Modeling and optimizing micro-service based cloud elastic management system

Cloud elasticity is a comprehensive solution that takes into account all running applications and resources, including the cloud management system. Cloud resources and applications are constantly changing in terms of capacity and behavior, implying a dynamic change in the architecture and characteristics of the cloud management system. Following the micro-service architecture pattern, the new trend in application modeling is to decompose it into components and make them standalone cooperated modules. By customizing the application operation modules to match new tasks, this design provides the application with rapid adaptation agility to changes in requirements. This paper proposes a full-stack micro-service-based elastic cloud management system that elastically scales and manages cloud resources. The proposed model focuses on the elastic scaling performance of micro-service management modules by analyzing cloud management in three areas: interactions, end-to-end delay, and communication. In addition, optimizing the decoupling and orchestration scheduling of micro-service cloud management system components to achieve elastic management scaling. To the best of our knowledge, no work has investigated cloud management as a workload required for elastic resource provisioning. In comparison to a monolithic architecture, the proposed micro-service-based model achieves 45% to 65% enhancement in elastic scaling performance.
