Updated:2015/9/21 10:22

On the recently held 2015 New Generation Internet Infrastructure Forum, the director of Alibaba network platform Liu Yang said, Alibaba's ecosystem was very broad, and both private and public cloud coexisted, which has high demands for the network platform.

"Our own business scale is already very large and needs to bear massive services of Alipay, Taobao and others; at the same time, it still carries a large number of public cloud services and at least 1 million developers." Liu Yang said, “In promoting the services to users, the cost is very critical. To the Internet companies like us, whether we can provide the best services with low cost is the key to attract customers in the market."

In reducing the cost, Alibaba has been trying a lot: on the one hand, it tries to cut down the entire hardware costs by using control capabilities of the supply chain and technology progress; on the other hand, it mainly reduce the human costs on the operation/maintenance and R&D costs, “our technologies, operation/maintenance, design, optimization, R&D and others are basically done by ourselves, a lot of costs are precipitated here."

Specifically in the network level, Alibaba mainly focus on three points: big, light and stable. "The so-called big refers to the scale, the number of our physical servers and virtual machines is very big and the bandwidth has expanded from the original 10G to 25G, the bandwidth of the data center also transferred from 10G and 40G to 100G. The other is the time delay, a lot of our applications have very high requirements on the time delay, we made further developments in scale, speed and time delay through the RDMA, NVMe over fabric and other technologies. The second is light, which means virtualized application network and flexible customized topology. The last one is the stable, which is our priority in the considerations. Through stable running and operation and by the visualized first-level automatic discovery and isolation technologies, therefore realizing the rapid responding and problem solving abilities of stable operation." Liu Yang said.
