On May 15, the Intime Department Store’s database team celebrated the first anniversary of migrating databases to the cloud. According to Intime’s database director, Li Yabo, post migrating Intime’s core business system databases to Alibaba Cloud PolarDB, they were able to support more than 3x traffic at the same cost.

In the four years of new retail, Intime witnessed a digital transformation to become an internet department store, with its architecture deployed in the cloud. During this process, it migrated its databases to the cloud to better support rapid business development.

As a retail enterprise, Intime has been using traditional commercial databases since its establishment, and its core business system is tightly bound to these databases. However, as it transformed into a new retail enterprise, its traditional databases could not expand fast enough to keep pace with business development.

The process of expanding a traditional database cluster is very complex. Intime needed to purchase hardware and deploy a network by itself, so the costs were high. In addition, professional database administrators (DBAs) were required to scale-out nodes, which involves a high degree of risk. After wide-ranging and detailed research, Intime decided to migrate all its businesses to Alibaba Cloud’s PolarDB.

“New retail enterprises such as Intime hold many promotional events each year, during which many database resources are consumed. Therefore, they have very high requirements for stability,” said Li Yabo. After migrating databases to the cloud, Intime could take advantage of the elastic scaling capabilities of PolarDB during promotional events. Today, Intime’s transaction peak has increased 20 times over, but its IT costs have not increased.

PolarDB is designed with separated storage and computing as well as integrated software and hardware. It quickly scales up and down to meet the needs of all large-scale business scenarios. In July 2019, Alibaba Cloud PolarDB was upgraded to be deeply compatible with Oracle syntax and data types, supporting one-click migration of databases to the cloud.

During the 2019 Double 11 Shopping Festival, PolarDB set a new record by completing 87 million database transactions per second (TPS). To date, more than 400,000 database instances have been migrated to Alibaba Cloud, including the databases of leading enterprises across fields such as government affairs, retail, finance, telecommunications, manufacturing, and logistics.

The shift from traditional commercial databases to cloud databases seems to be an inevitable trend. According to Gartner, an authoritative market research institution, cloud databases are the future. By 2021, it is estimated that cloud databases will account for 50% of the total database market, and, by 2023, 75% of databases will run on cloud platforms.
