负载均衡问题
只是一个简单的问题。
如果我想为 Railo / Coldfusion 应用程序设置故障点最少的负载平衡,那么以下两种设置中哪一种是最佳的,为什么?或者说,它们会是一样的吗?
01) 设置 4 个 VPS 实例,每个实例具有 1GB RAM
或
02) 设置 1 个专用盒,具有 4GB RAM,其中 4 个 Railo / CF 实例,每个实例分配 1GB RAM
谢谢
Just a quick question.
If I wanted to set up load balancing for my Railo / Coldfusion application with the least fail points, which of the following two setups would be most optimal and why? Or, would they be the same?
01) Setup 4 VPS instances each with 1GB Ram
OR
02) Setup 1 Dedicated box with 4GB Ram with 4 Railo / CF instances each allocated 1GB ram
Thanks

如果您有 1 个专用盒子,那么您就会出现一个单点故障。

If you have 1 dedicated box then you have ONE single point of failure.

您需要分析打算在此集群上运行的应用程序,并评估是否需要轻松地将资源、CPU 和 RAM 重新分配给特定服务器。当您希望将所有流量从某个位置或类型定向到特定服务器时,就会出现这种类型的需求。示例包括搜索索引器、营销活动的登陆页面以及使用 IP 地址按区域划分流量。在每种情况下,您可能希望让接收此流量的服务器拥有更多资源(如果资源有限),并牺牲集群中其他服务器的资源。
You need to analyze the application(s) you intend to run on this cluster and evaluate if there's a need to easily be able to reallocate resources, CPU and RAM, to a particular server. This type of need arise in situations where you want to direct all traffic from a certain place or type to specific server(s). Examples include search indexers, landing pages of marketing campaigns, and splitting traffic by region using IP address. In each case you might want to make the server receiving this traffic have more resources, and if they're finite, and the expense of others in the cluster.
