ABP extends the [ASP.NET Core distributed cache](https://docs.microsoft.com/en-us/aspnet/core/performance/caching/distributed).
ABP extends the [ASP.NET Core distributed cache](https://docs.microsoft.com/en-us/aspnet/core/performance/caching/distributed) to provide a more comfortable and easy-to-use cache service.
> **Default implementation of the `IDistributedCache` interface is` MemoryDistributedCache` which works in-memory.**See [ASP.NET Core's documentation](https://docs.microsoft.com/en-us/aspnet/core/performance/caching/distributed) to see how to switch to Redis or another cache provider. Also, see the [Redis Cache](./redis-cache.md) document if you want to use Redis as the distributed cache server.
> **Default implementation of the `IDistributedCache` interface is` MemoryDistributedCache` which works in-memory.**Memory cache is only useful if you are building a monolith application and you run a single instance of your application. For other cases, consider to use a distributed cache server. See the ***[Why to Use a Distributed Cache Server](../../kb/when-to-use-a-distributed-cache-server.md)*** document for more details.
