This topic describes the compute optimized instance type family with high clock speed hfc5 and the general-purpose instance type family with high clock speed hfg5, and lists the specific instance types within each of these two instance type families.

hfc5, compute optimized type family with high clock speed

Features

  • I/O-optimized
  • Supports SSD Cloud Disks and Ultra Disks
  • Stable performance
  • 3.1 GHz Intel Xeon Gold 6149 (Skylake) processors
  • Equipped with a vCPU to memory ratio of 1:2
  • Supports strong network performance through sufficient computing capacity
  • Suitable for the following scenarios:
    • High-performance Web front-end servers
    • High-performance science and engineering applications
    • Massively Multiplayer Online (MMO) games and video coding
