Query: Parsimonious Edge Computing to Reduce Microservice Resource Usage   Cloud Computing (CC) is the most prevalent paradigm under which services are
provided over the Internet. The most relevant feature for its success is its
capability to promptly scale service based on user demand. When scaling, the
main objective is to maximize as much as possible service performance.
Moreover, resources in the Cloud are usually so abundant, that they can be
assumed infinite from the service point of view: an application provider can
have as many servers it wills, as long it pays for it. This model has some
limitations. First, energy efficiency is not among the first criteria for
scaling decisions, which has raised concerns about the environmental effects of
today's wild computations in the Cloud. Moreover, it is not viable for Edge
Computing (EC), a paradigm in which computational resources are distributed up
to the very edge of the network, i.e., co-located with base stations or access
points. In edge nodes, resources are limited, which imposes different
parsimonious scaling strategies to be adopted. In this work, we design a
scaling strategy aimed to instantiate, parsimoniously, a number of
microservices sufficient to guarantee a certain Quality of Service (QoS)
target. We implement such a strategy in a Kubernetes/Docker environment. The
strategy is based on a simple Proportional-Integrative-Derivative (PID)
controller. In this paper we describe the system design and a preliminary
performance evaluation.
