但如何实现一个域名电信用户访问电信IP? 网通用户访问网通IP地址呢? 以前一般的做法是在网站首页做一个”电信站”和”网通站”,让电信用户和网通用户根据自己上网情况选择相应最快的线路。但实际多数用户在浏览网站时根本会忽略 “电信站”、“网通站”这样的链接,从而造成用户体验很差。智能双线主机就可以很好的解决这个问题。智能双线主机是提供的域名智能解析系统配合双线主机实现。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。智能双线主机避免了双线主机的手工切换过程,给网站每一个用户都最快速,最稳定的用户访问。可以说智能双线主机才是真正意义上的双线主机,才算是彻底解决电信网通互通难题。

After the speed test, we ran the Load Impact test on Bluehost servers. We gradually built up to 100 unique visitors at once to see how the server would handle increased requests from multiple connections at once.

To accurately measure performance across all WordPress hosting companies, we create a sample WordPress site on each hosting provider and install the default Twenty Seventeen theme. Next, we import dummy content including images and media so our test resembles an average user website.

Bottom line, managed WordPress hosting is hassle free fast WordPress hosting with high-quality support from staff with lots of WordPress experience. While all this sounds amazing, the plans for managed WordPress hosting is usually on the higher end of the scale. For example a personal account with a popular managed WordPress hosting provider costs $29/month where you can only host 1 site (getting maximum of 25,000 visitors per month). The next level higher where you are allowed multiple domains will cost you $99/month. A person starting out a blog cannot afford this.

WPBeginner is the largest unofficial WordPress resource site that receives millions of pageviews per month.

虚拟主机服务提供者除了必须掌控各种操作系统及相关操作系统的管理、优化,并具备在这些操作系统上进行系统级及应用级研发的能力(比如各种WEB服务器,邮件服务器,DNS服务器,负载均衡等),还必须具备广域网、局域网等网络管理能力(比如理解路由、交换等原理),以及电脑硬件的管理及配置数据库处理能力等。如果虚拟主机服务商没有专业的技术队伍提供如上所述的技术支持,则虚拟主机服务商不但只能提供贫乏的服务,而且服务的稳定性也无从确保。

In our in-depth WordPress hosting review, we came to a conclusion that if you are looking to start a blog, then you cannot go wrong with Bluehost. The fact that they offer you a free domain and free SSL for the price of $2.75 per month, it’s very hard to beat.

上面两个小节主要从运行在docker里的程序和运行在虚拟机里的程序进行性能比较。事实上,docker之所以如此受到开发者关注的另外一个重要原因是启动docker的系统代价比启动一台虚拟机的代价要低得多:无论从启动时间还是从启动资源耗费角度来说。docker直接利用宿主机的系统内核,避免了虚拟机启动时所需的系统引导时间和操作系统运行的资源消耗。利用docker能在几秒钟之内启动大量的容器,这是虚拟机无法办到的。快速启动、低系统资源消耗的优点使docker在弹性云平台和自动运维系统方面有着很好的应用前景。

We also use Load Impact service to send virtual users (VU) to each website to see how the hosting server would handle increased requests from multiple connections at once. This helps us see how the individual WordPress hosting company would perform during peak traffic times.

  云服务器的空间一般是可以自己选定的,一般都比较大,比如50G、100G等等。云服务器里的软件可以自己安装,你想安装什么服务都可以。一般买到的云服务器都是纯净的,除了操作系统,里面几乎没装任何软件,需要技术人员进行配置,比如配置WEB服务,这样才能支持网站访问。也正是因为这样,云服务器的维护成本也非常的高。服务器配置不是普通用户可以胜任的,需要专业的服务器技术人员才能配置好。因此,使用云服务器的朋友要注意了,除了云服务器本身的价格,你可能还要支出一定的技术维护费用。

数据通信系统中的主机又不同于一般的单机系统,其主要特点是:①面向通信,具有通信处理的能力。在硬件方面,具有与通信控制器连接的输入/输出通道部件或总线接口。系统软件具有对中央处理器(CPU)硬件中断的分析处理、输入输出控制和差错恢复处理、程序的启动和停止处理、多重处理和虚拟存储器管理等功能。通信控制程序(即通信软件)常与通信控制器相结合,控制用户的联机业务程序与远程终端之间的数据传输。②具有数据库管理功能。数据库是相互关联的数据的集合,具有数据的共享性、独立性和最小冗余性的特点,并对数据进行统一管理。计算机网的最重要应用之一,是网内主机之间建立地理上分散的数据库,主机通过数据库管理系统支持用户访问本地或远地数据库。③为保证高的可靠性,主机单机的可靠性要高,可设置备用机,或采取双机工作方式。

(2)docker利用的是宿主机的内核,而不需要Guest OS。因此,当新建一个容器时,docker不需要和虚拟机一样重新加载一个操作系统内核。我们知道,引导、加载操作系统内核是一个比较费时费资源的过程,当新建一个虚拟机时,虚拟机软件需要加载Guest OS,这个新建过程是分钟级别的。而docker由于直接利用宿主机的操作系统,则省略了这个过程,因此新建一个docker容器只需要几秒钟。另外,现代操作系统是复杂的系统,在一台物理机上新增加一个操作系统的资源开销是比较大的,因此,docker对比虚拟机在资源消耗上也占有比较大的优势。事实上,在一台物理机上我们可以很容易建立成百上千的容器,而只能建立几个虚拟机。
