虚拟主机作为网络服务,最重要的就是系统的稳定性。稳定性左右着虚拟主机的在线率,直接关系到网站是否能够被访问的问题。虚拟主机性能的好坏又取决于服务器的配置及所使用操作系统、软件本身因素之外还一定程度下和机房所处的外界环境有关。带宽是速度的保证,服务器的速度,取决于带宽。而带宽指的是虚拟主机连接到每台服务器上的带宽,很多服务商在宣传时经常只宣传连接入机房的带宽值,却没有说明每台服务器的可用带宽。作为消费者应该格外小心。而作为影响服务器稳定的外在因素而言,机房的温度、湿度、人为管控也显得格外重要,这就与服务商机房的管理维护成本投入有关。大的服务商他的机房内的温度、湿度、人为管控极其严格,这就减少了服务器不稳定率。所以一般所谓的品牌主机的价格都是比较高的,这部分价格就是主机商用来维护机房的,所以也是情理之中。

服务器:服务器是指那些具有较高计算能力,能够提供给多个用户使用的计算机,通常又称为主机。服务器与客户机的不同点很多,例如客户机在一个时刻通常只为一个用户服务。客户机是通过终端给用户使用的,服务器是通过网络给客户端用户使用的。和客户机相比,服务器需要连续工作在7×24小时的环境。这就意味着服务器需要更多的稳定性技术RAS(Reliability, Availability and Serviceability,可靠性、可用性、适用性),比如支持使用ECC(Error Check and Correction,错误检查和纠正)内存。

Due to the large number of users using WordPress, several web hosting providers have chosen to offer managed WordPress hosting. An account with one of these providers only allow you to host WordPress based sites and nothing else. The benefit of managed WordPress hosting is that you do not have to worry about ANYTHING. They optimize your site for performance, make sure that your site is secure, and keep regular backups. On top of that they advise you if a specific plugin is having a negative impact.

Virtual Private Server (VPS) refers to a virtual machine. It is a method of partitioning a physical server computer into multiple servers with respects to the individual customer’s need. Even though, you are sharing the server with a handful others, this gives you almost as much control as a dedicated server. It also has the privacy of a separate physical computer and can be configured to run specific server softwares. Often developers, intermediate users, and medium-sized bloggers utilize VPS to scale their websites. If you do NOT have any technical knowledge, then you need to make sure that you purchase a managed VPS. This means that the WordPress hosting provider manages all system upgrades, and they are available to assist you if needed.

二、是否拥有机房,是否拥有一个可靠稳定, 主机 安全高速的机房是衡量一个成功的虚拟主机提供商的又一重要标准。在互联网行业,往往出现这样的情况:一些公司本身没有机房甚至根本没有机房,但是他们却往往以低于市场价格很多的价格向用户承诺各种服务。可想而知,缺乏足够的硬件支持,技术实力,这些承诺往往最终只能成为不切实际的空中楼阁。所以可以肯定的是:那些连机房的地点都不愿告诉客户的公司一定是含有欺诈成分的虚拟主机提供商,广大的用户应对这样的情况保持高度的警惕。

对比虚拟机实现资源和环境隔离的方案,docker就显得简练很多。docker Engine可以简单看成对Linux的NameSpace、Cgroup、镜像管理文件系统操作的封装。docker并没有和虚拟机一样利用一个完全独立的Guest OS实现环境隔离,它利用的是目前Linux内核本身支持的容器方式实现资源和环境隔离。简单的说,docker利用namespace实现系统环境的隔离;利用Cgroup实现资源限制;利用镜像实现根目录环境的隔离。

不管是哪一种双线,都需要对用户和服务器的IP地址进行解析才能选择线路,所以IP地址解析技术、设备和一个完善庞大的地址库是非常重要的--其原理是用户访问网站时先向DNS服务器查询这个网站的IP地址,而DNS服务器会判断用户是电信上网还是网通上网?是电信上网就返回电信IP地址;是网通上网就返回网通IP地址;这样实现智能判断,智能识别的目的。由于这种解析技术有一定的门槛,所以不是每个运营商都能够实现,而只有采用了智能 DNS 解析的双线主机才可以说的上是真正的双线服务。
