A global traffic router working purely through DNS, with methods such as priority, weighted, performance and geographic, for any protocol. HTTP traffic never passes through it and it caches no content.

Each book explains Traffic Manager in context, with comparison tables and the common traps.
Terms in this definition
- AGDLP
Nesting pattern: users go into global groups, which go into domain local groups, which receive the permissions. AGUDLP adds universal groups for forests with several domains.
- DNS
The system that turns names into addresses. In Azure, private endpoints depend on private DNS zones, which are queried through 168.63.129.16.
- Priority
Routing method in Traffic Manager for active/passive failover: traffic goes to whichever healthy endpoint has the highest priority.
- Weighted
Distributes traffic among Traffic Manager endpoints in proportion to the weights assigned to them.
- Performance
Routing method in Traffic Manager that directs users to whichever endpoint offers the lowest latency.
- Geographic
A Traffic Manager routing method that picks the endpoint according to where the user is located geographically.
- HTTP
Hypertext Transfer Protocol, which sends data in clear text; VCF interfaces and APIs instead use HTTPS.
Related terms
- Azure endpoint
Kind of Traffic Manager endpoint pointing at an Azure service, such as a web app or a public IP resource that has a DNS name; a MultiValue profile can't use it.
- CheckingEndpoint
Interim Traffic Manager status an endpoint holds before its first probe result arrives; it continues to appear in DNS answers during that time.
- Degraded
Status Traffic Manager gives an endpoint whose health checks are failing. Such endpoints are omitted from DNS answers, except when all of them are degraded at once.
- External endpoint
Traffic Manager endpoint type pointing to an IPv4/IPv6 address or FQDN, which can be outside Azure. MultiValue routing accepts only External endpoints defined by IP address.
- MinChildEndpoints
Setting on a nested Traffic Manager endpoint, 1 by default, that says how many child endpoints must stay healthy. If fewer do, the parent regards the entire child profile as degraded.
- MultiValue
Traffic Manager routing method that answers each query with multiple healthy endpoints, at most 10. It accepts only External endpoints specified as IPv4 or IPv6 addresses.
- Nested endpoint
Lets a parent Traffic Manager profile include a child profile as one of its endpoints, so that two routing methods combine.
- Real User Measurements
Traffic Manager option where a JavaScript snippet in client pages measures latency to Azure regions and feeds the results into the latency table, which only Performance routing consults.
