ic5, compute-intensive instance family

Features
  • Compute:
    • Offers a CPU-to-memory ratio of 1:1.
    • Uses 2.5 GHz Intel® Xeon® Platinum 8163 (Skylake) or 8269CY (Cascade Lake) processors for consistent computing performance.
  • Storage:
    • Is an instance family in which all instances are I/O optimized.
    • Supports ESSDs, standard SSDs, and ultra disks.
  • Network:
    • Provides ultra-high packet forwarding rates.
    • Provides high network performance based on large computing capacity.
  • Applicable scenarios:
    • Web frontend servers
    • Data analysis, batch compute, and video encoding
    • Scenarios where large volumes of packets are received and transmitted, such as on-screen video comments and telecom data forwarding
    • Frontend servers of MMO games
