redis - Azure 在内存 (IMemoryCache) 或 Redis (IDistributedCache) 中使用哪种缓存模型

Question

希望我能得到一些关于哪种缓存机制最适合 Azure 的说明。

目前我的应用程序使用内存中 (IMemoryCache) 来保存经常访问的数据。

此功能是否与在单个 Web 服务器上一样？即存储在内存中一次并由每个请求访问？还是 Azure Web 服务器场使这变得复杂？

根据上述问题的答案，我是否更好地使用 Redis 和 IDistributedCache 模型？

Answer 1

下面是Memory缓存和DistributedCache缓存的区别。您可以根据自己的需要进行选择。

The benefit of using Memory cache is it is simple and fast. However you cannot scale your Web Apps if you are using in memory provider since it is not distributed.

Distributed In Memory Session State Provider such as Redis Cache Session State Your Web App can have a simple, fast, and scalable Session State Provider. Because this provider stores the Session state in a Cache, your app has to take in consideration all the characteristics associated when talking to a Distributed In Memory Cache, such as transient network failures.
