Effective Strategies to Reduce Rollback Time for Application Versions

Answer - A.

Option B is incorrect because Elastic Beanstalk already has the facility to manage various versions.

You don't need to use S3 separately for this.

Option C is incorrect because in Cloudformation you will need to maintain the versions.

Elastic Beanstalk can do that automatically for you.

Option D is incorrect because the AutoScalingRollingUpdate policy is used in the CloudFormation template to specify the rolling updates for an ASG.

The policy is not for OpsWorks.

AWS Beanstalk is the perfect solution for developers to maintain application versions.

With AWS Elastic Beanstalk, you can quickly deploy and manage applications in the AWS Cloud without worrying about the infrastructure that runs those applications.

AWS Elastic Beanstalk reduces management complexity without restricting choice or control.

You upload your application, and AWS Elastic Beanstalk automatically handles the details of capacity provisioning, load balancing, scaling, and application health monitoring.

The correct answer for this scenario is A. Use Elastic Beanstalk and re-deploy using Application Versions.

Explanation: Elastic Beanstalk is an AWS service that simplifies the deployment, management, and scaling of web applications. It provides a platform for deploying and running web applications without the need for managing the underlying infrastructure. Elastic Beanstalk offers the capability of rolling back to a previous application version with a single click or command. This helps to reduce the time taken for rolling back the update.

Option B (Use S3 to store each version and then re-deploy with Elastic Beanstalk) is not the best option as it adds an extra step of manually managing the versions of the application.

Option C (Use CloudFormation and update the stack with the previous template) is not the best option as it involves managing the infrastructure at the template level, and rolling back the infrastructure could have its own challenges.

Option D (Configure an AutoScalingRollingUpdate policy for the Auto Scaling group in OpsWorks) is not the best option for this scenario as it does not address the application update rolling back issue. The AutoScalingRollingUpdate policy is used for updating instances in an Auto Scaling group gradually, allowing you to update instances with new versions of your application without downtime.

In summary, Elastic Beanstalk provides a straightforward solution for rolling back application updates. It can help the development team save time and avoid the need for managing complex infrastructure.
