China Gateway
China Gateway


  • If you want to develop your business in China, you have to deal with data synchronization between different locations. Long physical distances and inadequate cross-border network capabilities may lead to severe data access latency and lousy user experience.

    So how do we ensure low latency synchronization of merchandise data and transaction data between different countries required by your business?

Our Solution

  • Alibaba Cloud Data Transmission Service (DTS) supports ultra-low latency data synchronization of databases between nodes in different locations to ensure high business availability.

    According to our test data, it allows for up to 3884TPS and 15500QPS transfer between the US West (Silicon Valley) and China East (Hangzhou) nodes with an average network latency of only 175ms.

    Ultra-fast data transfer helps users save on wait time and boosts your business' development in China, making distance an issue of the past.


  • With rapid business growth, the requests for data read and write requests will increase at least ten times. This is a big challenge for database performance. If database capabilities are not upgraded, serious issues may affect your business, for example, a server may breakdown due to access overloads.

Our Solution

  • To tackle this challenge, Alibaba Cloud supports read-only instances for better database performance and mitigating your business pressure. The free Automatic Read/Write Splitting technology that splits SQL requests and manages load balancing automatically.

    This automation eliminates the need to modify or decipher read/write layers and eliminates high cost and latency issues. No extra fee for Automatic Read/Write Splitting function if you have read-only instances, thus helping your business developing fast.
