AWS Organization accounts manangement

Question

Let's assume in current AWS organization we have 2 developers accounts. From what I found it is a good practice to create a separate AWS account per environment and give access to these resources.

My question is:

What is the best way to share access to the resources (e.g. EC2, EKS, EFS) for multiple developers? Now I see only these two options:

• Create a separate AWS account for each developer and allow to access some resources by applying roles to that developers AWS accounts.
• Within a root account of each AWS environment create a IAM user account for each developer and from that point manage permissions by policies and user groups.

Please let me know. I appreciate any type of help! :)

You should setup AWS SSO. Either integrated with your existing identity provider, or using the built in user system.

This will allow you to create permission sets. Then, you can assign permission sets to users in particular accounts. This will create a role in the account which the users can assume
