Azure Traffic Manager Cheat Sheet

• A DNS-based traffic load balancer.
• Improves the responsiveness of your applications by sending the request to the closest endpoint.
• It offers a range of traffic-routing methods and endpoint monitoring options.

Features

• It is resilient to failure.
• You can obtain actionable insights about your users using a traffic view.

• Improve the availability of your applications by using traffic manager health checks.
• Offers automatic failover when an endpoint goes down.
• Traffic Manager endpoints: Azure, External, and Nested
• Combine multiple traffic-routing methods using nested traffic manager profiles.
• Fast Failover for Critical Applications: A new routing method that performs health checks every 10 seconds (versus the standard 30 seconds), enabling much faster automatic failover for mission-critical endpoints.
• Performance Routing Enhancements: The performance routing method now utilizes Microsoft’s global Anycast network and an “Optimized Anycast” option for even lower latency by selecting the optimal network entry point.

Routing Methods

• Priority – allows you to set a primary endpoint for all traffic.

• Weighted – distribute traffic according to weights.

• Performance – routes users to the closest endpoint.

• Geographic – Direct users from specific countries/regions or entire geographic regions (e.g., ‘Middle East’, ‘South America’) to a designated endpoint. Supports over 70 geographic regions.

• Multivalue – endpoints for IPv4/IPv6 addresses.

• Subnet – Map groups of end-user IP address ranges to specific endpoints. Supports individual IPs, CIDR ranges (e.g., 192.168.0.0/16), and wildcards (*).

Azure Traffic Manager Pricing

• The first 1 billion DNS queries per month are provided free of charge for each Azure subscription. You are charged only for DNS queries that exceed this monthly free tier.
• You are also charged for each monitored endpoint.
• You can reduce your DNS query charges by configuring a larger TTL.
• You are charged for the number of data points used in the traffic view.
