如今云计算的发展速度已经超出人们的想象,云服务和云应用被广泛应用,随着市场的变化,IDC行业新产品频出,云主机这一概念渐渐的被大众所熟知。
云主机是基于云计算平台的虚拟独立服务器,具有更高的灵性,可以让用户自主定义服务器配置,使资源充分利用。而云主机是若干台服务器组成的集群在同时提供服务,假设集群中的一两台服务器当机,也不会影响云主机的正常使用。
云主机的磁盘IO性能、带宽、内存等都不受制于单台服务器的限制,可以灵活方便地自由扩展。顾名思义,云主机是服务器集群基础上虚拟化。云计算时代,云主机以其可扩展性、安全可靠的特性深受广大企业级用户的欢迎。
云计算技术的出现,使数据中心的建设呈现出大型化、集约化的趋势,作为数据中心领域的先驱者,ISP行业更是纷纷步入其中。
云主机有它的优点所在,相比云主机,传统的虚拟主机也在云数据时代发挥其应有的功能作用。虚拟主机即共享主机,从互联网诞生至今,绝大部分站长都是从”共享主机”开始建站历程的。虚拟主机的技术实现了多个用户共享资源,共同分担运行费用,这就大大降低了每个用户的建站成本,为普及中小型网站提供了极大便利。
虚拟主机因其为个人、企业建站带来极大的方便而备受欢迎,虽经过多年发展,以及云主机普及应用,但虚拟主机辉煌程度依旧不减,这主要是归功于它自身的不断整合创新发展,并以国内外知名主机商HostEase、BlueHost为首的各大IDC商之间的不断发展的结果。
虚拟主机的低成本高利用率,迅速吸引了中小企业,因此适合对加快对投资小、收益快的网上交易平台的应用,加强电子商务、企业上网等信息化建设的力度,虚拟主机建站已成为提高企业竞争力的重要手段,因此备受国内外站长的青睐。
未来,云计算的大步迈进带动了虚拟化应用的全面迸发,引领了新一轮的技术革新,国内IDC行业风起云涌,面临的是频繁的产业洗牌格局,而市场的需求是奠定技术发展方向的源头,未来云计算、虚拟主机自身优势表现也将更加明显,当然,相互之间的竞争也将变得更为激烈。
