What is AppFabric Caching

AppFabric provides a distributed caching platform, used to develop highly scalable applications which require a cache to provide performance optimization. The caching platform can be scaled out by adding multiple cache servers to the architecture.

AppFabric caching platform takes care of sharing the cached objects across the cache servers automatically, and makes sure that the cache objects added to one of the instances is made available in all other instances.

Advantages of Distributed Caching

In general Caching improves performance of an application by storing frequently used information in the cache memory which is easily accessible when compared to the standard memory. Simple caching techniques can be used for smaller applications which get executed in a single server, however when it comes to larger applications which cannot run in a single server the simple caching techniques are not sufficient enough.

Larger applications required multiple servers, running in parallel to handle the huge volume of requests, hence we need Distributed Caching for large applications. The following are the advantages of using Distributed Caching.

Distributed Cache

Data is an important part of any application, in a conventions web application architecture which does not use any cache, data can be stored in 2 ways, using the database or using sessions, but both these options have their own limitations.

The database can store any amount of data, but fetching large amount of data from the database and displaying in the UI will bring performance of the application. Sessions are quick but there is a limitation on the amount of data that can be stored in session, adding more data to the session, consumes more memory and hence brings down the application performance.

Limitations of Asp.Net Cache

Asp.Net cache is a good approach to improve the performance of an application, frequently used data can be stored in the cache and re-used to avoid unwanted database hits. However Asp.Net cache has its limitations.

The following are the limitation of Asp.Net Cache.
