AWS Control Tower vs. IBM Cloud Security Advisor

AWS Control Tower is great if you have multiple organizations or disciplines inside a company that needs to be separated for billing purposes or separation of concern. Multiple accounts is part of AWS's well-architected framework and are generally a good idea. AWS Control Tower makes central logging easy which enables those logs to be quickly picked up by a logging tool to provide even more reports and insight. For smaller organizations, AWS Control Tower may seem like an over-engineered solution

• This level of abstraction leaves you vulnerable to not knowing exactly what's been created, and that can enable you to mess things up.
• Because it provisions things on your behalf, you might end up paying for resources you don't need.
• The import process of existing accounts, which we did not end up pursuing, is tedious and manual.

There is no way to easily close an AWS account whether it was created manually or via the AWS Control Tower. It takes too many steps to close it vs to provision a new AWS account

Using AWS Systems Manager and other slightly lower level components has been helpful for us to manage parts of our AWS presence at a more granular level than AWS Control Tower was designed for. It's not at all an apples-to-apples comparison as they solve different use cases, but for us, the use case associated with AWS Systems Manager was a better fit for our specific needs and skillsets. We did not need everything that AWS Control Tower was doing for us.

Incentivized

• AWS Control tower allowed us to drop several third-party vendors for security appliances and logging, which saved us considerable funds.
• AWS Control tower reduced the amount of time we spend deploying AWS accounts.
• AWS Control tower reduced the amount of time we have to spend on quarterly security audits.
