Microservices Management on Cloud/Edge Environments

The microservices architecture is a promising approach for application development, deployment, and evolution, both on cloud and emerging fog/edge platforms. Microservices' single functionality, small size, and independent development/deployment support faster and cheaper scaling of pressing functionalities on cloud systems. They support applications' evolution via service reuse and smooth service modification/inclusion. Individual or sets of inter-related services may also be dynamically deployed onto resource-restricted nodes closer to end devices and data sources, which are typical of fog/edge computational platforms. The resulting system is very complex and impossible to be adequately managed manually. This work presents an automatic solution for microservices' deployment/replication in the fog/edge, adapting the system according to the runtime evaluation of client accesses and resource usage. The evaluation validates the adaptability and performance gains.
