A company manually provisioned a prototype infrastructure that includes an Auto Scaling group, an Application Load Balancer, and an Amazon RDS database. After validating the configuration, the company wants the ability to instantly deploy the same infrastructure for development and production across two Availability Zones in an automated way. What should a solutions architect recommend?

AWS CloudFormation is the ideal service for defining infrastructure as code. By creating a CloudFormation template based on the prototype, the company can reliably and repeatedly deploy identical environments (development and production) across multiple Availability Zones. This ensures consistency and automates the provisioning process. AWS Systems Manager is primarily for operational tasks like patching and automation, not for defining and deploying entire infrastructures. AWS Config is used for auditing and compliance, tracking resource configurations, not for deploying new infrastructure. AWS Elastic Beanstalk is a platform-as-a-service (PaaS) that simplifies deploying and managing applications, but it's less flexible for defining complex, custom infrastructure components like specific Auto Scaling group configurations or load balancer rules compared to CloudFormation.
