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?

BBlue-green

DRound-robin

Show Suggested 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.

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.

Canary deployment seems like a safer approach to test the new version.

Blue/Green deployment would be the best option to prevent outages.

I’m a bit confused about the differences between all these methods. I hope we can choose the one that allows for quick rollbacks if something goes wrong!

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.

I think canary releases might be useful here too, but I'm not entirely sure how they compare to blue-green.

I remember studying blue-green deployments, which can help minimize downtime during updates. Maybe that's the way to go?

Hmm, not sure which option is best here. I'll need to review the pros and cons of each deployment type to decide.

Ah, I've dealt with this kind of issue before. I'd go with a blue/green or canary deployment to safely deploy the new version.

Definitely need to be careful with this one. I'd probably recommend a gradual rollout or rolling update to ensure a smooth transition.

I'm a bit unsure about the best approach here. Maybe a canary deployment or A/B testing could help reduce the risk?

Hmm, this is a tricky one. I think a phased rollout or blue/green deployment could work well to minimize downtime.
