    Deployment

    Physical resources are shared, but instances are logically isolated.

    Physical resources are exclusively used. The performance of an instance is not affected by other instances. You can select different specifications based on your requirements.

    QPS

    2,000 requests can be sent to a shared instance per second.

    The value fluctuates based on the QPS setting selected during the instance's creation.
