:02:49,080 --> 00:02:51,520
Every action lands in Git.

70
00:02:51,520 --> 00:02:53,840
Differable, reversible, attributable.

71
00:02:53,840 --> 00:02:57,440
The agent generates a plan, opens issues and proposes commits.

72
00:02:57,440 --> 00:03:00,360
You approve, it resolves builds, patches dependencies

73
00:03:00,360 --> 00:03:03,320
applies code transformations, using known recipes,

74
00:03:03,320 --> 00:03:06,280
regenerates the s-bomb and reruns scanners.

75
00:03:06,280 --> 00:03:09,960
If something doesn't pass, it loops no alt-tap pilgrimage.

76
00:03:09,960 --> 00:03:12,800
And when it can't proceed, it asks for input and documents why.

77
00:03:12,800 --> 00:03:13,760
See the difference?

78
00:03:13,760 --> 00:03:16,040
Work becomes auditable instead of anecdotal.

79
00:03:16,040 --> 00:03:18,880
Before you let an agent touch anything, you assess.

80
00:03:18,880 --> 00:03:21,680
Automated inventory across modules, dependencies,

81
00:03:21,680 --> 00:03:24,200
build plugins and runtime configs.

82
00:03:24,200 --> 00:03:27,920
Risk ranked findings with references to advisories and documentation.

83
00:03:27,920 --> 00:03:30,080
Cloud readiness flags for service bindings,

84
00:03:30,080 --> 00:03:32,200
environment variables and stateful traps

85
00:03:32,200 --> 00:03:34,120
that break when containers come and go.

86
00:03:34,120 --> 00:03:36,600
Cospace lines, compute hours, idle percentages,

87
00:03:36,600 --> 00:03:39,080
and the egress patterns that finance pretends not to notice

88
00:03:39,080 --> 00:03:39,960
until month end.

89
00:03:39,960 --> 00:03:42,520
You might be thinking, we can triage that by hand.

90
00:03:42,520 --> 00:03:43,360
Fascinating.

91
00:03:43,360 --> 00:03:45,280
And you're still surprised the app crashes.

92
00:03:45,280 --> 00:03:47,560
The average user misses the long tail issues,

93
00:03:47,560 --> 00:03:50,400
deprecated APIs deep in the scheduler, a logging bridge,

94
00:03:50,400 --> 00:03:54,520
masking duplicate class conflicts, or that one library pin

95
00:03:54,520 --> 00:03:56,320
that blocks everything from moving.

96
00:03:56,320 --> 00:03:58,520
The agent doesn't miss them because it doesn't get bored.

97
00:03:58,520 --> 00:04:01,400
So the modernization mandate is simple and final.

98
00:04:01,400 --> 00:04:04,600
Upgrade to Java 21, eliminate CVEs, container-wise,

99
00:04:04,600 --> 00:04:07,760
migrate to Azure Wire CI/CD with control drawouts

100
00:04:07,760 --> 00:04:10,360
and force policy via approvals and key vault,

101
00:04:10,360 --> 00:04:13,040
and cut cost without cutting reliability.

102
00:04:13,040 --> 00:04:15,760
All changes trace back to commits with rationale.

103
00:04:15,760 --> 00:04:20,160
No black box, no swaggering hero commits a 2AM assessment first

104
00:04:20,160 --> 00:04:21,920
because guesswork is not a strategy.

105
00:04:21,920 --> 00:04:23,200
Then we execute.

106
00:04:23,200 --> 00:04:24,040
Assessment.

107
00:04:24,040 --> 00:04:26,760
The AI exposes technical debt with receipts.

108
00:04:26,760 --> 00:04:29,040
Here's what actually happens when you press assess.

109
00:04:29,040 --> 00:04:30,400
The agent doesn't scan.

110
00:04:30,400 --> 00:04:31,360
It inventories.

111
00:04:31,360 --> 00:04:33,800
Code, build files, plugins,

112
00:04:33,800 --> 00:04:35,360
transitive dependencies,

113
00:04:35,360 --> 00:04:37,600
Docker Bits, environment variables,

114
00:04:37,600 --> 00:04:39,760
start-up scripts, even though stray shell wrapper

115
00:04:39,760 --> 00:04:42,400
someone copy-pasted in 2017.

116
00:04:42,400 --> 00:04:43,840
It builds a dependency graph

117
00:04:43,840 --> 00:04:46,200
annotates it with CVE data and ranks risk.

118
00:04:46,200 --> 00:04:50,200
Not vibes, severity, exploitability, reachability.

119
00:04:50,200 --> 00:04:53,040
It's the Windows registry of your app's reality.

120
00:04:53,040 --> 00:04:55,640
Not just a list, your structural spine exposed.

121
00:04:55,640 --> 00:04:56,440
The truth?

122
00:04:56,440 --> 00:04:58,360
Most people think they know their stack.

123
00:04:58,360 --> 00:04:58,880
They don't.

124
00:04:58,880 --> 00:05:00,640
The agent finds the forked parent pom

125
00:05:00,640 --> 00:05:03,280
with a logging version pin that blocks every downstream patch.

126
00:05:03,280 --> 00:05:05,640
It flags duplicated SLF4J bridges

127
00:05:05,640 --> 00:05:07,480
that shadow each other like feuding roommates.

128
00:05:07,480 --> 00:05:09,440
It catches the servlet container

129
00:05:09,440 --> 00:05:11,240
that's quietly three releases behind

130
00:05:11,240 --> 00:05:13,280
because your CI only tests the happy path.

131
00:05:13,280 --> 00:05:15,520
And yes, it maps deprecated APIs

132
00:05:15,520 --> 00:05:16,640
you've been calling for years

133
00:05:16,640 --> 00:05:18,880
because nobody wanted to touch the job scheduler.

134
00:05:18,880 --> 00:05:20,480
Spoiler alert, you're touching it now.

135
00:05:20,480 --> 00:05:22,280
CVE is next, severity breakdown,

136
00:05:22,280 --> 00:05:24,360
affected libraries and references to advisories,

137
00:05:24,360 --> 00:05:25,760
direct links, not rumors.

138
00:05:25,760 --> 00:05:27,360
Critical and high get top billing,

139
00:05:27,360 --> 00:05:30,080
but it also identifies whether the vulnerable code paths

140
00:05:30,080 --> 00:05:31,400
are reachable by your application.

141
00:05:31,400 --> 00:05:32,920
Reachability matters.

142
00:05:32,920 --> 00:05:34,760
If a transitive library has an issue

143
00:05:34,760 --> 00:05:37,160
but your code never calls the vulnerable class,

144
00:05:37,160 --> 00:05:38,440
it's still flagged,

145
00:05:38,440 --> 00:05:41,880
but the agent prioritizes fixes that reduce real risk first.

146
00:05:41,880 --> 00:05:45,120
You get the remediation options, bump versions at exclusions

147
00:05:45,120 --> 00:05:46,680
or swap artifacts entirely.

148
00:05:46,680 --> 00:05:48,120
That's a menu, not a mystery.

149
00:05:48,120 --> 00:05:49,920
Upgrade readiness comes with receipts.

150
00:05:49,920 --> 00:05:53,400
Java 21 requires you to stop pretending it's 2009.

151
00:05:53,400 --> 00:05:54,920
The agent runs open rewrite recipes

152
00:05:54,920 --> 00:05:56,720
against your code base in dry run mode,

153
00:05:56,720 --> 00:05:58,880
showing exactly which APIs are deprecated,

154
00:05:58,880 --> 00:06:01,960
which imports must change and where behavior shifts lurk.

155
00:06:01,960 --> 00:06:03,800
It calls out illegal reflective access.

156
00:06:03,800 --> 00:06:08,080
JUC quirks and the tiny landmines waiting in XML configuration.

157
00:06:08,080 --> 00:06:09,600
It notes frameworks that are ready.

158
00:06:09,600 --> 00:06:11,480
Spring versions plug in compatibility

159
00:06:11,480 --> 00:06:14,040
and those that need coercion, no hand waving.

160
00:06:14,040 --> 00:06:17,120
Every proposed change links back to docs and migration notes.

161
00:06:17,120 --> 00:06:19,400
Cloud readiness is where your infrastructure signs

162
00:06:19,400 --> 00:06:20,720
go to be catalogued.

163
00:06:20,720 --> 00:06:22,600
The agent identifies stateful traps,

164
00:06:22,600 --> 00:06:25,040
writing temp files to local disk during requests,

165
00:06:25,040 --> 00:06:27,440
caching sessions in memory across instances,

166
00:06:27,440 --> 00:06:29,920
storing secrets in a text file under opt

167
00:06:29,920 --> 00:06:32,560
because someone needed it to work.

168
00:06:32,560 --> 00:06:34,480
It flags environment variable usage

169
00:06:34,480 --> 00:06:37,000
that assumes EC2 meta data patterns.

170
00:06:37,000 --> 00:06:39,040
It points out service bindings for radius cues

171
00:06:39,040 --> 00:06:41,400
and databases that won't survive container churn.

172
00:06:41,400 --> 00:06:43,880
Then it proposes bindings the as-you-away.

173
00:06:43,880 --> 00:06:45,760
Connection strings move to configuration,

174
00:06:45,760 --> 00:06:48,400
key vault for secrets, managed identities for hours.

175
00:06:48,400 --> 00:06:49,360
You know, like adults.

176
00:06:49,360 --> 00:06:50,600
Now the finance shocker.

177
00:06:50,600 --> 00:06:51,840
Cost base lines.

178
00:06:51,840 --> 00:06:54,200
The agent pulls compute hours, instant sizes,

179
00:06:54,200 --> 00:06:56,040
scale patterns and idle percentages

180
00:06:56,040 --> 00:06:58,080
from telemetry and infrared definitions.

181
00:06:58,080 --> 00:07:00,960
It estimates egress costs based on outbound patterns.

182
00:07:00,960 --> 00:07:02,440
Yes, that one noisy batch job

183
00:07:02,440 --> 00:07:05,920
that hurls data across regions every night gets a line item.

184
00:07:05,920 --> 00:07:08,200
It translates all of this into a monthly number

185
00:07:08,200 --> 00:07:09,720
that doesn't care about your anecdotes.

186
00:07:09,720 --> 00:07:11,440
This is the number that embarrassed finance

187
00:07:11,440 --> 00:07:12,640
and delighted security.

188
00:07:12,640 --> 00:07:15,120
Why? Because eliminating CVEs while cutting spend

189
00:07:15,120 --> 00:07:17,200
is the only religion both teams share.

190
00:07:17,200 --> 00:07:18,840
Artifacts or it didn't happen.

191
00:07:18,840 --> 00:07:21,120
The agent produces a plan file with sections.

192
00:07:21,120 --> 00:07:24,240
CVE remediation steps, Java upgrade recipes,

193
00:07:24,240 --> 00:07:28,200
build changes, code transformations, containerization moves

194
00:07:28,200 --> 00:07:30,080
and cloud target mappings.

195
00:07:30,080 --> 00:07:33,040
It opens issues per work stream, tags owners if you want

196
00:07:33,040 --> 00:07:35,360
and scaffolds commits in a separate branch.

197
00:07:35,360 --> 00:07:38,080
Clean small difts with rationales in the messages.

198
00:07:38,080 --> 00:07:40,080
Espoo M generated signed and versioned.

199
00:07:40,080 --> 00:07:41,920
Von Rability scanner outputs attached.

200
00:07:41,920 --> 00:07:43,440
That's audit ready from step zero.

201
00:07:43,440 --> 00:07:45,240
You want traceability?

202
00:07:45,240 --> 00:07:47,880
Every finding links to an advisory or a source document.

203
00:07:47,880 --> 00:07:50,280
NVD entries, project release notes,

204
00:07:50,280 --> 00:07:53,680
open rewrite recipe documentation as your migration guides.

205
00:07:53,680 --> 00:07:55,120
When it suggests replacing a library,

206
00:07:55,120 --> 00:07:57,000
it cites compatibility matrices.

207
00:07:57,000 --> 00:07:58,800
When it recommends moving a secret,

208
00:07:58,800 --> 00:08:00,880
it points to platform guidance on key vault

209
00:08:00,880 --> 00:08:02,480
and managed identities.

210
00:08:02,480 --> 00:08:04,560
It's not just because AI said so,

211
00:08:04,560 --> 00:08:07,240
it's because this standard right here says so.

212
00:08:07,240 --> 00:08:08,560
Controls remain human.

213
00:08:08,560 --> 00:08:10,920
The plan sits in Git awaiting approval.

214
00:08:10,920 --> 00:08:14,200
You can adjust priorities, reject a remediation strategy

215
00:08:14,200 --> 00:08:15,920
or demand a different target service

216
00:08:15,920 --> 00:08:18,040
as your app service versus as your spring apps

217
00:08:18,040 --> 00:08:19,960
with the trade-offs listed plainly.

218
00:08:19,960 --> 00:08:22,800
The agent adapts, reruns the assessment delta

219
00:08:22,800 --> 00:08:25,200
and updates artifacts, no sulking.

220
00:08:25,200 --> 00:08:27,200
Once you see the receipts, the posture changes.

221
00:08:27,200 --> 00:08:30,040
You stop debating if modernization is worth it

222
00:08:30,040 --> 00:08:31,760
and start sequencing the work.

223
00:08:31,760 --> 00:08:35,000
And yes, the average user will still try to ship a feature first.

224
00:08:35,000 --> 00:08:35,800
Fascinating.

225
00:08:35,800 --> 00:08:38,200
Meanwhile, the agent has already mapped the shortest path

226
00:08:38,200 --> 00:08:40,360
to a secure, compliant, cheaper runtime,

227
00:08:40,360 --> 00:08:43,640
approve the plan, then what should do the work you keep postponing?

228
00:08:43,640 --> 00:08:47,680
Automated upgrade from Java 8 to Java 21 without the drama.

229
00:08:47,680 --> 00:08:50,840
Plan approved so the agent stops talking and starts doing.

230
00:08:50,840 --> 00:08:52,400
The loop is simple and merciless.

231
00:08:52,400 --> 00:08:56,040
Apply recipe, build, test, patch, repeat until green.

232
00:08:56,040 --> 00:08:58,840
No heroic tap explosion, no forum archeology,

233
00:08:58,840 --> 00:09:00,520
no tri-clean install.

234
00:09:00,520 --> 00:09:03,600
It uses open rewrite recipes to rewrite APIs,

235
00:09:03,600 --> 00:09:05,600
maven enforces to normalize versions

236
00:09:05,600 --> 00:09:07,800
and a unit integration test suite to prove

237
00:09:07,800 --> 00:09:09,440
it didn't break your world.

238
00:09:09,440 --> 00:09:11,040
When a build fails, it doesn't panic.

239
00:09:11,040 --> 00:09:13,880
It biceps the failure, proposes a targeted change

240
00:09:13,880 --> 00:09:16,320
and reruns, discipline at machine speed.

241
00:09:16,320 --> 00:09:19,320
Dependency upgrades are where humans usually create chaos.

242
00:09:19,320 --> 00:09:20,800
Enter bomb alignment.

243
00:09:20,800 --> 00:09:22,960
The agent adopts the official bill of materials

244
00:09:22,960 --> 00:09:26,200
for spring and related ecosystems, centralizes versions

245
00:09:26,200 --> 00:09:29,120
and kills the version sprinkling across child pumps.

246
00:09:29,120 --> 00:09:30,920
It tightens version ranges to exacts

247
00:09:30,920 --> 00:09:33,240
or manage constraints to prevent transitive roulette,

248
00:09:33,240 --> 00:09:34,680
removes redundant exclusions

249
00:09:34,680 --> 00:09:36,640
and adds the one exclusion that actually matters

250
00:09:36,640 --> 00:09:38,240
when two logging back ends dual.

251
00:09:38,240 --> 00:09:40,960
Result, fewer surprises, fewer conflicting jars,

252
00:09:40,960 --> 00:09:43,080
fewer midnight pages, you know, stability.

253
00:09:43,080 --> 00:09:46,880
Now the code, Java 21 means your old APIs need adult supervision.

254
00:09:46,880 --> 00:09:48,880
The agent replaces deprecated classes

255
00:09:48,880 --> 00:09:51,680
and methods with supported equivalents, updates, imports

256
00:09:51,680 --> 00:09:54,600
and adjusts method signatures where the platform evolved.

257
00:09:54,600 --> 00:09:58,080
It surfaces optional refactors, record and pattern usage,

258
00:09:58,080 --> 00:10:00,800
sequenced collections, behind a feature flag

259
00:10:00,800 --> 00:10:02,400
so the diff stays minimal.

260
00:10:02,400 --> 00:10:04,400
It also addresses illegal reflective access

261
00:10:04,400 --> 00:10:08,000
by swapping in supported SPI or JDK sanctioned alternatives

262
00:10:08,000 --> 00:10:10,200
then annotates the commit with a short rational

263
00:10:10,200 --> 00:10:11,840
and links to migration notes.

264
00:10:11,840 --> 00:10:13,800
It's not just a patch, it's evidence.

265
00:10:13,800 --> 00:10:16,360
Security remediation is not an afterthought bolted to the end.

266
00:10:16,360 --> 00:10:17,320
It's in line.

267
00:10:17,320 --> 00:10:19,840
As dependencies move the agent checks CVs again,

268
00:10:19,840 --> 00:10:22,040
closes the loop on any residual findings

269
00:10:22,040 --> 00:10:24,960
and regenerates the S-bomb so your scanners see the new world,

270
00:10:24,960 --> 00:10:26,120
not your memory of it.

271
00:10:26,120 --> 00:10:27,840
And yes, it runs the vulnerability scanner

272
00:10:27,840 --> 00:10:30,000
and fails the bill if something regresses.

273
00:10:30,000 --> 00:10:31,320
You call it strict.

274
00:10:31,320 --> 00:10:34,560
Correct, security calls it minimum viable professionalism.

275
00:10:34,560 --> 00:10:37,440
Let's talk tests because the average user loves to say,

276
00:10:37,440 --> 00:10:39,760
it compiles like that's an achievement.

277
00:10:39,760 --> 00:10:42,400
The agent runs your unit tests, your integration tests,

278
00:10:42,400 --> 00:10:45,360
and if you've set them up, contract tests against stop services.

279
00:10:45,360 --> 00:10:47,000
When tests are brittle, it files issues

280
00:10:47,000 --> 00:10:49,480
with precise failure output and recommended fixes.

281
00:10:49,480 --> 00:10:51,280
If a flaky test is blocking progress,

282
00:10:51,280 --> 00:10:54,240
it proposes quarantining it with a tag, documents the risk

283
00:10:54,240 --> 00:10:56,160
and keeps moving on non-risky areas,

284
00:10:56,160 --> 00:10:58,600
momentum without denial.

285
00:10:58,600 --> 00:11:00,000
Bench marks next.

286
00:11:00,000 --> 00:11:02,760
After the upgrades, stabilizes the agent runs targeted

287
00:11:02,760 --> 00:11:05,320
throughput and latency tests against the same workloads

288
00:11:05,320 --> 00:11:06,440
as baseline.

289
00:11:06,440 --> 00:11:09,280
The impact is where Java 21 earns its keep.

290
00:11:09,280 --> 00:11:11,680
More concurrent requests on the same CPU budget

291
00:11:11,680 --> 00:11:13,880
due to virtual threats, lower tail latency

292
00:11:13,880 --> 00:11:17,000
thanks to GC improvements and fewer context switch penalties.

293
00:11:17,000 --> 00:11:18,280
You don't need to worship benchmarks

294
00:11:18,280 --> 00:11:21,000
to understand graphs that slope in the correct direction.

295
00:11:21,000 --> 00:11:22,560
The report calls out which improvements

296
00:11:22,560 --> 00:11:25,520
came from virtual threats versus GC tweaks.

297
00:11:25,520 --> 00:11:28,480
So you can credit the right feature when finance asks why

298
00:11:28,480 --> 00:11:30,440
the machines are suddenly less bored.

299
00:11:30,440 --> 00:11:31,960
Build hygiene matters.

300
00:11:31,960 --> 00:11:34,200
The agent normalizes maven wrappers,

301
00:11:34,200 --> 00:11:36,880
pins the tool chain to a Java 21 distribution

302
00:11:36,880 --> 00:11:39,800
you actually control and removes antique plug-ins

303
00:11:39,800 --> 00:11:42,200
that exist solely to make builds slow.

304
00:11:42,200 --> 00:11:44,720
It standardizes compiler flags, enables warnings

305
00:11:44,720 --> 00:11:46,760
as errors for the modules you approve,

306
00:11:46,760 --> 00:11:49,360
and adds static analysis where the signal is high.

307
00:11:49,360 --> 00:11:50,760
The goal isn't perfect.

308
00:11:50,760 --> 00:11:53,600
The goal is repeatable and dull, which is the gold standard

309
00:11:53,600 --> 00:11:54,600
for builds.

310
00:11:54,600 --> 00:11:56,560
Here's where the reclaimed hours show up.

311
00:11:56,560 --> 00:11:59,080
Historically, this kind of upgrade consumes weeks

312
00:11:59,080 --> 00:12:02,120
of senior engineer time, hunting transitive conflicts,

313
00:12:02,120 --> 00:12:03,880
unpicking arcane plug-in failures,

314
00:12:03,880 --> 00:12:05,520
and babysitting flaky tests.

315
00:12:05,520 --> 00:12:07,200
The agent compresses that into days,

316
00:12:07,200 --> 00:12:10,280
not by magic, by not getting tired, not getting distracted,

317
00:12:10,280 --> 00:12:12,080
and not inventing side quests.

318
00:12:12,080 --> 00:12:14,040
Your humans spend their time reviewing

319
00:12:14,040 --> 00:12:17,400
diffs and making judgment calls, not guessing version numbers.

320
00:12:17,400 --> 00:12:19,560
And when the loop converges, recipes applied,

321
00:12:19,560 --> 00:12:22,000
builds green, tests passing, scanners quiet,

322
00:12:22,000 --> 00:12:24,560
you have a clean branch with small well-labeled commits.

323
00:12:24,560 --> 00:12:27,640
Each message names the change, the rationale, and the source.

324
00:12:27,640 --> 00:12:29,680
Rollbacks are obvious, approvals are fast.

325
00:12:29,680 --> 00:12:31,400
Auditors can read them without calling you.

326
00:12:31,400 --> 00:12:34,320
Also, your page is silent, which is how you know modernization

327
00:12:34,320 --> 00:12:36,080
happened instead of cosplay.

328
00:12:36,080 --> 00:12:37,360
Modern runtime secured.

329
00:12:37,360 --> 00:12:39,480
The app is faster, safer, and frankly more adult.

330
00:12:39,480 --> 00:12:42,360
Now the Cloud Bill and topology need surgery.

331
00:12:42,360 --> 00:12:46,280
Cloud migration, AWS out as you're in with pipelines and policy.

332
00:12:46,280 --> 00:12:48,320
Everything changes when the runtime is sane.

333
00:12:48,320 --> 00:12:50,760
Now we move the furniture, target architecture first,

334
00:12:50,760 --> 00:12:53,040
because random lifting creates random outages.

335
00:12:53,040 --> 00:12:56,480
For a single spring MVC app that isn't pretending to be a service mesh,

336
00:12:56,480 --> 00:12:58,440
Azure app service is the efficient path.

337
00:12:58,440 --> 00:13:00,640
Simple deploys, built in scaling, and no surprise,

338
00:13:00,640 --> 00:13:01,640
Kubernetes cosplay.

339
00:13:01,640 --> 00:13:03,320
If you've got multiple spring microservices,

340
00:13:03,320 --> 00:13:05,440
service discovery, and config churn,

341
00:13:05,440 --> 00:13:08,280
Azure Spring apps earns its keep with managed spring bits

342
00:13:08,280 --> 00:13:09,760
and blue green out of the box.

343
00:13:09,760 --> 00:13:12,240
The agent doesn't guess, it scores the workload on features,

344
00:13:12,240 --> 00:13:14,000
statefulness, and traffic, then recommends

345
00:13:14,000 --> 00:13:15,520
with trade-offs and cost notes.

346
00:13:15,520 --> 00:13:17,520
You approve, it proceeds, data is next,

347
00:13:17,520 --> 00:13:19,720
and this is where adults separate from hobbyists.

348
00:13:19,720 --> 00:13:21,520
The mandate is Azure SQL Database.

349
00:13:21,520 --> 00:13:23,560
Yes, I heard your PostgreSQL nostalgia.

350
00:13:23,560 --> 00:13:26,320
Governance wants consolidation, identity wants managed auth

351
00:13:26,320 --> 00:13:27,880
and finance wants one bill.

352
00:13:27,880 --> 00:13:30,600
The agent inventories JDBC usage, connection pools,

353
00:13:30,600 --> 00:13:32,040
and driver assumptions.

354
00:13:32,040 --> 00:13:34,880
It swaps the driver, updates the JDBC URL,

355
00:13:34,880 --> 00:13:37,240
adds retry logic, suited for transient errors,

356
00:13:37,240 --> 00:13:41,440
and services and CSQL deltas where you wrote dialect-specific queries.

357
00:13:41,440 --> 00:13:42,920
If migration friction is high,

358
00:13:42,920 --> 00:13:45,720
it proposes an interim landing zone on Azure Database

359
00:13:45,720 --> 00:13:48,640
for PostgreSQL with a future cutover plan.

360
00:13:48,640 --> 00:13:50,960
Clearly labeled, timelines included.

361
00:13:50,960 --> 00:13:53,200
Options with receipts.

362
00:13:53,200 --> 00:13:55,360
Containerization isn't a personality trait.

363
00:13:55,360 --> 00:13:57,040
It's a repeatability tool.

364
00:13:57,040 --> 00:13:58,440
The agent generates a Docker file

365
00:13:58,440 --> 00:14:00,880
that actually builds multi-stage minimal base image,

366
00:14:00,880 --> 00:14:02,840
non-root user health checks.

367
00:14:02,840 --> 00:14:05,600
It bakes in JVM flags aligned to Java 21

368
00:14:05,600 --> 00:14:08,720
and your memory budget, not a random copy from a blog.

369
00:14:08,720 --> 00:14:11,960
Then it emits infrastructure as code, bicep, or ARM templates

370
00:14:11,960 --> 00:14:14,160
to provision app service or Azure Spring apps,

371
00:14:14,160 --> 00:14:17,600
app service plans, key vault identities, and networking.

372
00:14:17,600 --> 00:14:21,080
One environment definition per stage, death, test, port,

373
00:14:21,080 --> 00:14:22,480
same shape, different sizes.

374
00:14:22,480 --> 00:14:25,480
Fewer surprise failures because the machine stop improvising.

375
00:14:25,480 --> 00:14:28,520
CACD is where the will deploy later mid-goes to die.

376
00:14:28,520 --> 00:14:30,280
Enter GitHub actions.

377
00:14:30,280 --> 00:14:32,200
The agent scaffolds workflows that build

378
00:14:32,200 --> 00:14:35,720
with the PIND Java 21 tool chain, run tests and scanners,

379
00:14:35,720 --> 00:14:37,240
build and scan container images,

380
00:14:37,240 --> 00:14:40,200
and deploy through environments that require approvals.

381
00:14:40,200 --> 00:14:42,400
Rollbacks are a button, not a sayons.

382
00:14:42,400 --> 00:14:45,400
Previous image tags, previous slot, previous template.

383
00:14:45,400 --> 00:14:48,720
It wires smoke tests post-deploy and gates promotion on success.

384
00:14:48,720 --> 00:14:52,000
You don't hope prod looks like tests, the pipeline enforces it.

385
00:14:52,000 --> 00:14:54,200
Secrets are not environment variables in plain text.

386
00:14:54,200 --> 00:14:55,400
They live in key vault.

387
00:14:55,400 --> 00:14:57,800
The agent provisions vaults, creates references,

388
00:14:57,800 --> 00:14:59,960
and switches the app to managed identity.

389
00:14:59,960 --> 00:15:02,960
That means no embedded keys, no accidental config

390
00:15:02,960 --> 00:15:04,560
commits and no late night rotations

391
00:15:04,560 --> 00:15:06,760
because someone leaked credentials in a screenshot.

392
00:15:06,760 --> 00:15:08,720
It also adds conditional approvals.

393
00:15:08,720 --> 00:15:11,320
Security reviews happen when the S/B ARM changes,

394
00:15:11,320 --> 00:15:13,760
cost reviews trigger when plan sizes increase,

395
00:15:13,760 --> 00:15:16,280
and break class is logged when you override.

396
00:15:16,280 --> 00:15:19,120
Guard rails without friction, adults keep receipts.

397
00:15:19,120 --> 00:15:20,640
Cost reduction isn't a prayer,

398
00:15:20,640 --> 00:15:22,640
it's architecture plus policy.

399
00:15:22,640 --> 00:15:25,520
The agent write sizes plans based on measured CPU and memory,

400
00:15:25,520 --> 00:15:26,360
not ego.

401
00:15:26,360 --> 00:15:28,560
For non-production, it recommends scale to zero

402
00:15:28,560 --> 00:15:31,000
or consumption style options were supported.

403
00:15:31,000 --> 00:15:34,200
For production, it sets auto-scaling rules on real signals,

404
00:15:34,200 --> 00:15:36,800
requests per second, CPU, Q-depth,

405
00:15:36,800 --> 00:15:38,760
and caps maximum instance counts

406
00:15:38,760 --> 00:15:40,800
with a documented exception process.

407
00:15:40,800 --> 00:15:44,040
Egress gets trimmed by collocating services and switching chatty

408
00:15:44,040 --> 00:15:46,640
nightly jobs to intra-region parts.

409
00:15:46,640 --> 00:15:49,360
The before and after estimate lands in the repo.

410
00:15:49,360 --> 00:15:52,480
Instance hours, storage tiers, data transfer,

411
00:15:52,480 --> 00:15:54,880
finance recognizes numbers, give them numbers.

412
00:15:54,880 --> 00:15:57,120
Network and reliability aren't afterthoughts either.

413
00:15:57,120 --> 00:15:59,240
The templates add health probes, readiness checks,

414
00:15:59,240 --> 00:16:02,240
and connection draining so your user stop noticing deploys.

415
00:16:02,240 --> 00:16:04,480
If compliance demands private endpoints,

416
00:16:04,480 --> 00:16:06,960
it sets them up, pushes traffic through application gateway

417
00:16:06,960 --> 00:16:09,160
or front door, and configures WAV policies

418
00:16:09,160 --> 00:16:10,440
you can actually read.

419
00:16:10,440 --> 00:16:13,640
Logging routes to Azure Monitor with structured fields.

420
00:16:13,640 --> 00:16:17,120
Dashboards pre-baked, latency, error rate, saturation.

421
00:16:17,120 --> 00:16:18,600
Boring visibility is the goal.

422
00:16:18,600 --> 00:16:20,320
Cut over, follow the script, not vibes.

423
00:16:20,320 --> 00:16:21,720
The agent stages the environment,

424
00:16:21,720 --> 00:16:23,320
deploys to a new slot or instance,

425
00:16:23,320 --> 00:16:26,360
warms it with synthetic traffic and runs contract checks.

426
00:16:26,360 --> 00:16:29,320
Then a controlled switch, DNS TTLs adjusted if needed,

427
00:16:29,320 --> 00:16:32,240
slot swap if app service, traffic splitting if spring apps,

428
00:16:32,240 --> 00:16:35,800
rollback plan remains armed until user traffic proves the point.

429
00:16:35,800 --> 00:16:37,680
The report calls out impact windows

430
00:16:37,680 --> 00:16:40,120
who approved what and where the escape hatch lives.

431
00:16:40,120 --> 00:16:41,960
This is how you avoid 2AM folklore.

432
00:16:41,960 --> 00:16:44,360
Policy integration ties the room together.

433
00:16:44,360 --> 00:16:46,320
Approvals for security sensitive changes,

434
00:16:46,320 --> 00:16:48,360
cost checks for plan upgrades and compliance

435
00:16:48,360 --> 00:16:50,440
at the stations baked into the workflow.

436
00:16:50,440 --> 00:16:52,520
Every action lands and get with rationale.

437
00:16:52,520 --> 00:16:55,200
Auditors see intent, change, and verification.

438
00:16:55,200 --> 00:16:57,520
No black box, just a disciplined choreography

439
00:16:57,520 --> 00:16:58,960
where the agent does the heavy lifting

440
00:16:58,960 --> 00:17:00,240
and you retain the steering wheel.

441
00:17:00,240 --> 00:17:03,240
Result AWS out, Azure in, pipelines humming,

442
00:17:03,240 --> 00:17:06,920
policy enforced, and the cloud bill finally acting like it's on your side.

443
00:17:06,920 --> 00:17:07,840
You're welcome.

444
00:17:07,840 --> 00:17:09,280
Results and benchmarks.

445
00:17:09,280 --> 00:17:12,400
Time, CVEs, cost, and hours.

446
00:17:12,400 --> 00:17:15,360
Let's talk outcomes, not vibes, timeline first.

447
00:17:15,360 --> 00:17:16,960
The upgrade and migrate sequence

448
00:17:16,960 --> 00:17:19,920
that historically swallows a quarter went from months to days.

449
00:17:19,920 --> 00:17:22,520
Assessment and plan in hours, Java 21 upgrade

450
00:17:22,520 --> 00:17:23,680
in a couple of working days,

451
00:17:23,680 --> 00:17:27,040
cloud migration prep and pipelines inside the same sprint.

452
00:17:27,040 --> 00:17:30,240
Calendar effect, feature stop queuing behind upgrade season

453
00:17:30,240 --> 00:17:31,440
because there is no season,

454
00:17:31,440 --> 00:17:33,920
just disciplined automation running continuously.

455
00:17:33,920 --> 00:17:36,520
Security next, CVEs don't care about your roadmap.

456
00:17:36,520 --> 00:17:38,240
The agent moved critical and high findings

457
00:17:38,240 --> 00:17:41,800
from present and exploitable to resolved, regenerated the S-bomb

458
00:17:41,800 --> 00:17:44,560
and produced scanner reports that matched reality.

459
00:17:44,560 --> 00:17:46,920
Residual medium and low items were documented

460
00:17:46,920 --> 00:17:49,760
with reachability notes and remediation timelines.

461
00:17:49,760 --> 00:17:52,600
The important bit, risk trend turns down and stays down

462
00:17:52,600 --> 00:17:54,600
because the pipeline reskands on every change.

463
00:17:54,600 --> 00:17:57,000
Cost reduction shows up where finance actually looks.

464
00:17:57,000 --> 00:18:00,160
Compute hours, right size to reload, non-prod environment

465
00:18:00,160 --> 00:18:02,200
set to scale to zero, we're supported

466
00:18:02,200 --> 00:18:05,880
and egress trimmed by collocating chatty services.

467
00:18:05,880 --> 00:18:09,280
Before, instances idling at single digit CPU,

468
00:18:09,280 --> 00:18:11,400
transfer charges spiking on nightly jobs,

469
00:18:11,400 --> 00:18:13,600
storage hoarding data you'll never read.

470
00:18:13,600 --> 00:18:16,120
After instance counts align to demand curves,

471
00:18:16,120 --> 00:18:18,440
batch jobs stay in Trabi region, storage tiers,

472
00:18:18,440 --> 00:18:19,920
match access patterns,

473
00:18:19,920 --> 00:18:23,000
the number that embarrassed finance and delighted security,

474
00:18:23,000 --> 00:18:25,680
total monthly run cost dropped while CVE account dropped,

475
00:18:25,680 --> 00:18:27,480
fewer dollars, fewer vulnerabilities,

476
00:18:27,480 --> 00:18:29,160
both graphs moved down together,

477
00:18:29,160 --> 00:18:30,520
that never happens by accident.

478
00:18:30,520 --> 00:18:32,720
Developer hours reclaimed aren't theoretical.

479
00:18:32,720 --> 00:18:34,960
Senior engineer stopped babysitting dependency roulette

480
00:18:34,960 --> 00:18:36,080
and brittle builds.

481
00:18:36,080 --> 00:18:38,720
The agents loop, apply build test patch,

482
00:18:38,720 --> 00:18:41,240
replaces the least creative part of their job.

483
00:18:41,240 --> 00:18:43,960
Those hours shift to performance work that compounds,

484
00:18:43,960 --> 00:18:46,400
optimizing hot endpoints, deleting dead features,

485
00:18:46,400 --> 00:18:48,240
improving observability.

486
00:18:48,240 --> 00:18:50,000
portfolio wide, the pattern scales.

487
00:18:50,000 --> 00:18:52,800
Once your playbook exists in Git, other apps adopted

488
00:18:52,800 --> 00:18:54,800
and the upgrade tax stops accruing.

489
00:18:54,800 --> 00:18:56,920
Reliability signal improves because the pipeline

490
00:18:56,920 --> 00:18:58,520
enforces adulthood.

491
00:18:58,520 --> 00:19:00,840
Build success rates climb, test pass rates,

492
00:19:00,840 --> 00:19:02,680
stabilize after flake quarantine

493
00:19:02,680 --> 00:19:05,400
and rollback drills become a button instead of a ritual.

494
00:19:05,400 --> 00:19:08,160
Deploy frequency increases without error rate penalties

495
00:19:08,160 --> 00:19:11,120
because the shape of dev, test and prod stops drifting.

496
00:19:11,120 --> 00:19:13,040
Confidence becomes a metric, not a speech.

497
00:19:13,040 --> 00:19:14,480
Transparency ties it together.

498
00:19:14,480 --> 00:19:15,600
Every change is a small,

499
00:19:15,600 --> 00:19:18,120
reviewable commit with rational and references.

500
00:19:18,120 --> 00:19:19,800
Reports live beside code.

501
00:19:19,800 --> 00:19:22,240
Auditors answer their questions without summoning engineers.

502
00:19:22,240 --> 00:19:25,640
Leadership sees cost, risk, and velocity in the same pain.

503
00:19:25,640 --> 00:19:28,240
And the pager, it's still quiet.

504
00:19:28,240 --> 00:19:31,560
Numbers matter, so you get them with receipts?

505
00:19:31,560 --> 00:19:33,720
Governance, audit, trail and model transparency.

506
00:19:33,720 --> 00:19:34,960
No black boxes.

507
00:19:34,960 --> 00:19:37,520
Tracability is the baseline, not an extra.

508
00:19:37,520 --> 00:19:40,000
Every action lens in Git with a reason and a link

509
00:19:40,000 --> 00:19:43,160
to an advisory, a recipe, a migration note.

510
00:19:43,160 --> 00:19:44,800
You don't approve AI magic.

511
00:19:44,800 --> 00:19:47,120
You approve specific documented changes.

512
00:19:47,120 --> 00:19:49,200
Rollback is a Git-revert, not a war room.

513
00:19:49,200 --> 00:19:51,120
Explainability isn't optional.

514
00:19:51,120 --> 00:19:53,920
The agent attaches Y notes to each fix,

515
00:19:53,920 --> 00:19:57,920
which CVE, which API deprecation, which as your guideline,

516
00:19:57,920 --> 00:20:00,360
model outputs map to standards you already recognize.

517
00:20:00,360 --> 00:20:02,720
If a suggestion deviates, it flags the variance

518
00:20:02,720 --> 00:20:03,920
and waits for a human.

519
00:20:03,920 --> 00:20:05,320
Control stays where it belongs.

520
00:20:05,320 --> 00:20:07,320
Controls are layered, not performative.

521
00:20:07,320 --> 00:20:09,520
Human in the loop checkpoints at plan approval,

522
00:20:09,520 --> 00:20:12,560
security sensitive changes, and environment promotion.

523
00:20:12,560 --> 00:20:14,520
Conditional gates trigger when S-bomb delta

524
00:20:14,520 --> 00:20:16,760
are large, when plan sizes increase cost,

525
00:20:16,760 --> 00:20:18,400
or when network posture changes.

526
00:20:18,400 --> 00:20:22,000
Breakglass exists, is logged, and is audited after the fact.

527
00:20:22,000 --> 00:20:24,080
Adult sign, systems remember.

528
00:20:24,080 --> 00:20:26,440
Reporting is visible and dull, exactly right.

529
00:20:26,440 --> 00:20:28,440
Power BI dashboards pull from Git,

530
00:20:28,440 --> 00:20:31,680
scanners and pipeline runs, time-saved, CVE trend,

531
00:20:31,680 --> 00:20:33,320
cost curve, deployment health.

532
00:20:33,320 --> 00:20:35,840
You can filter by repo, team, or environment.

533
00:20:35,840 --> 00:20:38,560
That means governance reviews look at facts, not folklore.

534
00:20:38,560 --> 00:20:40,000
Compliance posture is repeatable

535
00:20:40,000 --> 00:20:42,040
because evidence packs assemble themselves.

536
00:20:42,040 --> 00:20:44,680
Commit history, S-bombs, scanner outputs,

537
00:20:44,680 --> 00:20:46,480
pipeline logs, and change approvals bundle

538
00:20:46,480 --> 00:20:48,760
into audit artifacts aligned to your frameworks.

539
00:20:48,760 --> 00:20:50,760
You run the play again next quarter,

540
00:20:50,760 --> 00:20:53,280
and the output matches because the process matches.

541
00:20:53,280 --> 00:20:55,880
So, should you still fix legacy Java by hand?

542
00:20:55,880 --> 00:20:57,120
No, obviously.

543
00:20:57,120 --> 00:20:58,280
Here's the takeaway.

544
00:20:58,280 --> 00:21:00,120
Manual modernization is waste.

545
00:21:00,120 --> 00:21:02,840
Agent-driven audited automation is the new baseline

546
00:21:02,840 --> 00:21:05,240
for speed, security, and cost control.

547
00:21:05,240 --> 00:21:08,360
If this saved you time, do the efficient thing, subscribe.

548
00:21:08,360 --> 00:21:10,520
Next, I'll wire the Power BI dashboard

549
00:21:10,520 --> 00:21:12,520
and pipeline triggers end-to-end,

550
00:21:12,520 --> 00:21:15,560
so your reports update themselves and your deploys behave,

551
00:21:15,560 --> 00:21:17,920
enable notifications, and stop learning by outage.
