A cloud engineer needs to deploy a new version of a web application to 100 servers. In the past, new version deployments have caused outages. Which option best deployment types should the cloud engineer implement to prevent the outages from happening this time?

Show Suggested Answer Hide Answer
Suggested Answer: C

A canary deployment is a pattern that reduces 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. It's an effective strategy to prevent outages since it allows for monitoring and quick rollback if issues arise without affecting all users. Reference: Canary releases are part of deployment strategies that can help mitigate the risk of outages during updates, a concept included in the CompTIA Cloud+ curriculum.

True, but blue-green seems safer for 100 servers. Less risk of outages.

Can we consider canary releases too? They test on a small scale first.

Haha, the cloud engineer should just roll back to the old version if it doesn't work. Easy peasy!

Why not just use a load balancer and gradually shift traffic to the new version? That should work.

I practiced a question about rolling updates before, and I think they could also reduce risk, but they might still cause some outages if not monitored closely.
