在同一台服务器上设置redis及其客户端应用程序(Setting up redis and its client applications on same server [closed])

 我正在查看设置配置平台/服务的选项，该配置平台/服务将为所有客户服务/应用程序提供配置。 要求是应在专用服务器上设置。 
 
 我正在探索redis是否可以作为支持复杂键值配置的可能选项之一。 如果要在与消费者不同的服务器上设置redis，那么GET会涉及一些网络延迟（我不太担心SET，因为它们将比GET少得多）。 我应该在客户端计算机上设置另一个缓存层（例如EhCache或其他）以避免机器到机器的网络延迟吗？ 在这种情况下，需要处理缓存同步和失效。 此外，我已经读过redis支持复制，但是客户端服务机器上的从服务器（它是主服务器的确切副本）将占用大量内存，因为redis主要使用RAM来存储所有数据。 而且，它们都可以竞争CPU /资源。 
 
 注意：客户端服务/应用程序当前部署在Amazon ec2媒体实例上。 类似的也可以用于redis。 
 
 如果这个架构有任何不错的选择，请告诉我，否则这一点都不好。 提前致谢。 

I'm going through the options for setting up a configuration platform/service which is going to serve configuration to all the consumer client services/applications. The requirement is that this should be set up on a dedicated server. 
 
I was exploring if redis could be one of the possible options to use for supporting complex key-value configuration. If redis is to be set up on a different server than that of the consumer, there will be some network latency involved with the GETs (I'm not that much worried about SETs as they will be very fewer than GETs). Should I be setting up another caching layer on the client machines (e.g. EhCache or something else) to avoid machine-to-machine network latency? Cache sync and invalidation needs to be handled in that case. Also, I've read that redis supports replication, but a slave server (which is the exact copy of the master) on the client service machine would then occupy good amount of memory as redis predominantly uses RAM to store all the data. Also, both of them can then compete for CPU/resources. 
 
Note: Client services/applications are currently deployed on Amazon ec2 medium instance. And a similar one might be used for redis as well.
 
Please let me know if there are any good alternatives with this architecture or this isn't good at all. Thanks in advance.
