Different types of deployments

Question

Accepted Answer

Different types of deployments include blue-green, canary, rolling, and immutable.

Blue-green deployment involves deploying a new version of the application alongside the old version, and switching traffic to the new version once it's ready.
Canary deployment involves gradually rolling out a new version of the application to a small subset of users, and monitoring for issues before rolling out to the rest of the users.
Rolling deployment involves gradually updating instances of the application with the new version, while keeping the old version running until all instances have been updated.
Immutable deployment involves creating a new set of instances with the new version of the application, and switching traffic to the new instances once they're ready.
