在线教育如何选服务器?

在线教育平台最难把握的就是视频质量,在各类网上课堂我们可以发现视频数据量大、直播常掉线、卡顿很多,但是能做到高质量直播教学的平台很少,很多直播平台都是没有质量保障的服务器,更不知道在线直播服务器需要满足的条件,不知道视频服务器的承载能力,满足不了视频直播的流畅性,更没有做好直播课程付费的安全保障,服务器选择很随意,但是每节课却可以影响到学习的学生。那么在线教育服务器如何选?

在线教育服务器如何选?

物理服务器:其实就是一台家用PC主机,它的整个硬件都是独立的,是单独的一台服务器,安全性好,性能要比vps服务器要高,也比VPS要贵。

vps服务器:可以将一台服务器分割成多个虚拟服务器,这样用户在进行使用时,他享受到的是独立的公网IP地址、不同的vps磁盘空间,独立的CPU资源、独立的内存、独立的操作系统,这能够使用户享受到独占使用计算资源的体验。

云服务器:云服务器在直播中是所有服务器中最常使用的服务器,它的优势有:第一,用户不需要购买硬件,就可以迅速的创建或释放任意多台云服务器,也就是说,它的能力要比其他服务器更好一些。第二点,它非常安全可靠,因其机制原因,它存放着的数据更不容易被外因所销毁。最后,在同样高的性能下,它要比独立服务器更划算一些。

如果按照服务器的作用来分的话,直播平台大约能够被分为业务服务器,视频服务器,流媒体服务器等多种服务器,在流媒体服务中,我们不得不提一提第三方cdn这个概念。

在搭建直播平台时,流媒体服务器的实现方式一般有两种,一是自建流媒体服务器,它的优势是它的性能非常的好,它的缺陷是它非常的贵,而且花费需要花费更多的时间,因为自建流媒体服务器顾名思义是要直播平台自己去建立的,而第三方cdn则可以直接接入使用,比较节约资金,并且在大城市中,它的性能往往会比自建流媒体服务器要好一些。

以上就是搭建直播平台所需的多种服务器,它们的优缺点都非常明确,用户可以根据自己的需求来决定用哪种服务器。

    • treatment for osteoporosis in women

      I acquired more new stuff on this losing weight issue. Just one issue is a good nutrition is vital if dieting. A big reduction in bad foods, sugary foodstuff, fried foods, sweet foods, pork, and white colored flour products may perhaps be necessary. Retaining wastes harmful bacteria, and contaminants may prevent aims for losing belly fat. While specified drugs momentarily solve the matter, the bad side effects are usually not worth it, they usually never give more than a short lived solution. It can be a known incontrovertible fact that 95% of fad diet plans fail. Many thanks sharing your notions on this site. https://osteoporosismedi.com treatment for osteoporosis in women
