Introduction

Iterative approach to deployments

Progressive delivery is a deployment practice that aims to roll out new features gradually. It enforces the gradual release of a feature while, at the same time, trying to avoid downtime. It’s an iterative approach to deployments.

There we go. That’s the definition. It’s intentionally broad because progressive delivery encompasses quite a few practices, like blue/green deployments, rolling updates, canary deployments, and so on.

Soon we’ll see what it looks like in practice. For now, the most crucial question is not what it is, but why do we want it and which problems does it solve?
