Didi is a ridesharing company similar to Uber, which was founded in 2012, but right now Didi is providing transportation services for close to 400 million users across over 400 cities in China. As the infrastructure team, we faced a wide range of technical challenges:
- With a 500% annual requests growth, how to guarantee the service quality for a rapidly expanding system?
- With more than 400 releases per day, how to ensure to iterate applications rapidly and minimize risk?
- How to prevent a large scale system failure, which will immediately affect customers over 400 cities?
- How to put as much efforts as we could into the system stability along with rapidly business iteration
In this session, we will share lessons learned from Didi:
- The importance of a specific stress test and system capacity estimation for our ridesharing service.
- The best practice of Didi’s standard delivery including application requirements and deployment procedure.
- The benefits from an intelligent load balancing strategy based on cities and a high availability system which across different region zones.
- A measurement mechanism for system stability work.
