什么是弹性云主机? 拥有哪些特点? 弹性云主机可随时在线调整硬件CPU/内存/硬盘及网络配置 What is an elastic cloud host?
The elastic cloud host is the available resources for cloud processing, which can flexibly change the configuration level of users. For example, if you want to upgrade the 1H1G configuration bought by a cloud server, you only need cloud processing. Not limited by traditional hardware equipment.
The elastic cloud server has good scalability, allowing users to flexibly adjust the server's memory, system disk and bandwidth online at any time; relying on the cost advantage of cluster deployment, it greatly reduces the cost of IT deployment and business operation and maintenance; due to decentralized services In multiple hosts, or even multiple computer rooms, it is not easy to complete downtime, and has strong disaster tolerance and fault tolerance. It can ensure long-term online and make website operation safer and more reliable.
Generally speaking, the resource call flexibility of the elastic host, such as flexible adjustment of the increase and decrease of the configuration of the cloud server. The billing method is flexible. When you buy a cloud server, you only pay for the resources you need to use (network, server, storage, etc.) to improve resource utilization efficiency, while avoiding unnecessary waste and optimizing operating costs. The flexibility of business management, in order to calmly cope with the "peaks" and "lows" of traffic, cloud server rental also has the ability to temporarily adapt and scale freely.
What are the advantages of cloud servers?
1 The security is higher. The cloud server is virtualized based on the server cluster through certain technical means, and can freely control the advantage of the idle resources of the cluster server. Even if one of the machines fails, the website can still operate normally.
2 With good scalability, the cloud server can choose to upgrade or reduce the configuration elastically in real time according to the actual needs of the website. Let resources get the maximum use.
3 It is more conducive to website promotion and optimization. The cloud server has independent IP hard disk bandwidth, faster access speed and larger space. Independent IP will not be affected by other user websites, and it is more favored by Baidu spiders and more conducive to search engines. Included!
什么叫弹性云主机?
弹性云主机就是云端处理可利用资源，灵活变化处理用户的配置高低。比如云服务器买的1H1G的配置，想要升级，只需要云端处理就可以了。不受传统硬件设备的限制。
弹性云服务器具有良好的可拓展性，支持用户随时在线对服务器的内存、系统盘和带宽进行灵活调整；凭借集群部署的成本优势，极大程度降低了IT部署与业务运维成本；由于服务分散在多台主机、甚至多个机房，所以不容易彻底宕机，抗灾容错能力强，能够确保长时间在线，让网站运行更加安全、可靠。
一般来说弹性主机的资源调用弹性，比如灵活调整云服务器的增加减少配置。计费方式弹性，而购买云服务器，仅为自己需要使用的资源（网络、服务器、存储等）付费，提高资源利用效率，同时也避免了不必要的浪费，优化了运营成本。业务管理的弹性，为从容应对流量的“高峰”和“低谷”，云服务器租用还具备临时变通、自由伸缩的能力。
云服务器有哪些优点？
1 安全性更高，云服务器是基于服务器集群通过一定的技术手段虚拟出来的，可以自由支配集群服务器闲置资源的优势，即使其中一台机器发生故障，网站仍然可以正常运作。
2 良好的拓展性，云服务器可以跟据网站的实际需求，实时选择弹性升级 或降低配置。让资源得到最大的利用。
3 更有利于网站推广及优化，云服务器具有独立的IP 硬盘 带宽，访问速度更快，空间更大，独立ip不会受其他用户网站的影响，更受百度蜘蛛的青睐及更利于搜索引擎的收录！
