As the world's leading transportation platform, traditional IT architectures can no longer meet the rapid growth of DiDi's business needs. Embracing cloud native is the way to go.

We will describe the evolution of our cloud platform; the challenges with scheduling and isolation; the difficulties of containerization; and our technological breakthroughs.
