AWS Directory Service

Why AWS Directory Service is Important:
AWS Directory Service is a crucial component for managing user identities and access control within AWS environments. It allows seamless integration with existing on-premises directories, enabling single sign-on (SSO) and centralized management of user credentials across AWS services and applications. Understanding AWS Directory Service is essential for the AWS Certified Cloud Practitioner exam, as it covers key concepts related to security, identity, and compliance.

What is AWS Directory Service?
AWS Directory Service is a managed service that provides directory capabilities in the AWS Cloud. It offers several directory types, including AWS Managed Microsoft AD, AD Connector, and Simple AD. These directory services enable you to use existing Microsoft Active Directory (AD) or Lightweight Directory Access Protocol (LDAP) directories, or create a new standalone directory in the cloud.

How AWS Directory Service Works:
1. AWS Managed Microsoft AD: This is a fully managed Microsoft Active Directory service that allows you to run AD in the AWS Cloud. It provides a highly available and scalable directory service without the need to manage the underlying infrastructure.
2. AD Connector: AD Connector is a proxy service that enables you to connect your existing on-premises Microsoft AD to AWS services. It allows you to use your on-premises AD credentials to access AWS resources and applications.
3. Simple AD: Simple AD is a standalone managed directory service that is compatible with Microsoft AD. It provides basic directory features and is suitable for small-scale deployments or applications that don't require the full functionality of Microsoft AD.

AWS Directory Service integrates with various AWS services, such as Amazon EC2, Amazon RDS, and AWS SSO, enabling seamless access control and authentication.
