虚拟服务器与真实服务器有何不同？

虚拟服务器现在一般都是云主机了，是很多硬件服务器在一起，聚集了一个很庞大的资源值上分化出来的一个一个独立的虚拟服务器，优点是扩展性好，成本低，缺点是稳定性不如物理机。

物理服务器就是一台实体机，稳定性好，内存和CPU扩展起来比较麻烦，有的机型还不支持扩展。

服务器买了之后还要托管到机房，硬件+托管，双份成本。

互联网以后的发展趋势一定是云服务器为主。

延展阅读：

虚拟服务器也称为VPS（VirtualPrivateService，虚拟专用业务）主机，简称为虚拟主机。

相对于真实主机而言，虚拟服务器是指采用特殊的软硬件技术把一台完整的服务器主机分成若干个主机。实际上是将真实的硬盘空间分成若干份，然后租给不同用户，每一台被分割的主机都具有独立的域名和IP地址，但共享真实主机的CPU、RAM、操作系统、应用软件等。

2.点击“自定义Mime类型”，然后在扩展名处填写您的文件格式扩展名，比如.rmvb  在Mime类型处填入Mime类型，比如 application/vhd.rn-realmedia

虚拟主机（英语：virtualhosting）或称共享主机（sharedwebhosting），又称虚拟服务器，是一种在单一主机或主机群上，实现多网域服务的方法，可以运行多个网站或服务的技术。虚拟主机之间完全独立，并可由用户自行管理，虚拟并非指不存在，而是指空间是由实体的服务器延伸而来，其硬件系统可以是基于服务器群，或者单个服务器。

其技术是互联网服务器采用的节省服务器硬件成本的技术，虚拟主机技术主要应用于HTTP，FTP，EMAIL等多项服务，将一台服务器的某项或者全部服务内容逻辑划分为多个服务单位，对外表现为多个服务器，从而充分利用服务器硬件资源。如果划分是系统级别的，则称为虚拟服务器。

扩展资料：

虚拟主机的关键技术在于，即使在同一台硬件、同一个操作系统上，运行着为多个用户打开的不同的服务器程式，也互不干扰。而各个用户拥有自己的一部分系统资源（IP地址、文档存储空间、内存、CPU等）。各个虚拟主机之间完全独立，在外界看来，每一台虚拟主机和一台单独的主机的表现完全相同。所以这种被虚拟化的逻辑主机被形象地称为“虚拟主机”。
