随着国内外电商网站的不断发展,虚拟建站服务越来越受到站长的青睐,而说起建站不得不提起开源程序,可以说开源一键安装程序给我们带来更多便捷。最近互联网巨头Google也宣布开源部分数据中心技术,以更好地推动容器虚拟化技术在数据中心内部的使用。
此次Google宣布了两项技术开源,分别是Kubernetes和cAdvisor,Kubernetes有助于开发者调度和管理Google云中使用容器技术部署的虚拟机,并帮助开发者在部署容器技术时少犯错误,不过这项技术在Google数据中心已经使用多年,这里可通过Google的LMCTFY或者Docker容器库来收集采用容器虚拟化技术的工作负载数据。
Google对其数据中心的硬件技术十分保密,但在软件方面相对积极很多。不管是Google还是Amazon,都在数据中心领域都积累了大量的技术和丰富的经验。但在公有云市场表现方面,Google云与AWS却相距甚远,不管是市场占有率还是营收方面,AWS都遥遥领先。
在此之前,Google发起了价格战,几乎在同一时间,AWS和Azure都宣布降价,在业内引起一片热议。尽管Google云在成本方面有一定的优势,但仍不足以让其在短期内追赶上AWS。Google迫切需要培养一个广阔的用户市场,开源数据中心技术可能是一个不错的策略。
与此同时,处于Tier 2的厂商希望“力争上游”这是很常见的,包括IBM也不例外,通过收购SoftLayer,原来还在公有云市场“落后”的IBM一下子进入到Tier 2服务商行列,但作为传统IT解决方案供应商的领头羊当然不会满足,因此最近IBM宣布SoftLayer大幅降价,加入目前AWS、Azure和Google的价格战中。
SoftLayer将对象存储的价格降至每月0.04美元/GB,而Google云同类产品目前的价格是0.026美元,AWS为0.03,Azure则为0.05。从这点上看,SoftLayer的价格还是很有吸引力的。而纵观全球6大公有云供应商,已经有4家加入价格战当中了。
尽管价格战如火如荼,但价格本身不再是决定因素。除了降价之外,IBM也提供了一些额外的特色服务。例如添加了一个名为“Direct Link”的连接选项,其允许SoftLayer用户创建私有云,并从IBM全球的18个网络节点与云建立专用连接,类似微软的Express Route服务和Amazon的Direct Connect服务。
不过SoftLayer的一个潜在优势是全面支持IPv6,亚马逊、谷歌和微软目前尚未全面支持IPv6。物联网和即将出现的海量网络连接设备都必须具有独立的IP地址,因此IP地址的数量十分重要。
