A Service Performance based Dynamic Provisioning Approach in Containerized Cloud Environments

Along with the evolution of cloud technology and big data technology, cloud service is becoming an emerging trend for big data processing. Cloud services are facing the challenges of dynamic provisioning and adaptation to the unpredictability of business requirements. The emergence of container technologies provides new technical opportunities for the optimization of service performance and the dynamic provisioning in cloud environments. In this paper, a service performance based dynamic provisioning approach in containerized cloud environments is proposed. The approach continuously monitors and collects the system metrics and based on the metrics customized scheduling strategies of the cloud environment are dynamically designed and adjusted. The feasibility of the approach is verified by experiments, and the experimental results show that the proposed approach can successfully completed the dynamic provisioning of the cloud environment, and it can improve the availability and reliability of cloud services. It is a new attempt of the cloud support environment to meet the business requirements.
