    General-purpose instance family g9i

    • Overview: g9i instances are built on the new Cloud Infrastructure Processing Unit (CIPU) architecture and powered by Intel® Xeon® 6 processors with P-cores (performance cores). These instances provide stable computing power, a powerful I/O engine, and chip-level security hardening.

    • Use cases: Ideal for workloads with high packet forwarding rates, game servers, small and medium-sized database systems, caches, search clusters, search and promotion applications, web and application servers, data analytics and computing, and trusted computing scenarios.

    • Compute:

      • Processor-to-memory ratio of 1:4.

      • Processor: Intel® Xeon® Granite Rapids processors with a base frequency of 3.2 GHz, an all-core turbo frequency of 3.6 GHz, and a single-core maximum turbo frequency of 3.9 GHz.

        Note

        The system may display different frequencies for this instance. The single-core maximum turbo frequency of 3.9 GHz represents burst performance that depends on the overall CPU load of the physical machine and is not covered by the Service-Level Agreement (SLA).

      • For information about operating system compatibility, see Intel instance types and operating system compatibility.

    • Storage:

      • These are I/O optimized instances.

      • Supports the NVMe protocol. For more information, see Overview of the NVMe protocol.

      • Supported cloud disk types: ESSD cloud disk, ESSD AutoPL cloud disk, and Regional ESSD. For more information, see Overview of Elastic Block Storage.

      • Smaller instance types feature burstable cloud disk IOPS and bandwidth. Storage I/O performance increases with instance size. For more information, see Storage I/O performance.

    • Network:

    • Security: Supports the Trusted Platform Module (vTPM) feature. For more information, see Overview of trusted computing.

    Note

    • The Packet Forwarding Rate (PPS) varies significantly by use case. We recommend that you stress-test your services to select the appropriate instance type.

    • For ecs.g8a.large and ecs.g8a.xlarge instances, you must enable jumbo frames to achieve the burst network bandwidth of 12.5 Gbit/s. For more information, see Jumbo frames.

    Sn2ne general-purpose network-enhanced instance family

    • Use cases:

      • High Packet Per Second (PPS) workloads, such as Live Comments and telecom service forwarding.

      • Enterprise applications of various types and sizes.

      • Small and medium-sized database systems, Caches, and Search Clusters.

      • Data Analytics and computing.

      • Compute Clusters and memory-intensive data processing.

    • Compute:

      • Processor-to-memory ratio of 1:4.

      • Processor: 2.5 GHz Intel® Xeon® E5-2682 v4 (Broadwell), Platinum 8163 (Skylake), or 8269CY (Cascade Lake) processors, offering stable computing performance.

        Note

        Instances in this family may use different server platforms. If you require a consistent server platform, use g6, g6e, or g7 instances instead.

    • Storage:

      • I/O Optimized instances.

      • Supported Cloud Disk types: Standard SSD and Ultra Disk. For more information, see Overview of Block Storage.

    • Network:

      • Supports IPv4 and IPv6. For information about IPv6 communication, see IPv6 communication.

      • Offers a high Packet Forwarding Rate (PPS).

      • Network performance increases with instance size.
