CVM is a flexible and scalable cloud computing service that eliminates the need for upfront investment and resource usage estimation. With CVM, you can quickly launch virtual machines and deploy applications on demand.
Each CVM instance offers full customization — including CPU, memory, storage, network settings, and security configurations — allowing you to tailor resources to your specific needs. You can also scale resources effortlessly to adapt to changing workloads or business requirements.
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: Converge Cloud also provides APIs for configuring and managing CVM instances. For more information, see API Category.
- SDK: You can use SDK or Converge Cloud CLI to call CVM APIs.
CVM Use Cases
- Streaming media applications for images and videos: CVMs allow you to deploy streaming applications with custom configurations and scale them based on traffic demand, ensuring a seamless viewing experience.
- Development & Testing Environments: Quickly spin up isolated environments for development and testing purposes.
- Small-scale web/app applications and internal corporate websites: Host lightweight applications and internal portals with ease.
CVM Instance Configuration
Key Concepts
1. Instance
A virtual computing resource containing basic computing components such as CPU, memory, OS, network, and disks. Converge Cloud provides various configurations of CPU, memory, storage, and networking capacity for CVM instances. For more information, please see Instance Types.
2. Image
A pre-configured template containing an operating system and applications that CVM instances run on. Converge Cloud CVM provides pre-configured images for Windows, Linux, and other operating systems.
3. Cloud Block Storage
A distributed and persistent block storage device provided by Converge Cloud that can serve as the system disk or an expandable data disk of an instance.
4. Virtual Private Cloud
A logically isolated virtual network space in Converge Cloud.
5. IP Address
Converge 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.
6. Elastic IP
Static public network IP addresses designed especially for dynamic networks to meet the demands for fast troubleshooting.
7. 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.
