An ECS instance is the smallest unit that can provide compute capabilities and services for your business. Compute capabilities vary based on instance types. This topic describes available ECS instance families and the features, specifications, and application scenarios of each instance family.

ECS instances are categorized into different instance families based on their usage scenarios. Each instance family is divided into different instance types based on their CPU and memory specifications. ECS instance type defines the basic properties of an ECS instance, such as CPU, clock speed, and memory. In addition to the instance type, you must also configure the Elastic Block Storage (EBS) devices, image, and network type when you create an ECS instance.
Note The available instance families and types vary based on regions. You can go to the ECS Instance Types Available for Each Region page to view the available instance types in each region.

Enterprise scenarios have high requirements for business stability. Alibaba Cloud ECS instance families are divided into enterprise-level and shared instance families based on whether the instance families are suitable for enterprise scenarios. Enterprise-level instance families offer consistent performance and dedicated resources. In enterprise-level instance families, each vCPU corresponds to a hyperthread of the Intel ® Xeon ® core. For more information about the differences between enterprise-level and shared instance families, see ECS instance FAQ.

You can upgrade or downgrade instance types within an instance family or across instance families. For more information, see Change instance types of instances.

For information about how to choose instance families based on scenarios, see Best practices for instance type selection.

Alibaba Cloud ECS instances are categorized into the following instance families:

Enterprise-level computing instance families based on the x86 architecture:
Recommended intance families Other available instance families
Enterprise-level heterogeneous computing instance families:
Recommended intance families Other available instance families
ECS Bare Metal Instance families and Super Computing Cluster (SCC) instance families:
