An Elastic Compute Service (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, including their features, specifications, and application scenarios.

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 visit 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. Each vCPU in an enterprise-level instance family corresponds to a hyperthread of the 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 an 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.

Alibaba Cloud ECS instance families are divided into the following categories based on the system architecture and usage scenarios.

hfc6, compute optimized instance family with high clock speeds

Features
  • Offloads a large number of virtualization features to dedicated hardware with the use of the SHENLONG architecture to provide predictable and consistent ultra-high performance and reduce virtualization overheads.
  • Compute:
    • Offers a CPU-to-memory ratio of 1:2.
    • Uses 3.1 GHz Intel® Xeon® Platinum 8269 (Cascade Lake) processors that deliver a turbo frequency of 3.5 GHz for consistent computing performance.
      Note The CPUs used by this instance family have a clock speed of 3.1 GHz. The Intel System Studio (ISS) feature may cause a lower clock speed to be displayed. Alibaba Cloud is working on this issue. This issue does not affect the actual clock speeds of your instances.
