A decade of enterprise identity in the cloud with AWS Managed Microsoft AD

This article celebrates 10 years of AWS Managed Microsoft AD, a fully managed Microsoft Active Directory service that has become the identity backbone for thousands of enterprises worldwide.

• Launched in 2015 to solve operational overhead of managing on-premises Active Directory infrastructure
• Evolved through three editions: Standard (cost-effective), Enterprise (global scale), and Hybrid (extends existing domains)
• Integrated with 20+ AWS services including RDS, FSx, WorkSpaces, EC2, and IAM Identity Center
• Key innovations: multi-Region replication, schema extensions, CRUD APIs, Private CA integration, and self-service upgrades
• Enables centralized identity management across databases, file storage, end-user computing, and security services
• Hybrid Edition (2025) allows extending existing AD domains to AWS while retaining administrative control

AWS Managed Microsoft AD has evolved from a single managed service into a comprehensive identity platform that standardizes directory infrastructure across hybrid and multi-cloud environments.
