How to compare the IAM with Landing zone accounts?:

AWS Identity and Access Management (IAM) and AWS Landing Zone are both important tools for managing access to AWS resources. However, they serve different purposes and have different functionalities.

IAM is a service that enables you to manage access to AWS resources by creating and managing AWS identities (users, groups, and roles) and granting permissions to those identities to access specific resources. IAM enables you to create and manage user accounts, control permissions, and enforce policies for access to specific AWS resources.

AWS Landing Zone, on the other hand, is a pre-configured and customizable solution that provides a standardized framework for setting up and managing multiple AWS accounts across an organization. Landing Zone is designed to help automate the deployment of new accounts, ensure compliance and governance across accounts, and improve the overall management of resources across multiple accounts.

To compare IAM with AWS Landing Zone, we can look at some key differences between the two:

IAM is focused on user and resource access management, while AWS Landing Zone is focused on the overall management of AWS accounts.
IAM provides fine-grained control over access to specific resources, while Landing Zone provides standardized security and compliance policies that are applied across multiple accounts.
IAM is primarily used to manage user access to individual AWS resources, while Landing Zone provides a centralized way to manage multiple AWS accounts.
IAM can be used in conjunction with Landing Zone to provide additional user and resource access management capabilities within the Landing Zone accounts.

In summary, IAM and AWS Landing Zone are complementary tools that can be used together to manage user access to AWS resources within Landing Zone accounts. While IAM provides fine-grained control over access to specific resources, AWS Landing Zone provides a standardized framework for managing multiple accounts and ensuring compliance and governance across those accounts.

Assume one Landing zone account is there. Can it have IAM ids also for different people access ?

Yes, a Landing Zone account can have IAM identities for different people to access. In fact, IAM is a core component of AWS Landing Zone and is used to manage access to resources within the Landing Zone account.

When you set up a Landing Zone account, you will typically create an AWS Organization, which is a collection of AWS accounts that you can manage centrally. Within the AWS Organization, you can create multiple AWS accounts for different teams or applications. Each of these accounts will have its own IAM identities for managing access to resources within that account.

In addition, you can also create IAM roles within the Landing Zone account that can be assumed by IAM identities from other accounts within the same AWS Organization. This enables you to grant access to specific resources in the Landing Zone account to users or applications in other accounts.

For example, you might create an IAM role in the Landing Zone account that allows access to a specific Amazon S3 bucket. You could then grant access to that role to an IAM identity in another account, enabling that user or application to access the S3 bucket.

In summary, IAM identities can be used to manage access to resources within a Landing Zone account, and roles can be used to grant access to those resources to IAM identities in other accounts within the same AWS Organization. This enables you to manage access to resources across multiple accounts in a centralized and secure way.
