AWS just released AWS Perspective, a new tool to help you create diagrams about your AWS workload/architecture.
In a way this is long overdue. There are quite a number of companies in this space already. AWS’ version supposedly is better integrated and allows you to link to the resource directly in AWS console.
It seems to be quite useful, though it doesn’t come cheap. Someone posted on Twitter that the cost estimate comes up to USD500+ (every month) to use it.
