    Background information

    Before you read further in this topic, you must be familiar with the following information:

    • Classification and naming of instance types. Familiarize yourself with the instance family categories, naming conventions of instance types, and differences between instance families. For more information, see Classification and naming of instance types.

    • Instance type metrics. For information about the metrics of instance types, see Instance type metrics.

    • Instructions for selecting instance types based on your business scenarios. For more information, see Instance type selection.

    After you determine an instance type for your use case, you may need to learn about the following information:

    • Regions in which the instance type is available for purchase. Instance types that are available for purchase vary based on the region. You can go to the Instance Types Available for Each Region page to view the instance types available for purchase in each region.

    • Estimated instance costs. You can calculate the price of instances that uses different billing methods in the Price Calculator.

    • Instructions for purchasing an instance. You can go to the ECS instance buy page to place a purchase order for instances.

    You may be concerned about the following information:

    • Retired instance families. If you cannot find an instance type in this topic, the instance type may be in a retired instance family. For information about retired instance families, see Retired instance families.

    • Supported instance type changes. Before you change the instance type of an instance, check whether the instance type can be changed and identify compatible instance types. For more information, see Instance types and families that support instance type changes.

    Note

    • 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 or other network metrics.

    g6, general-purpose instance family

    • Introduction: This instance family offloads a large number of virtualization features to dedicated hardware by using the SHENLONG architecture to provide predictable and consistent ultra-high performance and reduce virtualization overheads.

    • Supported scenarios:

      • Scenarios where large volumes of packets are received and transmitted, such as live commenting on videos and telecom data forwarding

      • Enterprise-level applications of various types and sizes

      • Websites and application servers

      • Game servers

      • Small and medium-sized database systems, caches, and search clusters

      • Data analytics and computing

      • Computing clusters and memory-intensive data processing

    • Compute:

      • Offers a CPU-to-memory ratio of 1:4.

      • Uses 2.5 GHz Intel® Xeon® Platinum 8269CY (Cascade Lake) processors that deliver a turbo frequency of 3.2 GHz to provide consistent computing performance.

      • Supports Hyper-Threading. By default, Hyper-Threading is enabled. For more information, see Specify and view CPU options.

    • Storage:

      • Is an instance family in which all instances are I/O optimized.

      • Supports ESSDs, ESSD AutoPL disks, standard SSDs, and ultra disks. For information about disks, see Overview of Block Storage.

        Note

        The maximum performance of disks varies based on the instance families. A single instance of this instance family can deliver up to 200,000 IOPS.

      • Provides high network and storage I/O performance based on large computing capacity. For more information, see Storage I/O performance.

    • Network:

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

      • Provides ultra-high packet forwarding rates.

        Note

        Network performance varies based on the instance families. For higher concurrent connection and network packet forwarding capabilities, we recommend that you use the g7ne instance family.

      • Provides high network performance based on large computing capacity.

    • Supported instance type changes: Supports changes to c6 or r6 instance types.

    The g6 instance family includes the following instance types: ecs.g6.large, ecs.g6.xlarge, ecs.g6.2xlarge, ecs.g6.3xlarge, ecs.g6.4xlarge, ecs.g6.6xlarge, ecs.g6.8xlarge, ecs.g6.13xlarge, and ecs.g6.26xlarge.
