Unleashing the Scalability Potential of Power-Constrained Data Center in the Microservice Era
Xiaofeng Hou, Jiacheng Liu, Chao Li, Minyi Guo · 2019
Recent scale-out cloud services have undergone a shift from monolithic applications to microservices by putting each functionality into lightweight software containers. Although traditional data center power optimization frameworks excel at per-server or per-rack management, they can hardly make informed decisions when facing microservices that have different QoS requirements on a per-service basis. In a power-constrained data center, blindly budgeting power usage could lead to a power unbalance issue: microservices on the critical path may not receive adequate power budget. This unavoidably hinders the growth of cloud productivity.
