Scale your .NET applications running in Windows Azure by removing performance bottlenecks related to data storage and databases. NCache is an extremely fast and linearly scalable Windows Azure in-memory distributed cache for .NET applications.
NCache lets you cache application data, store ASP.NET Session State, and cache ASP.NET View State for applications running in a multi-server configuration.
See more detail below about NCache in Windows Azure.
In this configuration, you allocate two or more NCache Virtual Machines as your caching tier and collocate this caching tier with your application in the same Virtual Network. Your .NET application can run as Web Role, Worker Role, or on its own Virtual Machine access this caching tier through a direct TCP connection to the cache cluster and without going through any publically addressable endpoint.
The benefit of this configuration is its speed and total privacy. The cache is very close to your application and therefore very fast to access because it does not have to go through any extra hops. And, it is within your Virtual Network and therefore totally hidden from the outside world.
In this configuration, you create a dedicated cache service in Windows Azure by allocating two or more NCache Virtual Machines and creating the cache on them. This cache is then accessible through the publically addressable endpoints of Azure Virtual Network.
The benefits of this configuration are as follows:
