Azure Advisor, now generally available, is your personalized cloud service for Azure best practices that will help you optimize Azure resources for high availability, security, performance, and cost.
Advisor will bring an all-new dashboard to help you more easily review the overall status of your recommendations across multiple subscriptions, along with downloadable reports and customization options to tune Advisor to your needs. You will be able to tag resource groups that you will want included in recommendations (for example, you'll be able to exclude non-production workloads), and adjust the CPU utilization threshold for identifying low usage virtual machines for each subscription.
Review your Azure Advisor recommendations at no cost in your Azure portal.
