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.

To reduce the cost of EC2 instances with a 1-year commitment across different regions, purchasing a Compute Savings Plan is the most suitable option.

Compute Savings Plan:

Compute Savings Plans provide the most flexibility and help to reduce your costs by up to 66%, offering savings on a variety of EC2 instance usage.

These plans apply to usage across any AWS Region, and they also apply to AWS Lambda and AWS Fargate usage.

Flexibility Across Regions:

Unlike Reserved Instances, which are tied to a specific instance family and region, Compute Savings Plans provide savings across any EC2 instance usage, regardless of region, instance family, operating system, or tenancy.

This flexibility is ideal for the company's requirement to migrate workloads from the eu-west-1 region to the eu-west-3 region within the commitment period.

Implementation:

Open the AWS Cost Management console.

Navigate to the "Savings Plans" section.

Purchase a Compute Savings Plan with a 1-year term.
