Some agile terminology

Blue/Green deployment

This is where we deploy to a new site where we can test and approve the deployment before switching our audience to the new site.
The switch can be achieved by a load balancer or reverse proxy.

Canary release

This is similar to a Blue/Green deployment except a sample of the total audience to selected for the switch over. This sample can then approve the change before we switch everyone over.

A/B testing

This is about testing features and associated more with ui improvements.
A/B testing allows us to monitor conversion rates of new features and more about testing user behaviour and measuring response to new features.
