question 916

Multiple Choice

A Development team has an application stack consisting of many OS dependencies and language runtime dependencies. When deploying the application to production, the most important factor is how quickly the instance is operational. What deployment methodology should be used to update the running environments to meet the requirement?

• A) Use fully baked AMIs ("golden images") created after each successful build, creating a new Auto Scaling group, and blue/green deployments with rollbacks.
• B) Use user-data scripts to configure the instance correctly on boot by installing all dependencies when needed.
• C) Use an AWS Lambda function to only update the application locally on each instance, then re-attach it to the load balancer when the process complete.
• D) Use AWS OpsWorks scripts to execute on reboot of each instance to install all known dependencies, then re-attach the instances to the load balancer.
