Instance type families

Last Updated: Apr 18, 2018

An ECS instance is the minimal unit that can provide computing capabilities and services for your business.

ECS instances are categorized into multiple specification types, which are called type families, based on the business and scenarios. You may select various type families for one business scenario. Each type family contains multiple instance types with different CPU and memory specifications.

Note:
The availability of instance type families and their types varies according to the regions and the amount of resources. Go to the purchase page to check the available instance types.

Two basic attributes define an ECS instance type: the specifications of the CPU, including CPU model and clock speed, and the memory. However, the attributes of a disk, an image, and the network service of an ECS instance must also be defined simultaneously for the specific service type of the instance to be determined.

Alibaba Cloud ECS instances are categorized into the following type families according to the hardware release and business scenarios:

The latest type families

All ECS instances of the latest type families are I/O-optimized. They support the following disk types:

  • SSD Cloud Disks
  • Ultra Cloud Disks

Instances of the latest type families are categorized into the following type families based on business scenarios.

Type families for enterprise-level computing on the x86-architecture

Type families for enterprise-level computing feature stable performance and dedicated resources. For enterprise-level instances, each vCPU core is supported by one Intel Xeon CPU core through hyper-threading.
