Azure Advisor

What it is

Azure Advisor is a personalized cloud consultant built into the Azure portal. It analyzes your deployed resources and configuration, then surfaces a prioritized list of best-practice recommendations so you can optimize cost, harden security, and improve reliability and performance — without writing custom checks.

Why it exists

Azure is huge and every service has “best practices” that are easy to drift away from. Advisor centralizes that guidance into one score + action list, helping you answer “where am I wasting money?”, “are my resources secure?”, and “will this survive an outage?” — at tenant/subscription scale, for free.

Key ideas

Recommendations are grouped into five pillars (the exam’s “five categories”):

1. Cost — right-size/scale idle or over-provisioned resources (e.g. downsizing VMs, deleting unattached disks, terminating idle SQL/elastic pools).
2. Security — harden posture (e.g. enable MFA, apply security updates, Set-AzContext PIM-style alerts, enable NSG rules properly).
3. Reliability — improve redundancy & failover (e.g. add availability zones, enable backups, avoid single points of failure).
4. Performance — tune throughput (e.g. choose faster SKUs, add caching, right-size storage tiers).
5. Operational Excellence — simplify operations (e.g. enable diagnostics, remove unused resources, tag resources consistently).

Additional concepts:

• Advisor Score — a baseline (0–100) showing how well your subscriptions follow best practices, broken down by category; it rises as you implement recommendations.
• Filters & targeting: Score and recommendations can be scoped per subscription (and filtered by resource group / service), so you can track one workload at a time.
• Actions: Each recommendation explains the impact, shows affected resources, and links to the fix. You can dismiss (with a reason + optional reminder) or snooze recommendations you’ve decided not to act on.

Exam notes

• Remember the five categories: Cost, Security, Reliability, Performance, Operational Excellence (C-S-R-P-O).
• Advisor Score = your best-practices compliance baseline, per subscription, category-scoped.
• Advisor gives recommendations, it does not change resources automatically — it links you to the action to take yourself.
• It’s tied to the portal “Advisor” blade and works alongside azure-monitor (health) and cost-management (spend).
