This topic describes the features of ECS compute optimized instance families and lists the instance types of each family.

c6e, compute optimized instance family with enhanced performance

Features
  • Provides predictable and consistent high performance and reduces virtualization overheads with the use of the third generation X-Dragon architecture. c6e improves storage performance, network performance, and compute stability through fast path acceleration of X-Dragon chips by an order of magnitude.
  • I/O optimized.
  • Supports only enhanced SSDs (ESSDs).
  • Provides high network and storage I/O performance based on large computing capacity.
    Note For more information about the storage I/O performance of the new generation of enterprise-level instance families, see Storage I/O performance.
  • Provides an ultra high packet forwarding rate.
    Note The maximum network performance varies with instance families. For higher packet forwarding rate, we recommend that you use g5ne. For more information, see g5ne, general purpose instance family with enhanced network performance.
  • Offers a CPU-to-memory ratio of 1:2.
  • Equipped with 2.5 GHz Intel ® Xeon ® Platinum 8269CY (Cascade Lake) processors with a maximum turbo frequency of 3.2 GHz.
  • Allows you to enable or disable Hyper-Threading.
    Note By default, Hyper-Threading is enabled on ECS instances. For more information, see Customize CPU options.
  • 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 massively multiplayer online (MMO) games
    • Data analysis, batch processing, and video encoding
    • High-performance scientific and engineering applications

Note
  • You can go to the ECS Instance Types Available for Each Region page to view the instance types available in each region.
  • For more information about these specifications, see Instance specifications.
  • The results for network capabilities are the maximum values obtained from single item tests. For example, when network bandwidth is tested, no stress tests are performed on the packet forwarding rate and other specifications.
