An IT team has built an AWS CloudFormation template so others in the company can quickly and reliably deploy and terminate an application.The template creates an Amazon EC2 instance with a user data script to install the application and an Amazon S3 bucket that the application uses to serve static webpages while it is running.All resources should be removed when the CloudFormation stack is deleted.However, the team observes that CloudFormation reports an error during stack deletion, and the S3 bucket created by the stack is not deleted.How can the team resolve the error in the MOST efficient manner to ensure that all resources are deleted without errors?Read More →

A company uses AWS CloudFormation stacks to deploy updates to its application.The stacks consist of different resources.The resources include AWS Auto Scaling groups, Amazon EC2 instances, Application Load Balancers (ALBs), and other resources that are necessary to launch and maintain independent stacks.Changes to application resources outside of CloudFormation stack updates are not allowed.The company recently attempted to update the application stack by using the AWS CLI.The stack failed to update and produced the following error message: “ERROR: both the deployment and the CloudFormation stack rollback failed.The deployment failed because the following resource(s) failed to update: [AutoScalingGroup].”The stack remains in a status of UPDATE_ROLLBACK_FAILED.Which solution will resolve this issue?Read More →

A rapidly growing company wants to scale for developer demand for AWS development environments.Development environments are created manually in the AWS Management Console.The networking team uses AWS CloudFormation to manage the networking infrastructure, exporting stack output values for the Amazon VPC and all subnets.The development environments have common standards, such as Application Load Balancers, Amazon EC2 Auto Scaling groups, security groups, and Amazon DynamoDB tables.To keep up with demand, the DevOps engineer wants to automate the creation of development environments.Because the infrastructure required to support the application is expected to grow, there must be a way to easily update the deployed infrastructure.CloudFormation will be used to create a template for the development environments.Which approach will meet these requirements and quickly provide consistent AWS environments for developers?Read More →
