This research follows the trend of latest technology and puts forward a browser‐centric cloud computing service model, termed "cloud service exchange system". This system solves the problem that the requests of the immense volume of data and the request of large data processing from back‐end to the front‐end. In the meantime, this system improves the speed of transmission via buffer. We integrate five elements, including MongoDB, AngularJS, Socket.IO, Kafka, Node.js. This study solves many problems as below: 1. The interaction between JavaScript and web front‐end. 2. The compatibility issues in programing language of front‐end and back‐end. 3. Server overloading caused by the huge amount of information on demand. 4. Instant messaging performance front‐end and back‐end. And finally achieve the goal of creating a website.
