Modern governance and operations

Enterprise cloud migration does not mean modernization of all applications. Instead, old and new applications will coexist for a period of time. Huawei ROMA Connect helps enterprises integrate old and new applications so that they can coexist on the cloud without damaging the existing application environment. The following are some steps and suggestions for reference:

  • Understanding old and new apps: First, you need to have a comprehensive understanding of the existing apps and the new apps to be integrated. This includes understanding their functions, data structures, interfaces, and communication modes. This will help determine the integration strategy and technology selection.
  • Select an appropriate integration method: Select an appropriate integration method based on your requirements and app characteristics. ROMA Connect provides multiple integration methods, such as API integration, message queue, and event trigger. Select the most appropriate integration mode based on the dependency and communication mode between applications.
  • Integration solution design: Design a detailed integration solution based on the application analysis and selected integration mode. This includes defining interface specifications, data mapping, message passing mechanisms, and so on. Ensure that the design solution is compatible with the interaction between the old and new applications and does not interrupt the existing service processes.
  • Integration implementation: Implement the integration based on the integration solution. Use the tools and platforms provided by ROMA Connect to configure and set necessary integration components and connectors. Ensure that key parameters such as data mapping, message route, and security authentication are correctly configured.
  • Perform comprehensive testing and verification before the integration application is put into production. Ensure that the data transfer and function invoking between the old and new applications are normal and no damage or conflict occurs.
  • Perform monitoring and maintenance. Once the integration application goes live, establish a monitoring mechanism to track the running status of the integration environment. The application performance, API availability, and data consistency are monitored. Handle exceptions in time and perform maintenance and optimization periodically.
