Last updated: 2022-05-18 14:28:48

    Overview

    This document guides you through how to create a Tencent Cloud Virtual Machine (CVM) instance using the custom configuration mode as an example.

    Prerequisites

    Before creating a CVM instance, you need to complete the following steps:

    Directions

    1. Log in to Tencent Cloud. Choose Products -> Compute -> Cloud Virtual Machine. Click Get Started to access the CVM purchase page.
    • Custom Configuration: It is suitable for use in specific scenarios and makes it easier for you to purchase CVM instances for your specific needs.
    1. Configure the following information as prompted by the page:

      CategoryRequired/OptionalConfiguration Description
      Billing MethodRequiredSelect based on actual needs:
      • Pay-As-You-Go: a flexible billing method suitable for scenarios such as e-commerce flash sales where the demand fluctuates sharply and suddenly.
      • Spot Instance: a new instance operation mode suitable for scenarios such as big data computing, online businesses with load balancing, and website services. The general price range is 10%-20% of pay-as-you-go instance.
      For more information on billing methods, please see Billing Method Description.
      Region/Availability ZoneRequired
      • Region: we recommend you select the region closest to your customers to reduce access latency and increase access speed.
      • Availability zone: please select based on your actual needs.
        If you want to purchase multiple CVMs, we recommend you select different availability zones to implement disaster recovery.
      For more information on regions and availability zones, see Regions and Availability Zones.
      NetworkRequiredA logically isolated network space built in Tencent Cloud. A virtual private cloud (VPC) includes at least one subnet. The system provides a default VPC and subnet for each region.
      If the existing VPC or subnet does not meet your requirements, you can create a VPC or subnet on the VPC console.
      Note:
      • Resources in the same VPC can be shared within the private network.
      • When purchasing the CVM, ensure that the CVM and the subnet where the CVM is created have the same availability zones.
      InstanceRequiredTencent Cloud provides different instance types based on the underlying hardware. For optimal performance, we recommend you use instance types of the latest generation.
      For more information on instances, see Instance Types.
      ImageRequiredTencent Cloud provides public images, custom images, shared images, and marketplaces. For more information about images, see Image Types.
      System DiskRequiredUsed to install the operating system. Its default capacity is 50 GB.
      Available Cloud Block Storage (CBS) types vary with regions. Please select a value as instructed by the page.
      For more information on CBS, see Cloud Disk Types.
      Data DiskOptionalUsed to scale up the storage capacity of the CVM to ensure high efficiency and reliability. CBS data disks are not added by default.
      For more information on CBS, see CBS Types.
      Scheduled SnapshotOptionalA scheduled snapshot policy can be set for the system disk or data disk. For more information, see Scheduled Snapshot.
      Public Network BandwidthRequiredBy default, a dedicated public IP will be assigned for free.
      Tencent Cloud provides two network billing modes. Configure a value greater than 0 Mbps as needed.
      • Bill-by-bandwidth: select a fixed bandwidth. Packet loss will occur when the bandwidth exceeds this value. This is applicable to scenarios where the network connection fluctuates slightly.
      • Bill-by-traffic: billing is based on traffic that is actually used. You can specify a peak bandwidth to prevent charges incurred by unexpected traffic. Packet loss will occur when the instantaneous bandwidth exceeds this value. This is applicable to scenarios where the network connection fluctuates significantly.
      • Bill by bandwidth package: select this aggregated billing when your public network instances have traffic peaks at different times. This is applicable to large-scale businesses where traffic can be staggered between different instances using the public network.
        BWP is currently in beta. To try it out, please submit a beta application.
      Note:
      • The assigned free dedicated public IP cannot be unbound from the instance. To unbind this IP address, first convert the public IP to an elastic IP. For more information on elastic IP, see Elastic IP (EIP).
      • A dedicated public IP address cannot be assigned in the following two cases. Please refer to the purchase page for the latest information.
        • The IP resources have been sold out
        • In certain regions
      IPv6 AddressOptionalThe IPv6 address of the activated instance.
      QuantityRequiredNumber of CVMs to be purchased.
      DurationRequiredUsage duration of the CVM instance.
    2. Click Next: Complete Configuration to access the CVM configuration page.

    3. Configure the following information as prompted by the page:

      CategoryRequired/OptionalConfiguration Description
