Compared with CVM, Lighthouse is easier to use and more suitable for SMEs, developers, cloud computing beginners, and students, as it simplifies CVM's advanced concepts and features. It offers high-bandwidth data transfer plans and integrates basic cloud services into cost-effective bundles. Such bundles contain popular open-source software programs perfect for lightweight use cases with low to medium load and moderate access requests, such as small and mid-sized websites, web applications, blogs, forums, mini games, ecommerce, cloud storage, and image hosting, as well as development, testing, and learning environments in the cloud.
Note
- When creating a Lighthouse instance, you cannot specify the CPU model of the underlying physical server; instead, Tencent Cloud will randomly assign a physical CPU model that meets the selected bundle specification.
- At the same specification level, Lighthouse has a CPU and memory performance comparable with that of CVM.
The table below lists Lighthouse's strengths and main differences from CVM:
Product Strength |
Lighthouse | CVM | |
|---|---|---|---|
| Target user | SMEs and individual developers | Large enterprises | |
| Lightweight scenario-oriented | Lightweight use cases:
|
Use cases with complex architectures:
|
|
| Favorable pricing | Selling method | Cost-effective bundles (combinations of computing/network/storage resources) | Flexible selection of computing/storage/network resources that are billed independently |
| Network billing | High-bandwidth data transfer plan | Fixed bandwidth/traffic usage | |
| Simpler use | Console operation | Integrated, independent, and simplified console | For all services, with more details of CVM, VPC, EIP, and security group involved |
| Application creation |
|
Application creation on your own | |
| Networking | Automatic network resource creation without manual management needed | Network creation, configuration, and management on your own | |
Note
- Compared with CVM, the main limits of Lighthouse at the functional level include the following:
An instance supports the overall upgrade of the configuration (computing, storage, and network) on a bundle basis but not bundle downgrade. For more information, see Upgrading Instance Bundle.
For the specific use limits of Lighthouse, see Use Limits.- There are certain limits on private network connectivity for Lighthouse. For more information, see Region and Network Connectivity.
- Lighthouse cloud disks are independent of CVM cloud disks, which means Lighthouse cloud disks can only be attached to Lighthouse instances but not CVM instances.
For scenarios like high-concurrency websites, video encoding/decoding, large-scale games, and complex distributed cluster applications, it's recommended to use CVM. CVM provides rich instance models, such as Memory Optimized, High I/O, Big Data, Bare Metal, and GPU/FPGA Heterogeneous Computing. For more information, see CVM Instance Types.
