Build an AWS Multi-Account Strategy According to Best Practices

This blog post delves into the AWS Multi-Account Strategy, which uses multiple AWS accounts to manage workloads, resources, and users within an organization. The strategy enhances security, provides clear operational boundaries, and streamlines cost management. An AWS account is a container for cloud resources, and as environments grow in complexity, a well-structured multi-account approach becomes crucial. The benefits of an AWS Multi-Account Strategy include resource isolation, simplified cost tracking and allocation, centralized management and governance, and limits and service quotas management. To implement this strategy, organizations can leverage AWS Organizations and AWS Control Tower. AWS Organizations is a service that consolidates multiple AWS accounts into an organization managed centrally. It forms the backbone of the multi-account strategy, facilitating policy-based management and consolidated billing. On the other hand, AWS Control Tower provides an easy, quick, and prescriptive way to set up and govern a secure, compliant multi-account AWS environment. The default structure of AWS Control Tower includes a Management Account, Security OU, Sandbox OU, and IAM Identity Center Directory. Organizations can customize this structure according to their requirements. In summary, the AWS Multi-Account Strategy is essential for organizations targeting scalable, secure, and cost-effective AWS deployments and environments. By leveraging services like AWS Organizations and AWS Control Tower, businesses can build a robust multi-account setup that adheres to best practices and ensures efficient management of their cloud resources.
