An Elastic Compute Service (ECS) instance is a virtual server and the smallest computing service unit in the cloud. An instance type essentially determines the hardware of the host computer used for your instance. Each instance type offers different compute and memory capabilities. This topic describes all ECS instance families available for sale and introduces their features, specifications, and use scenarios.

ECS provides a variety of instance families for different use scenarios or application workloads. Each instance family offers multiple instance types based on their CPU and memory specifications. ECS instance type defines the basic properties of an ECS instance, including CPU (CPU model and 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 applications require high business stability. Alibaba Cloud ECS instance families are categorized 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 an Intel® Xeon® core. For more information about the differences between enterprise-level and shared instance families, see Instance FAQ.

You can upgrade or downgrade instance types within the same instance family or across different instance families. For more information, see Instance families that support instance type changes.

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

Note
  • Intel Ice Lake supports only remote attestation based on Intel Software Guard Extensions Data Center Attestation Primitives (Intel SGX DCAP), and does not support remote attestation based on Intel Enhanced Privacy ID (EPID). You must adapt applications before you can use the remote attestation feature. For more information about remote attestation, see Strengthen Enclave Trust with Attestation.
  • Intel SGX is based on the host hardware. This instance family does not support hot migration.
  • Operations such as changing instance types and enabling the economical mode may cause the host of an instance to change. Changes to the host of an instance of this instance family may cause failures to decrypt data. Proceed with caution.
  • By default, auto failover is disabled. You can enable it. For more information, see Modify instance maintenance attributes. Auto failover causes the host of an instance to change. Changes to the host of an instance of this instance family may cause failures to decrypt data. Proceed with caution.
  • When you create a security-enhanced instance, you must select a dedicated image to use the security features. For more information, see Create security-enhanced instances.
