A NSGA-II-based Approach for Multi-objective Micro-service Allocation in Container-based Clouds

Micro-services is a widely adopted architecture to develop large scale web applications. To provide a scalable and low-overhead resource service to micro-service applications, the new container-based clouds are proposed. The new clouds use both containers and VMs to manage resources to achieve a low-overhead, high-utilization data center. However, existing resource allocation approaches either do not consider the dependencies between containers or can only be applied in OS-level container clouds which allocate containers directly to physical machines. To address the multi-objective optimization problem, this work proposes a multi-objective NSGA-II to optimize the availability of applications and the energy consumption requirement of container-based clouds. Our goal is to provide solutions with different tradeoffs between two objectives for cloud providers to choose from. We evaluate the algorithm with a wide range of scenarios by simulation and compare with state-of-the-art algorithms. The results show that our approach significantly outperforms other approaches.
