Item | Required | Description |
Yes | Select one as needed: Pay-as-you-go:It is an elastic billing method of CVM applicable to scenarios such as e-commerce flash sales, where demand will fluctuate significantly in an instant. Spot instance:A novel operational mode for instances, aptly suited for scenarios such as big data computing, and load-balanced online services and website services. As market supply and demand dynamics shift, the price of spot instances fluctuates accordingly, typically ranging from 3% to 20% of the pay-as-you-go price. | |
Region | Yes | Select the region closest to your users to minimize the access latency and improve the access speed |
AZ | Yes | Select one as needed. If you want to purchase multiple CVM instances, we recommend you select different AZs to implement disaster recovery. For more information, see Regions and AZs. |
Instance | Yes | Tencent Cloud provides different instance types based on the underlying hardware. For optimal performance, we recommend you use instance types of the latest generation. |
Image | Yes | Tencent Cloud provides public images, custom images, and shared images. For more information on images, see Image Types. We recommend new Tencent Cloud users select a public image. |
Yes | It is used for OS installation and defaults to 50 GB. Available cloud disk types vary by region. Select one as instructed on the page. | |
No | It is used to scale up the storage capacity of the CVM instance to ensure high efficiency and reliability. It is not added by default. | |
Scheduled Snapshot | No | A scheduled snapshot policy can be set for the system disk or data disk. For more information, see Scheduled Snapshots. |
Quantity | Yes | It indicates the quantity of CVM instances to be purchased. |
Item | Required | Description |
Network | Yes | It is a logically isolated network space built in Tencent Cloud. A 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 in the VPC console. Note: By default, resources in the same VPC are interconnected over the private network. When purchasing a CVM instance, make sure that the CVM instance and its subnet are in the same AZ. |
Public IP | No | If your CVM instance needs to access the public network, you need to assign a public IP for it. You can assign the public IP when creating the CVM instance or configure an EIP after the creation. |
Bill-by-bandwidth mode | No | Tencent Cloud provides two network billing modes. You can select one as needed. 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 mode when your public network instances have traffic peaks at different times. It is applicable to large-scale businesses where traffic can be staggered between different instances using the public network. |
Bandwidth value | No | You can set the maximum public network bandwidth of the CVM instance as needed. For more information, see Public Network Bandwidth Cap. |
Security group | Yes | Used to configure the network access policies for one or more CVM instances. Make sure that login port 22 is open. For more information, see Security Group. |
Tag | No | You can add tags for the CVM instance as needed, which can be used to categorize, search for, and aggregate cloud resources. For more information, see Overview. |
Instance name | No | The name of the CVM to be created. It is user-defined. We recommendCVM-01. |
Login Methods | Yes | Configure the method to log in to the CVM as needed. Set Password: Customize the password for logging in to the instance. SSH Key Pair: Associate the instance with an SSH key to ensure secure login to the CVM. If no key is available or existing keys are inappropriate, click Create Now to create a key. For more information on SSH keys, see SSH Keys. Random Password: A password will be automatically generated and sent to you in Message Center. |
Instance Termination Protection | No | It is not enabled by default. You can enable it as needed. Then, you cannot terminate an instance in the console or via the API. For more information, see Enabling Instance Termination Protection. |
Security enhancement | No | By default, security service is enabled for free to help you build a CVM security system to prevent data leakage. |
Tencent Cloud Observability Platform | No | CM is activated by default. It provides comprehensive CVM data monitoring, smart data analysis, real-time fault alarms, and custom data reports to precisely monitor Tencent Cloud services and the health conditions of CVM instances. |
Automation Assistant | No | It is enabled free of charge by default. As the native Ops and deployment tool of CVM, it can automatically run shell commands in batches and complete various tasks such as running automated Ops scripts, polling processes, installing/uninstalling software, updating applications, and installing patches, without the need to connect to the instance remotely. |
Advanced settings | No | Configure additional settings for the instance as needed. Hostname: You can customize the name of the computer in the CVM operating system. After a CVM instance is created, you can log in to it to view the hostname. Project: The default project is selected. You can select an existing project as needed to manage different CVM instances. CAM Role: You can set a role and use it to grant role entity the permissions to access CVM services and resources and perform operations in Tencent Cloud. For detailed directions, see Managing Roles. Placement Group: You can add the instances to placement groups to improve your business availability. For detailed directions, see Placement Group. Custom Data: You can configure an instance by specifying custom data, and the configured scripts will run when an instance is launched. If multiple CVM instances are purchased together, the custom data will run on all CVM instances. The Linux operating system supports the Shell format and a maximum of 16 KB of raw data. For more information, see Configuring Custom Data (Linux CVM). Note: Custom data configuration only supports certain public images with the Cloud-Init service. For more information, see Cloud-Init. |
