What is the difference between blue green and canary deployment strategies?

Canary deployment is like blue-green, except it’s more risk-averse.

Instead of switching from blue to green in one step, you use a phased approach.

With canary deployment, you deploy a new application code in a small part of the production infrastructure..

How does the Canary work?

What is canary in computer science?

In software testing, a canary is a push of programming code changes to a small group of end users who are unaware that they are receiving new code. Because the canary is only distributed to a small number of users, its impact is relatively small and changes can be reversed quickly should the new code prove to be buggy.

Why is it called Canary release?

This technique is called “canary” releasing because just like canaries that were once used in coal mining to alert miners when toxic gases reached dangerous levels, a small set of end users selected for testing act as the canaries and are used to provide an early warning.
