Elastic Compute Service:Instance families with high clock speeds (hf series)

Last Updated:Nov 15, 2024

Instance families with high clock speeds (hf series) provide CPU-to-memory ratios of 1:2, 1:4, and 1:8 and are suitable for scenarios such as massively multiplayer online (MMO) games, high-performance scientific computing scenarios such as high-performance computing, and large and medium-sized database systems.

Background information

Before you read further in this topic, you must be familiar with the following information:

  • Classification and naming of instance types. Familiarize yourself with the instance family categories, naming conventions of instance types, and differences between instance families. For more information, see Classification and naming of instance types.

  • Instance type metrics. For information about the metrics of instance types, see Instance type metrics.

  • Instructions for selecting instance types based on your business scenarios. For more information, see Instance type selection.

After you determine an instance type for your use case, you may need to learn about the following information:

  • Regions in which the instance type is available for purchase. Instance types that are available for purchase vary based on the region. You can go to the Instance Types Available for Each Region page to view the instance types available for purchase in each region.

  • Estimated instance costs. You can calculate the price of instances that uses different billing methods in the Price Calculator.

  • Instructions for purchasing an instance. You can go to the ECS instance buy page to place a purchase order for instances.

You may be concerned about the following information:

  • Retired instance families. If you cannot find an instance type in this topic, the instance type may be in a retired instance family. For information about retired instance families, see Retired instance families.

  • Supported instance type changes. Before you change the instance type of an instance, check whether the instance type can be changed and identify compatible instance types. For more information, see Instance types and families that support instance type changes.

    • Allows you to enable or disable Hyper-Threading.

      Note

      By default, Hyper-Threading is enabled for ECS instances. For more information, see Specify and view CPU options.

  • Storage:

    • Is an instance family in which all instances are I/O optimized.

    • Supports only ESSDs and ESSD AutoPL disks.

    • Provides high storage I/O performance based on large computing capacity.
