Canonizing a Language for Architecture: An SOA Service Category Matrix Published at Service Technology Magazine Issue LXXII

Services have to meet different architecture and governance requirements and their relevance is determined by how the services are reused. The arrangement and structure significantly affect the analysis and design of the services, which in turn determine the level of granularity. Categorizing services makes it easy to arrange them according to service usage in the procedural landscape, which helps prevent unwanted entanglements.

SOA architectures that have not undergone categorization quickly become “adapter” SOAs that lack a clear division of responsibilities. The orchestration of business processes in these architectures is interspersed with technical service calls that can lead to unaccountable call sequences.

To tackle these challenges, a vocabulary that SOA professionals can use to describe different types of services has been developed. We explore the various possibilities for categorizing SOA services in this article, before introducing the range of service categories that we have successfully implemented in projects. The SOA service categorization matrix in Figure 1 contextualizes the concepts that are presented.
