Answer 1

Canary

1. The canary release is a technique to reduce the risk of introducing a new software version in production by slowly rolling out the change to a small subset of users before rolling it out to the entire infrastructure.

2. It is about to get an idea of how new version will perform (integrate with other apps, CPU, memory, disk usage, etc).

Blue/Green:

1. It is more about the predictable release with zero downtime deployment.
2. Easy rollbacks in case of failure.
3. Completely automated deployment process
