Question
An ecommerce company manages its application's infrastructure by using AWS Elastic Beanstalk. A developer wants to deploy the new version of the application with the least possible application downtime. The developer also must minimize the application's rollback time if there are issues with the deployment. Which approach will meet these requirements?
Options
- AUse a rolling deployment to deploy the new version.
- BUse a rolling deployment with additional batches to deploy the new version.
- CUse an all-at-once deployment to deploy the new version.
- DDeploy the new version to a new environment. Use a blue/green deployment.
Explanation
A blue/green deployment creates a separate environment for the new application version and shifts traffic only after validation succeeds. This approach results in near-zero downtime and enables an immediate rollback by redirecting traffic back to the original environment if issues occur, making it the safest and fastest option for minimizing both downtime and rollback time.
