- 71. ARTIFACTS CONFIG DEVELOP TEST/VER/PROD • The world changes • Separate build from deploy • Archive • Write once only (immutable)
- 72. ARTIFACTS CONFIG DEVELOP TEST/VER/PROD • First class citizens • History • Audit • Roll back/revert • Public knowledge
- 74. ARTIFACTS CONFIG Frameworks Generate Code • Enforce standard patterns • From zero to “done” instantly • Quick on boarding • Easy refactoring • Quick development
- 75. ARTIFACTS CONFIG Frameworks Generate Code VERSION CONTROL • Branching strategy (gitflow) • Version strategy (maven) • Easy access (web-ui) • Distributed (git) • Feature commits
- 76. ARTIFACTS CONFIG Build CodeFrameworks Generate Code VERSION CONTROL • Standard tools (maven/ant) • Convention over configuration (the maven way) • Command Line • No configuration • No “installation”
- 77. ARTIFACTS CONFIG Test CodeBuild CodeFrameworks Generate Code VERSION CONTROL • Unit test • Whenever possible • Black-box testing • Some “online testing” • Remember usability (auto update)
- 78. ARTIFACTS CONFIG Release Code Test CodeBuild CodeFrameworks Generate Code VERSION CONTROL • One liner (release.py) • Manage dependencies (maven) • Manage versions (maven) • Manage version control (git) • Push to Artifact (maven) • Rollback on failure (release branch)
- 79. ARTIFACTS CONFIG Release Code Test CodeBuild CodeFrameworks Generate Code Edit Code VERSION CONTROL • Editor agnostic • No configuration • No magic
- 80. ARTIFACTS CONFIG Release Code Test CodeBuild CodeFrameworks Generate Code Edit Code VERSION CONTROL Review Code • Not to enforce policies • For education only • Everyone should review • “Pair programming”
- 81. ARTIFACTS CONFIG Release Code Update Config Test CodeBuild CodeFrameworks Generate Code Edit Code VERSION CONTROL Review Code • Version controlled (git) • Easy to edit/compare (web) • Connected to artifacts • Self documented
- 82. ARTIFACTS CONFIG Release Code Update Config Test CodeBuild CodeFrameworks Generate Code Create BOM Edit Code VERSION CONTROL Review Code • Simple text files (Bill of Material) • From comparing state (web) • From development • Describes state • Goes back and forwards
- 83. ARTIFACTS CONFIG Release Code Update Config Test CodeBuild CodeFrameworks Generate Code Create BOM Create Ticket Edit Code VERSION CONTROL Review Code • Work order • Describes why and what • When approved: done • Contains logs • Self service deploy

- 87. ARTIFACTS CONFIG Verify Code • Dependency mismatches • Accidental global changes • Invalid changes
- 88. ARTIFACTS CONFIG Verify Code Test Releases • Regression test • Acceptance test • Performance test
- 89. ARTIFACTS CONFIG Verify Code Test Releases Document Code • Think java doc • Generated from code • But focus is maintenance
- 90. ARTIFACTS CONFIG Verify Code Test Releases Document Code • See live metrics • Changes over time Monitoring
- 91. ARTIFACTS CONFIG Verify Code Test Releases Document Code Manage Config • Make sure “prod” is correct • Update when life changes • Does not require development Monitoring
- 92. ARTIFACTS CONFIG Verify Code Test Releases Document Code Manage Config Deploy • Apply configuration • Push to environment • Record logs • Update “state” Monitoring
