What is Azure Advisor and does it work the same way under CSP billing?

Azure Advisor is a free, built-in Azure service that analyzes your resource configuration and usage, then provides personalized recommendations across cost, security, reliability, operational excellence, and performance. It works identically regardless of whether you're billed directly or through a CSP Azure Plan — it's a feature of the Azure platform itself, not tied to your commercial billing relationship.

It's worth checking periodically even if you have a CSP partner, since it surfaces recommendations directly within your own tenant that you (or your partner) can act on.
