传统的美国VPS难以实现

目前vps主机在美国非常流行,但随着用户对vps性能的需求不断增加,传统的vps已经越来越不能满足大型网站的需求。

近年来发展起来的美国云 VPS是一种虚拟专业服务器产品,其总体性能优于美国传统 VPS主机。仔细观察的网友可能会发现,如今许多美国主机商都加入了美国云 VPS计划,可以说,目前美国云 VPS和 VPS主机之间的竞争非常激烈。

传统的美国VPS难以实现

  但是对于许多朋友来说,也许不清楚美国的云vps和vps主机之间存在直接的差异,所以在选择上很困难。

一、概念不同

  在美国的 VPS主机中有一个美国专用服务器(假设美国服务器有64 GB RAM),它被划分为多个单位,所有单位都被虚拟化,每一个单位之间的区别称为 VDS或 VPS。

  云伺服器是云伺服器服务的一个重要部分,把提供资源的大型伺服器连在一起,再租给客户使用,使用者可根据需要扩充配置资源,一般只需几分钟即可完成,美国云伺服器是由美国云伺服器虚拟化而成的独立单位。

二、可用性能之间的区别

  如果使用美国 VPS,如果服务器或其中一部分服务器发生故障, VPS主机将关闭,并在问题解决之前导致停机。但是,当使用美国云 VPS时,如果出现任何故障,系统就会重新启动,并路由到另一个可用的云 VPS物理资源,从而有效地避免宕机事件。

三、资源分配的不同

  美国云 VPS完全独立于其他 VPS,并拥有专用的服务器资源,但在美国 VPS中,用户只获得可以均匀分布磁盘空间和特定带宽的虚拟环境,包括 CPU和内存资源等。

 举例来说,一个美国 VPS配置提供了1 GHz的 CPU和512 MB的内存,但这并不一定意味着它拥有如此大的 CPU和内存,而且可能更小。但是在美国云 VPS主机中,客户机与其它客户机的文件是完全隔离的,可以做到相对的“独立”,并且比美国 VPS主机更安全。

四、应用的操作系统不同

  基于所使用的虚拟化技术,美国 VPS只能同时安装一种操作系统。但在美国云计算 VPS主机上,用户可以自由地选择他们想要的任何操作系统,可以安装或替换各种可用的操作系统,切换系统非常方便。

五、付款模式不同

每一个槽都可用于美国云 VPS,并能在几秒内完成配置工作,可立即实现交易。但在美国 VPS中,对美国服务器虚拟化后的 VPS片进行分片处理需要一定的时间。而美国云型 VPS配置灵活,可扩展性强,能做到按时计费,传统的美国 VPS难以实现。
