Restful web services vs. "big"' web services: making the right architectural decision
TL;DR: This paper objectify the WS-* vs. REST debate by giving a quantitative technical comparison based on architectural principles and decisions and shows that the two approaches differ in the number of architectural decisions that must be made and in theNumber of available alternatives.
Journal ArticleDOI
Microservices tenets
TL;DR: This analysis confirms that microservices indeed can be seen as a development- and deployment-level variant of SOA; such microservices implementations have the potential to overcome the deficiencies of earlier approaches to SOA realizations by employing modern software engineering paradigms and Web technologies.
Journal ArticleDOI
Managing architectural decision models with dependency relations, integrity constraints, and production rules
TL;DR: A formal definition of architectural decision models as directed acyclic graphs with several types of nodes and edges is proposed, which can be used to verify integrity constraints and to organize the decision making process.
Proceedings ArticleDOI
Service-oriented architecture and business process choreography in an order management scenario: rationale, concepts, lessons learned
TL;DR: This paper discusses the rationale behind the decision for SOA, process choreography, and Web services, and gives an overview of the BPEL-centric process choreographic architecture and features lessons learned and best practices identified during design, implementation, and rollout of the solution.
Book ChapterDOI
Service Cutter: A Systematic Approach to Service Decomposition
TL;DR: Results as well as early feedback from members of the target audience in industry and academia suggest that the coupling criteria catalog and tool-supported service decomposition approach have the potential to assist a service architect's design decisions in a viable and practical manner.
