About Deployment Patterns

Purpose

Deployment Patterns is a reference encyclopedia for engineering teams who deploy software to production. It covers the core deployment strategies -- blue-green, canary, rolling updates, and feature flags -- along with supporting techniques like zero-downtime migrations and rollback procedures.

Every guide includes concrete implementation details: Kubernetes manifests, load balancer configurations, database migration patterns, and cloud provider comparisons. The goal is to provide actionable reference material, not abstract theory.

What This Covers

• Deployment strategies -- Blue-green, canary, rolling updates, and feature flag deployments with step-by-step implementation guides.
• Cloud provider details -- AWS, GCP, Azure, and Kubernetes-native approaches compared side by side.
• Zero-downtime techniques -- Database migration patterns, connection draining, health checks, and readiness probes.
• Rollback procedures -- Decision matrices and concrete steps for every rollback scenario.
• Strategy comparison -- Structured tables comparing downtime risk, resource overhead, complexity, and suitability by use case.
