Microsoft Silverlight 5 and Windows Azure Enterprise Integration
By :
Caching is an essential part of the tool that enables applications to scale in order to handle a large number of concurrent requests. This chapter will explore what data caching is and how it can improve the performance of your application. A sample application will be created that adds an AppFabric cache to RIA Services.
The topics covered will be as follows:
Data caching
Azure AppFabric caching
Caching raw data in AppFabric
ASP.NET session caching
Data caching is used to improve the performance of applications. The performance gains are achieved by creating a copy of the master data and storing it in a location that the consumer can access faster than the original data (for example, holding it in the memory rather than fetching it from a database). Caching is typically done on the data that is accessed frequently (such as lookup tables) or is expensive to obtain (long request times, data calculations, and so on.)
