谈谈云计算的5个特性

关于云计算你知道多少?云主机、VPS、虚拟主机那么多的服务器,那么多企业在使用,但是作为根基的云计算,大家似乎认识得不多。今天,要为大家说明关于云计算的5个特性。

谈谈云计算的5个特性

 1、大规模、分布式

  “云”一般具有相当的规模,一些知名的云供应商都拥能拥有上百万级的服务器规模。而依靠这些分布式的服务器所构建起来的“云”能够为使用者提供前所未有的计算能力。

2、高可用性和扩展性

  那些知名的云计算供应商一般都会采用数据多副本容错、计算节点同构可互换等措施来保障服务的高可靠性。基于云服务的应用可以持续对外提供服务(7*24小时),另外“云”的规模可以动态伸缩,来满足应用和用户规模增长的需要。

3、虚拟化

  云计算都会采用虚拟化技术,用户并不需要关注具体的硬件实体,只需要选择一家云服务提供商,注册一个账号,登陆到它们的云控制台,去购买和配置你需要的服务(比如 云服务器,云存储,CDN等等),再为你的应用做一些简单的配置之后,你就可以让你的应用对外服务了,这比传统的在企业的数据中心去部署一套应用要简单方便得多。而且你可以随时随地通过你的PC或移动设备来控制你的资源,这就好像是云服务商为每一个用户都提供了一个IDC(Internet Data Center)一样。

 4、安全

  网络安全已经成为所有企业或个人创业者必须面对的问题,企业的IT团队或个人很难应对那些来自网络的恶意攻击,而使用云服务则可以借助更专业的安全团队来有效降低安全风险。

5、按需服务,更加经济

  用户可以根据自己的需要来购买服务,甚至可以按使用量来进行精确计费。这能大大节省IT成本,而资源的整体利用率也将得到明显的改善。

以上关于云计算的5个特性,正式云服务器那么强大的原因,我们的工作生活也因此在发生改变。

      Healthcare continues to be an formidable, but divisive federal topic. Not surprisingly, 41 percent of suitable voters said healthcare was their critical issue in the mid-term elections in 2018.<a href=http://my-canadianpharmacyonline.com>canadian pharmacy online</a> In 2008, when the ACA became law, only 46 percent of voters supported individual payer healthcare. That army has grown significantly to 59 percent put one's imprimatur on in break of dawn 2018.http://my-canadianpharmacyonline.com canadian online pharmacy While Medicare-for-all legislation is unlikely to pass both the Line and Senate in its progress mould, there is a switch manage in community notion with a solid lion's share promptly in favor.
