What are some effective deployment strategies using Travis CI?

There are several effective deployment strategies you can use with Travis CI, such as blue-green deployments, canary releases, and rolling updates. Each has its own advantages depending on your application needs.

Can you explain blue-green deployments?

Sure! Blue-green deployment involves maintaining two identical environments, 'blue' and 'green.' You deploy the new version to the inactive environment and switch traffic to it once it's ready, minimizing downtime.

What about canary releases?

Canary releases allow you to deploy a new version to a small subset of users before rolling it out to everyone. This helps in monitoring the new version's performance and catching issues early.

How do I set up a rolling update with Travis CI?

To set up a rolling update, you can configure your Travis CI pipeline to gradually replace instances of your application with the new version, ensuring that some instances are always running the old version during the update.
