Identity Center vs IAM users

What is a VPC: your own private network inside one AWS Region, example ThreeTierVpc 10.0.0.0/16.

Identity Center vs IAM users Creating an IAM user per person per account does not scale and leaves long-lived keys behind. Identity Center: one human identity, temporary roles per account. IAM users: long-lived per-account identities (use sparingly). Compute still uses IAM roles, not Identity Center. Move humans to Identity Center permission sets; keep IAM users only for break-glass or legacy tool

What this card says

Why do we need it?

Creating an IAM user per person per account does not scale and leaves long-lived keys behind.

What is it?

Identity Center: one human identity, temporary roles per account. IAM users: long-lived per-account identities (use sparingly). Compute still uses IAM roles, not Identity Center.

How to do it

Move humans to Identity Center permission sets; keep IAM users only for break-glass or legacy tools that cannot SSO.

Prefer Identity Center

Example

New hire gets one Identity Center user and group membership — not five IAM users across five accounts.
