http://avanu.com - It improve availability of critical applications
Network Traffic Manager delivers high availability for your applications by monitoring your endpoints and providing automatic failover when an endpoint goes down.
It improve responsiveness for high-performance applications
It allows you to run cloud services or websites in datacenters located around the world. Network Traffic Manager improves application responsiveness by directing traffic to the endpoint with the lowest network latency for the client.
It perform service maintenance without downtime
Now we can perform planned maintenance operations on our applications without downtime. Network Traffic Manager directs traffic to alternative endpoints while the maintenance is in progress.
Cloud-based applications and combine on-premises
Network Traffic Manager supports external, non optimize endpoints enabling it to be used with hybrid cloud and on-premises deployments, including the "migrate-to-cloud," "burst-to-cloud," and "failover-to-cloud" scenarios.
Distribute traffic for complex, large deployments
Using nested Network Traffic Manager profiles, traffic-routing methods can be combined to create sophisticated and flexible rules to support the needs of larger, more complex deployments.
But how Network Traffic Manager works?
Network Traffic Manager enables you to control the distribution of traffic across your application endpoints.
Network Traffic Manager provides two key benefits:
Distribution of Network traffic according to one of several Network traffic-routing methods.
Continuous automated monitoring of endpoint health and automatic failover when endpoints fail.
When a user attempts to connect to a service, it must first resolve the DNS name of the service to an IP address. The user then connects to that IP address to access the service.
The most important point to understand is that Network Traffic Manager works at the DNS level.
