Which AWS service allows a data engineer to recreate their infrastructure securely in another AWS Region?

AWS CloudFormation is the service that allows a data engineer to recreate their infrastructure securely in another AWS Region. It is an infrastructure as code (IAC) service that enables developers and system administrators to define and provision AWS infrastructure using a declarative template in formats such as JSON or YAML.

By utilizing these templates, teams can consistently deploy their resources across various environments and regions, ensuring that configurations are uniform and reducing the potential for human error. CloudFormation manages the dependencies between resources, allowing for a coordinated creation or update of the entire stack, which is especially useful in complex setups involving multiple services.

While Amazon EC2, Amazon S3, and AWS Lambda are essential AWS services used for computing, storage, and serverless operations, respectively, they do not inherently provide capabilities for orchestrating the deployment and management of an entire infrastructure setup across different regions. AWS CloudFormation specifically focuses on the infrastructure aspect, making it the right choice for this scenario.
