Software-as-a-Service is becoming the prevalent way of software delivery. The popularisation of microservices architecture and containers has facilitated the efficient development of complex SaaS applications. Yet, for average SaaS vendors, there are a lot of challenges in managing microservices at a large scale while meeting the Quality-of-Service constraints. In this paper, we present SmartVM, a business Service-Level-Agreement (SLA) aware, microservice-centric deployment framework, designed to streamline the process of building and deploying dynamically-scalable microservices that can handle traffic spikes in a cost-efficient manner. We also compare our approach with traditional monolithic and the state-of-the-art microservice deployment approaches. The evaluation results show our approach advances in deployment cost, resource utilisation, and SLA compliance.
