Elastic Compute Service:Overview of ECS instance families

Last Updated:May 11, 2024

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 purchase 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 consists of multiple instance types that each have a combination of different capacities, including CPU and memory capacities. 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 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 Instance Types Available for Each Region page to view the available instance types in each region.

Enterprise scenarios 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 of x86-based instance types corresponds to a hyperthread of a processor core, whereas each vCPU of Arm-based instance types corresponds to a physical processor core. For 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 select instance families based on scenarios, see Best practices for selecting ECS instance types.

ECS instance families are categorized into the following categories based on their system architecture and use scenarios.

  • You can go to the Instance Types Available for Each Region page to view the instance types available in each region.

  • For more information about these specifications, see the "Instance type specifications" section in Overview of instance families. Packet forwarding rates vary significantly based on business scenarios. We recommend that you perform business stress tests on instances to choose appropriate instance types.

  • Each ecs.g7nex.32xlarge instance must have at least two elastic network interfaces (ENIs) that are assigned different network card indexes before the instance can burst its network bandwidth to 160 Gbit/s. If all ENIs on the instance are assigned the same network card index, the instance can burst its network bandwidth only to 100 Gbit/s. For more information, see AttachNetworkInterface.

re6p, persistent memory-optimized instance family

For answers to commonly asked questions about persistent memory-optimized instances, see Instance FAQ.

Features:

  • This instance family uses Intel® OptaneTM persistent memory.

    Important

    The reliability of data stored in persistent memory depends on the reliability of persistent memory devices and the physical servers to which these devices are attached. This increases the risks of single points of failure (SPOFs). To ensure the reliability of application data, we recommend that you implement data redundancy at the application layer and use cloud disks for long-term data storage.

  • This instance family allows persistent memory to be used as memory or as local SSDs on instances of some instance types.
