This will allow us not only to check on a single stack at a time but also on multiple stacks and multiple regions in one operation.

If you use the principles of infrastructure as code to provision your cloud infrastructure, you get many benefits from it - repeatable, quick, and consistent deployments.

If anyone modifies the infrastructure through other means, like the AWS Management Console, then all bets are off and you may end up with a mess.

Fortunately, some tools can help to keep your cloud infrastructure tidy. If you use AWS CloudFormation, then you have a feature called Drift Detection which may help you detect when someone changes the infrastructure through other means than CloudFormation. Read further to see how you can use Drift Detection for your benefit.

This will not be a comparison of features for different solutions, but more around an organization, way of working, and philosophy. Will AWS CDK fit the way you work and organize, or might be striving for?
