Getting started with Simple AD - Amazon Directory Service
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Getting started with Simple AD

Simple AD creates a fully managed, Samba-based directory in the Amazon cloud. When you create a directory with Simple AD, Amazon Directory Service creates two domain controllers and DNS servers on your behalf. The domain controllers are created in different subnets in a VPC; this redundancy helps ensures that your directory remains accessible even if a failure occurs.
