When you are deploying a new change into production, the associated deployment should be in a predictable manner. In simple terms, this means no disruption and zero downtime!
The safe strategy can be achieved by working with two identical infrastructures – the “green” environment hosting the current production and the “blue” environment with the new changes.
Blue-green deployment reduces downtime and risk by running two identical production environments called Blue and Green.
Why Go with Blue-Green Deployment Using Azure App Service Deployment Slots
Slots are free! No extra hidden fees.
You can test the feature on the staging slot before it swap!
After swap operation, if the changes aren’t as you expect, you can perform rollback which is swapping back without any downtime.
Slot Deployment feature is zero-downtime deployments.Read more about Blue-Green deployment in my blog at https://k21academy.com/az30327 which covers the following:
