Data is a source of knowledge. Data science enabled black hole visualization and guerrilla heavy rain prediction. Data services have attracted a huge wealth of data companies such as GAMFA (Google, Apple, Microsoft, Facebook, Amazon) and BATH (Baidu, Alibaba, Tencent, Huawei). In order to produce such results, it is essential to have a basic technology that allows you to store huge amounts of data. We are creating new technologies for such data infrastructure. The new data infrastructure is the driving force for creating new science and services. Since the data infrastructure is sandwiched between applications and devices, we collaborate with researchers and practitioners in a wide range of fields. Would you like to create a wonderful future with us?
