• Development Framework

  For architecture selection, the business has strong consistency (such as in the financial industry and e-commerce), and spring cloud is generally not used. In some cases, spring cloud may have some inconsistencies in order to meet high availability requirements. Dubbo is a good choice for architecture selection for strongly consistent business.

  • spring (spring cloud/restful)
    • Spring Foundation
    • Spring Advanced
  • dubbo (rpc)

    Refer to the official websitehttp://dubbo.apache.org/ (opens new window)
