Abstract	With the advent of Docker, deploying microservices in application containers has become increasingly popular. The recent incorporation of libnetwork in Docker provides out of the box support for connecting distributed containers via either a native or a third party overlay driver. However, overlay networks introduces an implicit overhead. Additionally, geographic dispersion of containers may have an adverse effect on performance. In this paper, we explore the performance of various Docker overlay solutions when deployed in a high latency environment. We evaluate the deployment feasibility of various overlay solutions in the GÉANT Testbeds Service. Subsequently we measure the performance of the native Docker overlay driver and third party solutions Flannel and Weave via means of a synthetic point-to-point benchmark and a streaming media application benchmark. In either benchmark no significant performance deterioration was identified regarding latency or jitter. UDP and TCP throughput measurements exhibit irregular behavior and require further investigation.
