    CVM Overview

    Tencent Cloud Virtual Machine (CVM) is a scalable cloud computing service that frees you from estimation of resource usage and upfront investment. With Tencent Cloud CVM, you can start CVMs and deploy applications immediately.
    You can customize all resources of a CVM instance, including CPU, memory, disk, network, and security policies. You can also easily adjust the resources in response to any change in demand.

    Using CVM instances

    You can configure and manage CVM instances in the following ways:

    • Console: a web-based UI for configuring and managing CVM instances.
    • API: Tencent Cloud also provides APIs for configuring and managing CVM instances. For more information, see API Category.
    • SDK: you can use SDK or Tencent Cloud CLI to call CVM APIs.
