RamNode，美国商家，成立于2012年，主打美国洛杉矶、西雅图、纽约、亚特兰大VPS、VDS产品销售，其中VPS产品全部采用KVM架构。从2019年7月下旬开始RamNode所销售的VPS产品改为基于OpenStack平台的云服务器产品，从原来的按周期付费改成了按小时计费，最低配置为1核512M内存，$3/月、$0.0045/小时起，并且支持支付宝、微信、PayPal、信用卡等方式付款购买。
一、实惠方案
RamNode新上线的OpenStack平台云服务器产品主要分为“STANDARD KVM”（标准KVM）、“PREMIUM KVM”（高级KVM）、VDS三个类别，有洛杉矶云服务器、西雅图云服务器、纽约云服务器、亚特兰大云服务器可以选择，最低配置1和512M内存，$3/月、$0.0045/小时。按小时计费、支持安装自定义系统。下面列举的是三款低配方案。

下面两个图片展示的是标准KVM和高级KVM全部云服务器方案、配置及价格大家可以根据自己业务需要进行选择，标准KVM是SSD硬盘，高级KVM是NVMe硬盘。另外大家还可以根据自身需要选择DDoS过滤的IP价格为3美元/月，点击这里订购高防IP这里；如果流量不够用，超过默认流量收费为0.004美元/GB。存储空间（快照，ISO上传等）收费为0.05美元/GB/月。
二、RamNode云服务器购买教程
1、RamNode新上线的OpenStack平台云服务器产品购买相比之前还是有所不同的，我们首先点击这里注册一个账号并购买一个“OpenStack Cloud Account”，OpenStack云平台账户是免费的。
购买后如下图我们今天云平台管理页面。
2、进入云面板后如下图创建云服务器。
3、如果你自己购买的云服务器产品不需要使用了，如下图可以删除，删除后不会再扣费。
三、主机测评
在写此文章教程时，蜗牛也购入了洛杉矶、西雅图512M内存的云服务器产品各一台，下面是简单的国内速度、硬盘IO读写速度测试结果。洛杉矶、西雅图到国内三网速度，从下面测试结果来看较为一般，不过硬盘IO独享速度不错，更适合面向北美用户使用。
