Elastic Compute Service


Elastic Compute Service (ECS) is a high-performance, stable, reliable, and scalable IaaS-level service provided by Alibaba Cloud. It is more convenient and efficient compared with physical servers. You can immediately acquire ECS instances and scale computing resources on-demand. ECS provides a variety of instance types that suit various business needs and help boost business growth.



Alibaba Cloud Elastic Compute Service (ECS) provides fast memory and the latest CPUs to help you to power your cloud applications and achieve faster results with low latency.

Deploy ECS instances with just a few clicks from the easy-to-use console and scale capacity up or down based on real-time demands.


High Availability

Alibaba Cloud ECS provides the highest SLA commitment for both single instance and multiple instances in multiple availability zones among the top cloud providers worldwide. Alibaba Cloud gained lots of experience of running infrastructure at large scale while maintaining high availability. We are currently supporting the world’s largest e-commerce platforms such as Taobao and Tmall and we work closely with scientists from DAMO Academy to accurately predict, prevent and mitigate infrastructure issues without impacting our customers.

Technology Leadership

On top of the world-class customized components from our various vendors, Alibaba Cloud invested heavily on the Research & Development of our ECS product. Over the time, we developed X-Dragon compute platform, including the self-developed SOC, hardware acceleration card, as well as the Dragonfly lightweight hypervisor.Our Technology leadership provides a foundation for the high performance, availability, elasticity, scalability and security you enjoyed in our ECS products.


As the largest cloud provider in China and the 3rd largest cloud provider worldwide by revenue , Alibaba Cloud ECS has the scale to provide high elasticity that can meet your business needs instantly. We can provide hundreds of thousands of vCPUs in minutes for a single customer in a single region, that is because of our sophisticated smart placement algorithm, dynamic and automatic planing as well as our optimization of both hardware and software.
