Generate a policy by using AWS Identity and Access Management Access Analyzer. AWS CloudTrail is a service that records all API calls made on your account. You can use this data to generate a policy with AWS Identity and Access Management Access Analyzer that only allows the permissions that the application requires. This will ensure that the application only has the necessary permissions and will protect the company from any unauthorized access.

AWS OpsWorks is a configuration management service that provides managed instances of Chef and Puppet. This service is designed to work seamlessly with Chef recipes, making it the most operationally efficient solution for continuing to use existing Chef recipes after migrating applications to AWS.

Creating an OpsWorks Stack:

Open the AWS OpsWorks console at AWS OpsWorks Console.

Create a new stack and select Chef as the configuration management engine.

Adding Layers:

Add layers to the stack that represent different parts of your application. Each layer can have its own set of Chef recipes.

Assign instances to these layers as needed.

Deploying Chef Recipes:

Upload your existing Chef recipes to the OpsWorks stack.

Configure the layers to use these recipes during setup, deployment, and other lifecycle events.
