    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.

    Key Concepts

    Before using Tencent Cloud CVM, you should familiarize yourself with the following concepts:

    Instance A virtual computing resource containing basic computing components such as CPU, memory, OS, network, and disks. Tencent Cloud provides various configurations of CPU, MEM, storage, and networking capacity for CVM instances. For more information, please see Instance Types.
    Image A pre-configured template containing an operating system and applications that CVM instances run on. Tencent Cloud CVM provides pre-configured images for Windows, Linux, etc.
    Cloud Block Storage A distributed and persistent block storage device provided by Tencent Cloud that can serve as the system disk or an expandable data disk of an instance.
    Virtual Private Cloud A logically isolated virtual network space in Tencent Cloud.
    IP address Tencent Cloud provides Private IP and Public IP addresses. Private IP addresses are for the interconnection of CVM instances within the same LAN, while public IP addresses are for public-facing services.
    Elastic IP Static public network IP addresses designed especially for dynamic networks to meet the demands for fast troubleshooting.
    Security group A virtual firewall that features stateful data packet filtering. It is used to configure the network access control of CVMs. Security groups are an important measure for network security and isolation.
