This topic describes the g5 and g6 general purpose instance families, and sn2ne general purpose instance family with enhanced network performance and lists their instance types.

g6, general purpose instance family

Features
  • Provides predictable stable and high performance and reduces virtualization overheads with the use of the X-Dragon architecture
  • I/O optimized
  • Supports enhanced SSDs, standard SSDs, and ultra disks
  • CPU-to-memory ratio of 1:4
  • Ultra high packet forwarding rate
  • Equipped with 2.5 GHz Second Generation Intel ® Xeon ® Scalable processors, up to 3.2 GHz Turbo Boost
  • Provides strong network performance based on sufficient computing capacity
  • Does not support instance upgrades or downgrades
  • Suitable for the following scenarios:
    • Scenarios where large volumes of packets are received and transmitted, such as bullet screen and re-transmission of telecommunication information
    • Enterprise-level applications of various types and sizes
    • Websites and application servers
    • Game servers
    • Small and medium-sized database systems, cache, and search clusters
    • Data analysis and computing
    • Computing clusters and memory-intensive data processing
