What are the steps to deploy an application revision in AWS CodeDeploy for Lambda functions?

1. Create an application; specify a deployment group; specify deployment configuration; specify AppSpec file

2. Build application; create runtime; configure environment; deploy version

3. Set up API; define version; allocate resources; deploy package

4. Create a function; set permissions; configure triggers; upload code

The correct answer is: Create an application; specify a deployment group; specify deployment configuration; specify AppSpec file

Deploying an application revision in AWS CodeDeploy for Lambda functions involves a specific process designed to ensure that your application is deployed correctly and efficiently. The correct option includes the essential steps required for this deployment. Creating an application is the foundational step where you define the application that you want to manage with CodeDeploy. This sets the stage for subsequent actions. Specifying a deployment group is critical as it defines the target where the application versions will be deployed. The deployment group allows you to manage and configure how the deployment is conducted, including defining which Lambda functions are involved. Next, specifying deployment configuration is important for controlling how the deployment will proceed. This configuration can include options about how to handle updates, such as rolling updates or complete shifts to the new version, determining the behavior during failures and successful deployments. Lastly, the AppSpec file defines the deployment rules and processes, including how Lambda functions are updated and any additional hooks or scripts that should be run during the deployment process. The AppSpec file acts as a blueprint during the deployment, specifying what needs to be done at various stages of the deployment lifecycle. In summary, this choice encapsulates all the necessary steps to successfully deploy an application revision using AWS CodeDeploy for Lambda functions, covering application definition, deployment target
