On the afternoon of August 9, Alibaba Cloud released a new-generation Ecs product line for enterprises, officially announcing that it will provide customers with high-performance, stable, and affordable enterprise-level cloud server products.
At the scene, the powerful infrastructure is one of the key contents of Alibaba Cloud's product director and senior expert Jiang Linquan's interpretation. As we all know, the stability of cloud servers depends to a large extent on the stability of the data center. In daily enterprise applications, problems abound due to the instability of the data center.
So, what is the difference between Alibaba Cloud's data center and data centers of other cloud computing vendors?
On the eve of the press conference, we visited Alibaba Cloud's three data centers in North China to see if we could find the answer.
Alibaba Cloud North China Third Data Center
In Jiang Linquan's view, one of the biggest enemies of a data center is power outage, and Alibaba Cloud's data center adopts two-way independent mains power supply, and dual-circuit protection such as AB-circuit power supply for rack servers allows the data center to cope with ordinary lines In the face of large-scale power outages, the battery backup power supply can seamlessly take over for 25 minutes, and within one minute of the outage, Alibaba Cloud's N+1 redundant diesel generators will quickly start. Ensure user data security.

As a data center, another enemy is the disconnection of the network. A highly available backbone network is also the basis for ensuring enterprise-level ECS. Alibaba Cloud's backbone network has: low-latency, high-speed interconnection between AZs, and dual-redundant network architecture within an AZ. Features such as IDC 3 routing and export fiber redundancy minimize the chance of network disconnection.
North China Three--Route Exit Fiber Redundancy
With years of technical accumulation within Alibaba Group, Alibaba Cloud's data center has the capability of 3+N ultra-multi-line access to BGP . When the operator's exit fails, remote disaster recovery is automatically performed. During the switching process, users cannot perceive In the event of packet loss, availability is greatly improved, and at the same time, it supports disaster recovery between operators, with higher reliability and better quality assurance. The average BGP delay is less than 40ms, and the average packet loss rate is less than 1%
不同运营商的终端客户通过各自运营商网络直接触达阿里云，除传统三大运营商外，还有丰富的小运营商BGP出口。
阿里云宣称通过上述的基础能力建设，阿里云的数据中心机房历史运行可用性达到99.999%，笔者认为是可信的。而在软件上，阿里云拥有自研的飞天超大规模通用计算操作系统，具备百万级服务器智能化运维能力，虚拟化核心技术，通过硬件稳定+软件稳定，打造了一副ECS的钢筋铁骨，保障了企业级ECS的极致稳定。
