What are the best deployment strategies for AWS Elastic Beanstalk?

There are several deployment strategies for AWS Elastic Beanstalk, including All at Once, Rolling, Rolling with Additional Batch, and Immutable deployments. Each has its pros and cons depending on your application's needs.

Can you explain the Rolling deployment strategy?

Sure! In a Rolling deployment, Elastic Beanstalk updates a few instances at a time, ensuring that some instances are always running the previous version. This minimizes downtime and allows for a smoother transition.

What about the Immutable deployment strategy?

The Immutable deployment strategy creates new instances with the new version of your application and only swaps them in once they are healthy. This ensures that if something goes wrong, the old instances remain unaffected.

Which strategy is the safest?

The Immutable deployment strategy is generally considered the safest because it reduces the risk of downtime and allows for quick rollbacks if issues arise.
