CI/CD Platform Engineering

A book-shaped table of contents for CI/CD platform engineering: pipeline foundations, build/artifact/delivery platforms, GitHub Actions end to end (workflow mechanics through enterprise governance), Argo Workflows, Tekton, Jenkins, release engineering, platform security, observability, reliability, enterprise governance, and MAANG interview preparation — cross-linking existing tech/kubernetes/platform-engineering-fundamentals/system-design notes instead of duplicating them.

7 — GitHub Actions: Cost Optimization

Covers GitHub Actions minutes billing, storage costs, self-hosted runner economics, and concrete techniques to reduce CI spend.

1 — Multi-Cloud Delivery

Covers designing delivery pipelines that build and deploy consistently across more than one cloud provider.

2 — Multi-Region Deployments

Covers coordinating deployments across multiple regions with staggered rollout, region-aware promotion, and blast-radius containment.

3 — Multi-Tenant Pipeline Platforms

Covers isolating tenants — teams, business units, or customers — sharing a single CI/CD platform without leaking access, quota, or blast radius.
