Traffic Manager Pricing

Geo-route incoming traffic to your app for better performance and availability

Azure Traffic Manager helps reduce the downtime and improve the responsiveness of important applications by routing incoming traffic across multiple deployments in different regions. Built-in health checks and automatic rerouting help ensure high availability if a service fails. Use Traffic Manager with Azure services, including Web Apps, Cloud Services and Virtual Machines, or combine it with on-premises services for hybrid deployments and smooth cloud migration.

Pricing Details

Traffic Manager billing is based on the number of DNS queries received, with a discount for services receiving more than 1 billion monthly queries. We also charge for each monitored endpoint (the rate depends on whether it’s an Azure or an external service.)

Price
First 1 billion DNS queries/month $- per million queries
Over 1 billion DNS queries/month $- per million queries
Health Checks (Azure) $- per Azure endpoint/month
Fast Interval Health Checks Add-on (Azure)* $- per Azure endpoint/month
Health Checks (External) $- per external endpoint/month
Fast Interval Health Checks Add-on (External)* $- per external endpoint/month

*Fast endpoint health checks need to be purchased as an add-on to basic endpoint health checks.

Support and SLA

  • Technical support for all Azure services released to General Availability, including Traffic Manager, is available through Azure Support, starting at $29.0/month. Billing and subscription management support is provided at no cost. Technical support is also available free of charge through community forums.
  • We guarantee that DNS queries will receive a valid response from at least one of our Azure Traffic Manager name server clusters at least 99.99% of the time. Availability is calculated over a monthly billing cycle. To learn more about our SLA, please visit the SLA page.

FAQs

  • Whenever a user accesses your application, a DNS query is used to map the name of your service to its IP address. By providing different responses to different DNS queries, Traffic Manager allows you to route incoming traffic across multiple hosted Azure services, whether they're running in the same data centre or across different data centres around the world.

    Traffic Manager provides you with a choice of traffic-routing methods, including performance, failover and round-robin. By using these to effectively manage your traffic, you can ensure high performance, availability and resiliency of your applications.

  • Traffic Manager enables you to improve the availability of your critical applications by monitoring your hosted Azure service endpoints and providing automatic failover capabilities when a service goes down.

    To do this, Traffic Manager continually monitors the health of each service endpoint. When these “Health Checks” detect that a service has gone down, Traffic Manager re-routes traffic to the other services.

  • Yes, the prices for DNS queries and health checks are the same, irrespective of the traffic-routing method being used.

  • When an end user's PC makes a DNS query, it doesn't contact the Traffic Manager name servers directly. Instead, these queries are sent via "recursive" DNS servers run by enterprises and ISPs. These servers cache the DNS responses so that other users' queries can be processed more quickly. Since these cached responses don't reach the Traffic Manager name servers, they don't incur a charge.

    The caching duration is determined by the "TTL" parameter in the original DNS response. This parameter is configurable in Traffic Manager – the default is 300 seconds and the minimum is 30 seconds.

    By using a larger TTL, you can increase the amount of caching done by recursive DNS servers and thereby reduce your DNS query charges. However, increased caching will also impact how quickly changes in endpoint status are picked up by end users, i.e. your end user failover times in the event of an endpoint failure will become longer. For this reason, we don't recommend using very large TTL values.

    Likewise, a shorter TTL gives more rapid failover times, but as caching is reduced, the query counts against the Traffic Manager name servers will be higher.

    By allowing you to configure the TTL value, Traffic Manager enables you to make the best choice of TTL based on your application's business needs.
