AWS CloudFormation creates and deletes all member resources of the stack together and manages all dependencies between the re-sources for you. Now before we dig into the details of cross-stack references in Serverless, let's quickly look at some of its details. Unlike name, the value doesn't need to be unique within the config, since you could have multiple stacks with the same name, but in different regions or accounts. Typically, CloudFormation creates a new resource (in case the existing resource cannot be updated), points any dependant resources to the new resource and then deletes the old resource. Give the stack a name, ex: prod-us-west-vpc; Change any default parameters if needed, then click "Next" and "Create" Your VPC will be created in the region the GUI is set to, and you can easily delete everything you created by deleting the CloudFormation stack. Use continuous deployment with Docker, Ansible, and AWS Elastic Beanstalk to take a greenfield project from the initial commit all the way to production. In the snippet below, you see the CloudFormation definition for the OpsWorks app. Some resources, like an IAM role that is tracked by name, may be re-created with the same exact name if they are manually deleted to get stack updates working once again.
