| contents | Many online services running in datacenters are implemented using a microservice software architecture characterized by strict latency requirements. Consequently, this popular software paradigm is increasingly used for the performance evaluation of server systems. Due to the scale and complexity of datacenters, the evaluation of server optimization techniques is usually done on a smaller scale using a client-server model. Although the experimental details of the server side are excessively described in most publications, the client side is often ignored. This paper identifies the hardware configuration of the client side as an important source of performance variation that can affect the accuracy and the correctness of the conclusions of a study that analyzes the performance of microservices. This is partially attributed to the strict latency requirements of microservices and the small scale of the experimental environment. In this work we present, using a widely used online-service, several examples where the accuracy and the trends of the conclusions differ based on the configuration of the client-side. At the same time we show that the experimental evaluation time can be significantly affected by the hardware configuration of the client. All these provoke the discussion of the right way to configure the experimental environment for assessing the performance of microservices. |
