Manage and Operate ECS – Instance

ECS Instance

An instance is a virtual computing environment, we can call it a virtual machine, which includes CPU, memory, storage, and the other fundamental components required to run a modern operating system.

High Availability

Alibaba Cloud adopts more stringent IDC standards, server access standards, and O&M standards to ensure data reliability and high availability of the cloud computing infrastructure and ECS.

Each Alibaba Cloud region has multiple zones. You can create active/standby or active/active ECS instances in multiple zones to achieve higher availability. You can build fault tolerant systems across multiple regions and zones to implement a financial-grade solution that spans three data centers across two regions. Alibaba Cloud provides mature solutions for fault tolerant services such as disaster recovery.

The Alibaba Cloud framework allows you to seamlessly switch between services. For more information about industry solutions, see Solutions by industry. Alibaba Cloud industry solutions support a variety of services, such as finance, e-commerce, and video services.

Alibaba Cloud provides you with the following support services:

  • Products and services for availability improvement, such as Elastic Compute Service (ECS), Server Load Balancer (SLB), Relational Service (), and Data Transmission Service (DTS).
  • Industry partners and ecosystem partners that help you build a more advanced and stable architecture and guarantee service continuity.
  • Diverse training services that help you achieve high availability from businesses to underlying services.


Alibaba Cloud has passed a host of international information security certifications, such as ISO 27001 and MTCS, which demands strict confidentiality of user data and user information, as well as user privacy protection.

We recommend that you use ECS in a Virtual Private Cloud (VPC). VPCs provide a stable, secure, controllable network environment that can be delivered in a short period of time. The capability and architecture of VPC hybrid cloud bring the technical advantages of cloud computing to enterprises in traditional industries that have not implemented cloud computing.
