This paper looks at organization of micro-controllers in a Service Oriented Architecture in road vehicles. Research is being done on why SOA was originally considered by automotive manufacturers and compares the situation with the one of nowadays. Overview of a common implementation setup is provided as an example to showcase the resulting complexity of the solution. This is followed by a discussion on alternative paths that may be taken to reduce the overall cost of the solution with comparison of key differentiating points between SOA and the alternative solution. Keywords: SOA; Micro Services; design patterns; cost efficiency; Separation of Concerns; Forced Encapsulation. 1 Introduction Vehicle manufacturing industry is over 100 years old. It has experienced numerous changes in approaches to manufacturing, design and market positioning. What’s even more important, over that time the industry had the opportunity to degrade some design and manufacturing cues that were deemed ineffective, only to reinvent them decades later in a different context. One such change took place at the end of the 1980s, when computerization of vehicles became economically viable. Not only it altered the production processes, but it also required the whole product to be regarded in a different manner. No longer was it a set of mechanical elements with given projected reliability, but rather a complete system that can be designed in a way we understand the systems design and development today.
