Modelling microservices in email-marketing concepts, implementation and experiences

Our experience with email-based marketing campaigns (or short: “Microservices”) showed that they are an intersecting set of a) projects and processes and b) technology and creativity. Their properties of fixed due date, fixed scope and at the same time fixed duration render classical management methodologies unfeasible. The same applies to the supporting enterprise infrastructure architecture, where ad-hoc changes lead to a loss of stability and performance. The remedy was found in Model-Driven Engineering; a choreography for Microservices helped to indicate improvement opportunities for both the architecture and the information flow within, which in turn increased throughput.
