Compute Services

The Windows Azure Fabric provides an Internet-scale hosting environment that lives on Microsoft's data centers. The hosting environment provides a runtime execution environment for managed code, and might in the future include support for native code. The fabric handles load balancing and resource management and automatically manages the life cycle of a service based on requirements established by the owner of the service. The developer specifies the service topology, the number of instances to deploy, and any other necessary configuration settings. The fabric deploys the service and manages upgrades and failures.

A Windows Azure service is built from one or more roles which define a component to run in the execution environment; within the fabric, a service may run one or more instances of a role.

Currently the Windows Azure fabric supports two types of roles:
A service may be comprised of one or both types of roles. C# is currently the supported language for writing managed code to be deployed as roles.
