Let’s talk about deployments. This topic used to be considered an uninteresting implementation detail, but is now becoming a fundamental element for modern systems. I feel like everyone understand its importance, and is working to build solutions around it, but we are missing some structure and definition. People use different terms for same meanings, or same terms for different meanings. This leads to other people reinventing the wheel trying to solve their problems. We need a common understanding of this topic in order to build better tools, make better decisions, and simplify communication with each other.
This post is my attempt to list and define those common deployment strategies, which I called:
- Reckless Deployment
- Rolling Upgrade
- Blue/Green Deployment
- Canary Deployment
- Versioned Deployment
There are probably other names and terms you expected to see on this list. I’d argue that those “missing” terms can be seen as variants of these primary strategies.
And one final note before we begin: this post is about definitions, methodologies and approaches and not about how to implement them in any technology stack. A technical tutorial will follow in another post. Stay tuned!
