A startup is running several virtual machines (VMs) and Azure SQL Databases. They've noticed that their Azure costs are higher than expected, and they want to identify opportunities to reduce spending without impacting performance. Specifically, they need a service that can provide personalized recommendations for cost optimization, performance improvements, high availability, security, and operational excellence. Which Azure service should they regularly consult?

Why the other options are wrong

• B. Azure Service Health provides information about Azure service issues and planned maintenance, which is not focused on optimizing individual resource configurations or usage.
• C. Azure Monitor collects and analyzes telemetry data for performance and availability, but it primarily focuses on real-time insights and alerting, not proactive optimization recommendations across multiple pillars.
• D. Azure Cost Management + Billing helps analyze spending and create budgets, but it doesn't provide proactive, personalized recommendations across multiple optimization categories like Advisor.
