When you are working with Azure cloud computing infrastructure, there are many benefits to creating and maintaining accurate Microsoft Azure diagrams.
You can effectively communicate your Azure network design to both technical engineering staff and also management where necessary. If you are onboarding new engineers, or engaging external consultants, you can bring them up to speed very quickly with a well laid out infrastructure diagram.
If you are taking on a new client or project, having access to infrastructure documentation is a massive advantage when trying to understand exactly what is running where. Back in our cloud consulting days, diagramming a new client's infrastructure was always the first job in the induction process. It was often time consuming, laborious but necessary in establishing exactly what was going on prior to starting work on improving or redesigning infrastructure.
