The FaaS-Based Cloud Agnostic Architecture of Medical Services—Polish Case Study

In this paper, the authors, based on a case study of Polish healthcare IT system being deployed to cloud, show possibilities for limiting computing resources consumption rarely used services. The architecture today’s developed application systems is often architectural style microservices, where individual groups services are independently each other. This also with under discussion. Most often, nature workload group different, which creates some challenges but provides opportunities make optimizations in resources, thus lowering environmental footprint and at same time gaining measurable financial benefits. Unlike other scaling methods, such as those MDP reinforcement learning particular, focus load prediction, authors propose reactive approach any, even unpredictable, change may result (autoscaling) number instances processes so adapt current demand soon possible. authors’ main motivation undertaking observe growing interest implementing FaaS technology production many fields, relatively little adoption field. Thus, part research conducted here, solution infrequently enabling so-called scale-to-zero feature using model implemented by Fission tool. compatible cloud-agnostic turn helps avoid cloud vendor lock-in. Using example question, quantitative experimental results showing savings achieved presented, proving justification novel implementation field systems.
