A company sets up an organization in AWS Organizations that contains 10AWS accounts. A solutions architect must design a solution to provide access to the accounts for several thousand employees. The company has an existing identity provider (IdP). The company wants to use the existing IdP for authentication to AWS.

Which solution will meet these requirements?

A.
Create 1AM users for the employees in the required AWS accounts. Connect 1AM users to the existing IdP. Configure federated authentication for the 1AM users.
Answers
A.
Create 1AM users for the employees in the required AWS accounts. Connect 1AM users to the existing IdP. Configure federated authentication for the 1AM users.
B.
Set up AWS account root users with user email addresses and passwords that are synchronized from the existing IdP.
Answers
B.
Set up AWS account root users with user email addresses and passwords that are synchronized from the existing IdP.
C.
Configure AWS 1AM Identity Center Connect 1AM Identity Center to the existing IdP Provision users and groups from the existing IdP
Answers
C.
Configure AWS 1AM Identity Center Connect 1AM Identity Center to the existing IdP Provision users and groups from the existing IdP
D.
Use AWS Resource Access Manager (AWS RAM) to share access to the AWS accounts with the users in the existing IdP.
Answers
D.
Use AWS Resource Access Manager (AWS RAM) to share access to the AWS accounts with the users in the existing IdP.
Suggested answer: C

Explanation:

AWS IAM Identity Center:

IAM Identity Center provides centralized access management for multiple AWS accounts within an organization and integrates seamlessly with existing identity providers (IdPs) through SAML 2.0 federation.

It allows users to authenticate using their existing IdP credentials and gain access to AWS resources without the need to create and manage separate IAM users in each account.

IAM Identity Center also simplifies provisioning and de-provisioning users, as it can automatically synchronize users and groups from the external IdP to AWS, ensuring secure and managed access.

Integration with Existing IdP:

The solution involves configuring IAM Identity Center to connect to the company's IdP using SAML. This setup allows employees to log in with their existing credentials, reducing the complexity of managing separate AWS credentials.

Once connected, IAM Identity Center handles authentication and authorization, granting users access to the AWS accounts based on their assigned roles and permissions.

Why the Other Options Are Incorrect:

Option A: Creating separate IAM users for each employee is not scalable or efficient. Managing thousands of IAM users across multiple AWS accounts introduces unnecessary complexity and operational overhead.

Option B: Using AWS root users with synchronized passwords is a security risk and goes against AWS best practices. Root accounts should never be used for day-to-day operations.

Option D: AWS Resource Access Manager (RAM) is used for sharing AWS resources between accounts, not for federating access for users across accounts. It doesn't provide a solution for authentication via an external IdP.

SAML 2.0 Integration with AWS IAM Identity Center

By setting up IAM Identity Center and connecting it to the existing IdP, the company can efficiently manage access for thousands of employees across multiple AWS accounts with a high degree of operational efficiency and security. Therefore, Option C is the best solution.
