什么是云服务器
云服务器是基于云计算平台，利用虚拟化技术（比如KVM）将数据中心三大核心要素（计算、网络和存储）进行整合，是一种简单高效、安全可靠、处理能力强的可弹性伸缩的计算服务。
Cloud servers are based on cloud computing platforms, utilizing virtualization technologies (such as KVM) to integrate the three core elements of data centers (computing, network, and storage). They are a simple, efficient, secure, reliable, and highly scalable computing service with strong processing capabilities.

高可用网络High availability network
第八云采用动态BGP网络，其拥可用性高达99.95%，数据中心分布在全国四大区域，覆盖面广。 动态BGP根据设定的寻路协议第一时间自动优化网络结构，以保持客户使用的网络持续稳定、高效。
The Eighth Cloud adopts a dynamic BGP network, with a high availability of 99.95%. The data centers are distributed in the four major regions of the country, with a wide coverage. Dynamic BGP automatically optimizes the network structure based on the set routing protocol in the first time to maintain the continuous stability and efficiency of the network used by customers.
动态BGP有如下特点：
Dynamic BGP has the following characteristics:
- 智能选路：服务器只需要设置一个IP地址，核心路由器根据路由跳数与其它技术指标来确定访问路径，不会占用服务器的任何系统资源。服务器的上行路由与下行路由都能选择合适的路径。
- Intelligent routing: The server only needs to set an IP address, and the core router determines the access path based on route hops and other technical indicators, without occupying any system resources of the server. The server can choose suitable paths for both uplink and downlink routing.
- 链路冗余：由于BGP协议本身具有冗余备份、消除环路的特点，所以当云服务商有多条BGP互联线路时可以实现路由的相互备份，在一条线路出现故障时路由会自动切换到其它线路。
- Link redundancy: Due to the characteristics of redundant backup and elimination of loops in the BGP protocol, when cloud service providers have multiple BGP interconnection lines, they can achieve mutual backup of routes. When one line fails, the route will automatically switch to other lines.
- 无限扩展：使用BGP协议还可以使网络具有很强的扩展性，可以将网络与其他运营商互联，轻松实现单IP多线路，做到所有互联运营商的用户访问都很快。
- Unlimited scalability: The use of BGP protocol can also make the network highly scalable, allowing it to connect with other operators and easily achieve single IP and multiple lines, achieving fast user access for all interconnected operators.
