Instance Specification Types

Last updated：2024-09-11 10:44:54

Overview

According to the business usage scenarios, instances can be divided into various instance specification families. Each specification family adopts different processors, CPU/memory ratios, cloud disk types, network card virtualization methods, etc., providing differentiated computing, storage, and network performance. Different instance specification families represent different instance types.

• According to different system architecture types, instance specification families can be divided into x86 computing, elastic bare-metal, and heterogeneous computing.
• According to different business usage scenarios, instance specification families can be divided into general-purpose, compute-optimized, memory-optimized, big data, etc.

Instance Specification Family Names

Format: <Instance specification family type><number>

• Instance specification family type: represented in lowercase English letters, and the meaning of some lowercase letters are as follows.
  • gc: General computing, general-purpose
  • ec: Elastic computing, compute-optimized
  • rc: Memory-Optimized computing, memory-optimized
• Number: represents the generation of specification family. Typically, the larger the number, the newer the generation of specification family.

Instance Specification Names

Format: <Instance specification family identifier><Processor label>.<nx>large

• Instance specification family identifier: Same as above.
• Processor label: Represented in lowercase English letters, representing the processor manufacturer.
  • i: Intel processor
  • a: AMD processor
• nx: The larger the n, the more vCPU cores.
  • n=0, represents 2 vCPU cores
  • n=1, represents 4 vCPU cores
  • n=2, represents 8 vCPU cores
  • And so on...

Instance Type List
