DevOps & Release Engineering Topics
CI/CD pipeline design, build automation, deployment strategies, release management, artifact repositories, version control integration, and continuous delivery practices. Covers infrastructure automation for delivery workflows, release gates and approvals, multi-service orchestration, rollback strategies, and GitOps approaches. Distinct from Cloud & Infrastructure by focusing specifically on delivery automation and release processes rather than infrastructure platforms.
Mobile Build and Release Engineering
Delivery specific to mobile and device software: mobile build systems and CI/CD, app-store distribution and app lifecycle, mobile feature flags and progressive rollouts, and firmware update and deployment. Covers signing, store submission, staged mobile rollouts, and over-the-air update mechanics. Scoped to the platform-specific delivery concerns that general CI/CD topics do not address.
Pipeline Testing and Quality Gates
Automated testing wired into the delivery pipeline: test orchestration and execution in CI, quality gates and gating criteria, test environments and test-data management for pipelines, and scaling test infrastructure. Covers deciding what must pass before a change advances and keeping pipeline test stages fast and reliable. Scoped to testing as a delivery-gating concern; test strategy and craft belong to Testing, Quality & Reliability.
Safe Deployment and Rollback Strategies
Releasing changes to production safely and incrementally, and recovering when they fail: blue-green, canary, and rolling deployments, feature flags, dark launches, traffic shifting, and progressive rollout, together with rollback strategies, safe-deploy practices, blast-radius containment, automated recovery, and safe forward/backward migration. Covers deployment orchestration across cloud platforms, staged exposure of new behavior to users, assessing deployment risk, designing reversible releases, and restoring a known-good state quickly. Focuses on how a release reaches production and how it is unwound on failure, distinct from broader incident command, which lives in Enterprise Operations & Incident Management.
Build Automation and Artifact Management
Automating the build step and managing its outputs: compilation, dependency resolution, build reproducibility, artifact repositories, and container image creation and registries. Covers versioning schemes, semantic versioning, and backward/forward compatibility of published artifacts. The concern is producing, storing, and versioning deployable units rather than orchestrating their release.
