This topic describes the general purpose instance families and their instance types.

g6, general purpose instance family

Features
  • Provides predictable and stable high performance and can reduce virtualization overheads with the use of the X-Dragon architecture
  • I/O optimized
  • Supports enhanced SSDs, standard SSDs, and ultra disks
    Note The maximum performance of cloud disks varies depending on instance families. A single g6 instance can deliver an IOPS of up to 200,000. For higher storage I/O performance, we recommend that you use g5se. For more information, see g5se, storage optimized instance family with enhanced performance.
  • Provides strong storage I/O performance with a large computing capacity
  • CPU-to-memory ratio of 1:4
  • Supports enabling or disabling Hyper-Threading
    Note By default, Hyper-Threading is enabled on ECS instances. For more information, see Customize CPU options.
  • Ultra high packet forwarding rate
    Note The maximum network performance varies depending on instance families. For higher packet forwarding rate, we recommend that you use g5ne. For more information, seeg5ne, network enhanced instance family.
  • Equipped with 2.5 GHz Intel ® Xeon ® Platinum 8269CY (Cascade Lake) processors, up to 3.2 GHz Turbo Boost
  • Provides strong network performance with a large computing capacity
  • Supports instance type changes to c6 or r6
  • Suitable for the following scenarios:
    • Scenarios where large volumes of packets are received and transmitted, such as on-screen video comments and telecom data forwarding
    • Enterprise-grade applications of various types and sizes
    • Websites and application servers
    • Game servers
    • Small and medium-sized database systems, caches, and search clusters
    • Data analysis and computing
    • Computing clusters and memory-intensive data processing
