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 with features like Activate Connect. It eliminates the need to manage infrastructure, ensuring high performance, security, and availability. Cost-cutting features and single sign-on add value. However, more regions could be beneficial, improving integration and security protocols. Issues like schema uploading and CloudWatch errors occur. Implementation is easy and affordable without management costs, but group policy improvements and business solution integration are needed.
