　 What is the Aliyun server 　 advantage?

Cloud Server ECS has the advantage of not having traditional servers and virtual hosts:

Stability: Service availability up to 99.95%, data reliability up to 99.99%. Support for downtime migration, data snapshot backup and rollback, and system performance alerting.

Disaster Recovery backup: Multiple copies of each data, a single damage can be quickly recovered in a short period of time.

Security: Supports the configuration of security group rules, Cloud Shield anti-DDOS system, multiuser isolation, password-proof cracking.

Multi-line access: An optimal routing algorithm based on the Boundary Network Management Protocol (Border Gateway PROTOCOL,BGP). BGP multi-line machine room, the national access smooth balance. Backbone room, the export of large bandwidth, exclusive bandwidth.

Flexible expansion: 10 minutes can start or release 100 ECS instances of cloud server, Support online non-stop upgrade bandwidth, 5 minutes downtime upgrade CPU and memory.

Low cost: No need for one-time large investment, on-demand purchase, flexible pay, flexible response to business changes.

Controllability: As a cloud server ECS user, you have Super Administrator privileges, can fully control the cloud server ECS instance of the operating system, you can manage the Terminal self-service solution system problems, and can be deployed environment, installation software and other operations.

Ease of use: rich operating systems and applications, using mirrors to easily deploy the same image with a single key, rapid replication of environments in multiple ECS instances, easy expansion, support for custom mirroring, disk disk snapshots bulk creation cloud Server ECS instances.

API interface: The use of ECS API call management, through the security group features to one or more servers to access settings, so that the development of the use of more convenient.
