Tackle the challenges of real-time data synchronization between China and the world with global data transfer within milliseconds

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?

Alibaba Cloud's 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.

Develop your business: Helps you save time & zero additional cost

With rapid business growth, data read and write requests— mainly read requests—will increase at least ten times; this seriously challenges database performance. If database capabilities are not upgraded, serious issues may affect your business, for example, a server may breakdown due to access overloads.

To tackle this challenge, Alibaba Cloud supports the use of read-only instances to promote database performance and mitigate business pressure. Alibaba Cloud also provides 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.

Most importantly, you do not need to pay extra money to use Automatic Read/Write Splitting only if you have read-only instances, thus helping your business developing fast.
