Application Deployment Architecture Survey

The application deployment architecture survey is conducted during the pilot migration or large-scale migration. The survey is based on a single application, and mainly focuses on four layers, that is access layer, application layer, middleware layer, and data layer, of the deployment architecture. The survey also focuses on the detailed information about technical components, such as the specifications, version, and capacity, at each layer. The specific survey content is as follows:

Four Layers of the Application Deployment Architecture

Collect detailed information about the access layer, application layer, middleware layer, and data layer, and collect three types of associations (shared data, shared server, and application interaction communication dependency). You can refer to the following table to collect the details about the deployment architecture of an application.

Figure 2 Survey methods
  1. The CMDB method is preferred.
  2. If CMDB is unavailable, we can also obtain information from the cloud management platform (CMP) or virtualization management software on the live network.
  3. If neither of them (CMDB and CMP) is feasible, we can install an information collection tool (for example, Huawei Cloud RDA) to collect information.
  4. If none of the preceding methods is feasible, we can collect information through interviews.
