High Frequency

Overview

High Frequency instances have a processor-to-memory ratio of 1:2, 1:4, or 1:8, offering high-performance computing and high stability. You can use them to efficiently and reliably run large applications. High Frequency instances are applicable for scenarios such as high-performance scientific and engineering applications, data analysis, batch computing, and large-scale multiplayer online games. This topic describes the features, metric data, and applicable scenarios of each instance family of High Frequency instances. By referring to this topic, you can select an instance type that meets your business needs. This helps you ensure that the selected type meets the minimum CPU and memory requirements for your business.
