Generic DevOps maturity models score you on culture slides — this one maps L1–L4 to AWS gates you can verify: IaC in Git, GitOps or gated CD, ADOT on EKS, FIS with stop conditions, and cost-aware CI. A composite 85-engineer SaaS moved from L2 to L3 in one quarter by fixing the CI/GitOps boundary alone, cutting deploy-related incidents from ~6/month to 2.

AWS CLI v2 #10196 chmod'd streaming outputs to 0600 — including /dev/null. July 2026 retrospective: #10215 revert, host repair, pin-and-canary checklist.

Real AWS DevOps practices from production: GitOps on EKS, OpenTelemetry, supply chain security, chaos engineering with FIS, and AI-assisted DevOps with Amazon Q.

CI/CD infrastructure is invisible until your DevOps bill hits $15,000/month. Build minutes, artifact storage, and ephemeral environments accumulate costs that few teams track. Here is how to measure and control them.

Production-grade GitHub Actions patterns for AWS workloads — OIDC authentication, pinned actions, blue-green deployments, build caching, and the security mistakes that leave your pipeline open to supply chain attacks.

CodePipeline isn't the most loved CI/CD tool — but it's the one that talks to every other AWS service natively. Pipeline architecture, CodeBuild configuration, cross-account deploys, and the patterns that ship code safely without bolting on a third-party runner.
