B
AWS IAM Identity Center
C
Amazon Cognito
D
AWS Identity and Access Management (IAM)
Explanation:
Explanation
Amazon Cognito is the correct choice for managing user sign-in for mobile applications with thousands of users because:
-
Amazon Cognito is specifically designed for mobile and web applications that need user authentication and authorization
-
It provides user pools that act as user directories with built-in sign-up and sign-in functionality
-
Supports social identity providers (Google, Facebook, etc.) and enterprise identity providers
-
Scales automatically to handle thousands of concurrent users
-
Provides secure token-based authentication
Why other options are incorrect:
-
AWS Directory Service: Primarily for integrating with Microsoft Active Directory for enterprise directory services, not optimized for mobile app user authentication
-
AWS IAM Identity Center: Used for centralized access management to multiple AWS accounts and business applications, not designed for mobile app user authentication
-
AWS IAM: Used for managing access to AWS resources and services, not for end-user authentication in mobile applications
For mobile applications requiring user authentication and management, Amazon Cognito is the recommended AWS service.
