AWS Organisations vs Multi VPC in one account

What are the advantages of using AWS Organisations and what are the disadvantages of using multiple VPC in a single account?

Mike Norris

Single account, multi-vpc is really only viable for a small amount of similar workloads/streams. Even a small environment if setup to best practice standards will feel cramped after a short amount of time if it’s all jammed in one account. Depending on your needs, you can easily start running into limits of a vpcs / endpoints in a single region. The point of a proper org is for security and reducing your blast radius. Even a small environment should have a handful of accounts managed by Control Tower or Org Formation. (Infrastructure as code as much as possible for repeatability).

I would recommend Control Tower if you are doing any significant workloads. It is about scalability and security.
