DevOps & Tooling

Overview

DevOps practices bridge the gap between writing code and running it in production. This domain covers our CI/CD standards, deployment approaches, environment consistency, and how we monitor what we ship.

Topics

• Environment Setup Standardisation — Consistent developer and production environment configuration
• Secrets Management — How we store, rotate, scope, and inject secrets across environments
• Infrastructure as Code — Managing infrastructure through version-controlled configuration
• Containerisation Standards — Building minimal, reproducible, and secure container images
• CI/CD Pipeline Best Practices — How we design and maintain our continuous integration and delivery pipelines
• Deployment Automation — Strategies for reliable, repeatable deployments
• Release Management — Separating deployment from release, using feature flags and progressive delivery to ship more safely
• Monitoring & Alerting — What we track in production and how we get notified when things go wrong
• SLOs & Error Budgets — Defining, measuring, and managing service reliability through objectives and error budgets
• Operational Readiness — The criteria a service must meet before it is trusted to production
• Incident Response & Postmortems — How we respond to production incidents, and how we learn from them without blame
