Cloud Native

Quickly build a cloud-native microservice system and develop more reliable, scalable and easy-to-maintain cloud-native applications.

"Over the past three years, Bytedance has witnessed rapid growth in the number and scale of its microservices. In 2018, we had about 7,000-8,000 online microservices, and by May of 2021, the number had exceeded 50,000. Now, we have decided to open source these technologies to help more developers. "
