John Morehouse breaks out the envelopes:
When organizations migrate workloads to Azure, the focus is usually on architecture, performance, and security. Cost management should be part of that conversation—but in practice, it’s often treated as an afterthought. One of the most overlooked and underutilized tools in Azure is Budgets, despite the fact that it can prevent unpleasant billing surprises with minimal effort.
Azure budgeting is useful but not great. I think it relies too much on messaging without enough teeth, so that requires setting up runbooks and humans constantly reacting rather than being able to set stronger rules around scaling down resources prior to getting that unexpected and unwelcome surprise bill.
