This topic describes the compute optimized instance families and their instance types.

ic5, compute intensive instance family

Features
  • I/O optimized
  • Supports enhanced SSDs, standard SSDs, and ultra disks
  • CPU-to-memory ratio of 1:1
  • Ultra high packet forwarding rate
  • Equipped with 2.5 GHz Intel ® Xeon ® Platinum 8163 (Skylake) or 8269CY (Cascade Lake) processors

c6, compute optimized 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 c6 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
  • Supports enabling or disabling Hyper-Threading
    Note By default, Hyper-Threading is enabled on ECS instances. For more information, see Customize CPU options.
  • CPU-to-memory ratio of 1:2
  • Ultra high packet forwarding rate
  • 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 g6 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
    • Web frontend servers
    • Frontend servers of massive multiplayer online (MMO) games
    • Data analysis, batch compute, and video encoding
    • High-performance science and engineering applications
