Specify Cache Policies with NCacheManager work that seamlessly manages a cache distributed across multiple computers. An administrator starts by specifying the cluster topologies and cache policies through the NCacheManager tool. The administrator can specify whether the cache is stored in memory or on disk, the eviction policies, and the maximum cache size, among other settings; these settings, as well as the topology, can NCacheManager includes an array of statistics that can be used to monitor the cache’s health and as metrics to mal performance. can specify whether the cache should be replicated or partitioned across the cluster. A replicated cache cluster has the same cache contents on each of the machines in the cluster. Since there is no single point of failure, a replicated cache improves reliability; however, any updates to the cache must be replicated to all of the clusters. Therefore, replicated clusters are ideal for read-dominated caches or small clusters. A partitioned cache, on the other hand, divides the cache contents among the computers in the cluster and boasts better performance for updates and large clusters. When evaluating frameworks like NCache, I am always interested in the learning curve and ease of integration. Mastering the NCacheManager tool and fully understanding the variety of contime, but plugging in the NCache API into your applications is a painless process. The classes in the NCache API closely match those of the caching API classes in the Microsoft .NET Framework and include HTTP Modules that make upgrading an ASP.NET application as simple as also includes a provider for integration into Microsoft’s Caching Application Block (CAB). In short, enhancing caching for your applications is a relatively straightforward process: existing code can be upgraded to using NCache with little or no changes to the code.
