The most valuable feature is that because it's all in the cloud, you don't need to manage the infrastructure.
AWS Directory Service offers ease of use and manageability, enabling efficient resource management and benefiting from robust cloud infrastructure, exceptional performance, availability, security features, and technical support. While integration with single sign-on is strong, group policy and business solution integration need improvement. The service has fewer regions than Azure, specifically in the Northeast, and challenges exist in schema uploading, directory setup, and manual configurations for on-premises integration and CloudWatch monitoring.
