103.49.212.140服务器租用与虚拟主机,虚拟主机空间的区别

  随着互联网的发展,IDC行业如雨后春笋般蓬勃发展,虚拟主机空间,虚拟主机(包括VPS和云主机),整机租用以及服务器托管是服务商提供给用户四种基本的网站系统方式。今天着重的与大家分享一下河南虚拟主机,虚拟主机空间与服务器租用三者之间的区别。     三者概念的区别     服务器租用是指用户无须自己购买服务器,只需根据自己业务的需要,提出对硬件配置的要求。主机服务器由IDC服务商配置。用户采取租用的方式,安装相应的系统软件及应用软件以实现用户独享专用高性能服务器,实现WEB+FTP+MAIL+VDNS全部网络服务功能,用户的初期投资减轻了,可以更专著于自己业务的研发。主机提供商提供的主机租用服务的主机类型主要是基于Intel CPU的服务器,用户可以自行安装操作系统及相应的应用软件,并完全自行管理 ,也可由公司代用户安装系统、应用软件,免费提供服务器监测服务。     虚拟主机是使用特殊的软硬件技术,把一台运行在因特网上的服务器主机分成一台台“虚拟”的主机,每一台虚拟主机都具有独立的ip,具有完整的Internet服务器功能,虚拟主机之间完全独立,并可由用户自行管理,在外界看来,每一台虚拟主机和一台独立的主机完全一样。     虚拟主机空间是通过虚拟主机空间 ware Server虚拟化技术实现的虚拟服务器,虚拟化是一个抽象层,它将物理硬件与操作系统分开,从而提供更高的 IT 资源利用率和灵活性。     河南服务器租用优缺点     优点——服务器配置性能高,还能够满足特殊的定制需求,拓展性灵活,例如服务器的内存和硬盘容量的提高等。     缺点——缺陷是较为贵。升级扩充会牵涉到拆换物理设配。服务器迁移不便捷,要挪动设备。共享资源程度普通,物理服务器在租用期间只属于一个客户。     河南虚拟主机优缺点     优点——虚拟主机之间完全独立,由于多台虚拟主机共享一台真实主机的资源,每个虚拟主机用户承受的硬件费用、网络维护费用、通信线路的费用均大幅度降低。增加了服务器和通讯线路的利用率。     缺点——某些功能受到服务商的限制,比如可能耗用系统资源的论坛程序、流量统计功能等;访问速度及流量限制;虚拟主机不能由客户随意的安装软件及远程桌面等操作,自主性差。     河南虚拟主机空间优缺点     优点——价格最低,管理简单,诸如软件配置、防病毒、防攻击等安全措施都由专业服务商提供,大大简化了服务器管理的复杂性;网站建设效率提高,而租用虚拟主机通常只需要几分钟的时间就可以开通;     缺点——成百上千的站点共用一个ip;对网站流量有一定限制;某些虚拟主机网站访问速度过慢;能满足小部分中小企业要求。例如,传统型企业网站,网站仅做公司介绍用,及网站浏览者不多类型的可以选择用虚拟主机空间。
