This topic describes the hfc5 compute-optimized instance family with high clock speed and hfg5 general-purpose instance family with high clock speed. It also includes information about the instance types that belong to these instance families.

Compute-optimized instance family with high clock speed, hfc5

Features:
  • Optimized I/O performance
  • Supports SSDs and ultra disks
  • Stable computing performance
  • 3.1 GHz Intel ® Xeon ® Gold 6149 (Skylake) processors
  • 1:2 CPU-to-memory ratio
  • Higher network performance along with more computing capacity
  • Scenarios:
    • High-performance Web frontend servers
    • High-performance scientific and engineering applications
    • Massive multiplayer online (MMO) gaming and video coding
The following table describes the instance types that belong to the hfc5 instance family and specifications of these instance types.
