Windows Azure Compute

A Hosted Service is a container for an Application.

An Application must consist of at least one Role.

A Role is Scalable to meet the demand of traffic.

Load Balance an Application using {0} based routing.

Performance – Route traffic to best suited Hosted Service based on ping.

Failover – Route traffic to standby Hosted Services while primary is offline.

Round Robin – Route traffic equally between configured Hosted Services.
