112 It is common now, that operating system deals with hardware. This includes layers Link and Internet that can be called also media layers. The Application and Transport layers are host layers, and lowers in this group is Transport layer. This layer can give considerable speed and implementing complexity. Thus Transport layer best fits our purpose of creating communication between microservices. There are two protocols on the transport layer – TCP and UDP. UDP is quicker, but it is stateless and doesn‘t track data sequence. It is not very good for communication purposes, so we chose TCP protocol. Most computer languages have embedded libraries to work on a TCP level. We can use it to construct communication system. TCP connection is based on server- client technology. To communicate multiple microservices we need some kind of broker. Let‘s name it EventBroker (Fig.1). Fig.1. EventBroker microservice
