About the Authors
Olaf Zimmermann is a long-time service orienteer with a PhD in architectural decision modeling. As consultant and professor of software architecture at the Institute for Software at Eastern Switzerland University of Applied Sciences, he focuses on agile architecting, application integration, cloud-nativity, domain-driven design, and service-oriented systems. In his previous life as a software architect at ABB and IBM, he had e-business and enterprise application development clients around the world and worked on systems and network management middleware earlier. Olaf is a Distinguished (Chief/Lead) IT Architect at The Open Group and co-edits the Insights column in IEEE Software. He is an author of Perspectives on Web Services and the first IBM Redbook on Eclipse. He blogs at ozimmer.ch and medium.com/olzzio.
Mirko Stocker is a programmer by heart who could not decide whether he liked frontend or backend development more, so he stayed in the middle and discovered that APIs hold many interesting challenges as well. He cofounded two startups in the legal tech sector, one of which he still chairs as managing director. This path has led him to become a professor of software engineering at the Eastern Switzerland University of Applied Sciences, where he researches and teaches in the areas of programming languages, software architecture, and Web engineering.
Daniel Lübke is an independent coding and consulting software architect with a focus on business process automation and digitization projects. His interests are software architecture, business process design, and system integration, which inherently require APIs to develop solutions. He received his PhD at the Leibniz Universität Hannover, Germany, in 2007 and has worked in many industry projects in different domains since then. Daniel is author and editor of several books, articles, and research papers; gives training; and regularly presents at conferences on topics of APIs and software architecture.
Uwe Zdun is a full professor of software architecture at the Faculty of Computer Science, University of Vienna. His work focuses on software design and architecture, empirical software engineering, distributed systems engineering (microservices, service-based, cloud, APIs, and blockchain-based systems), DevOps and continuous delivery, software patterns, software modeling, and model-driven development. Uwe has worked on many research and industry projects in these fields, and in addition to his scientific writing is co-author of the professional books Remoting Patterns—Foundations of Enterprise, Internet, and Realtime Distributed Object Middleware, Process-Driven SOA—Proven Patterns for Business-IT Alignment, and Software-Architektur.
Cesare Pautasso is a full professor at the Software Institute of the USI Faculty of Informatics, in Lugano, Switzerland, where he leads the Architecture, Design, and Web Information Systems Engineering research group. He chaired the 25th European Conference on Pattern Languages of Programs (EuroPLoP 2022). He was lucky to meet Olaf during a brief stint at the IBM Zurich Research Lab back in 2007, after receiving his PhD from ETH Zurich in 2004. He has co-authored SOA with REST (Prentice Hall, 2013) and, self-published the Beautiful APIs series, RESTful Dictionary, and Just Send an Email: Anti-patterns for Email-centric Organizations on LeanPub.
