Immutable Infrastructure
Category: infrastructure
A strategy where infrastructure components are replaced rather than modified.
In an immutable system, you never "patch" a server. If you need an update, you build a brand new one and destroy the old one. It eliminates the "configuration drift" that makes old servers mysterious and hard to debug.
Common Examples
- Our CI/CD pipeline enforces immutable infrastructure, meaning production servers are never manually updated, only redeployed from clean images.
- Adopting an immutable infrastructure model has been the single biggest factor in increasing our production deployment reliability and uptime.
