Business challenges

The Oracle RAC databases on which the company deploys its core ticket management systems for all outlets run on minicomputers. As a result, the data cannot be moved to Alibaba Cloud. However, this company deploys all of its applications on Alibaba Cloud. This hybrid architecture results in high latency that compromises the service availability and performance at peak hours.

The company has limited O&M personnel and needs to outsource technical services to maintain the Oracle databases every year. The company also needs to pay for software licenses from Oracle each year.


Use Advanced Database & Application Migration (ADAM) to move data from Oracle RAC databases to Alibaba Cloud by automatically analyzing and adjusting business-related code based on the specific scenario and process.

Use PolarDB for Oracle to replace Oracle RAC databases. PolarDB for Oracle provides higher performance and can reuse 90% code from Oracle RAC databases. This simplifies the processes of migrating data from Oracle services.


After the Oracle RAC databases are replaced by using ADAM and PolarDB for Oracle, the system availability of the company is significantly improved, and the structure of IT costs is optimized. IT costs are greatly reduced as the company no longer needs to purchase licenses from Oracle.

  • Applications and databases are both deployed on the cloud. This allows the company to flexibly scale cloud resources and minimize network latency. The availability of the business system is also greatly improved.
  • The structure of IT costs is optimized. The company no longer needs to outsource services for Oracle database maintenance or purchase licenses to use Oracle databases. The company needs only to purchase cloud resources on demand.
