Why their Detections are Important?  to assess the design and quality of service of SBSs  to ease the maintenance and evolution of SBSs An in-depth understanding and relationships among different service antipatterns is the first and crucial step to perform their detection A Study on the Taxonomy of Service Antipatterns 4
  7. 7. Benefits of Taxonomy (1) assists in the specification and detection of service antipatterns (2) reveals the relationships among various groups of service antipatterns (3) groups together antipatterns that are fundamentally related (4) provides an overview of various system-level design problems, etc. A Study on the Taxonomy of Service Antipatterns 5

  12. 12. Related Work  previous contributions addressed OO code/design smells  service smells/antipatterns (in the service domain) holds the same notion to OO smells/antipatterns, but at the service-level - service is coarser-grained and at higher-level of abstraction than OO classes  no taxonomy is proposed for service antipatterns in the literature A Study on the Taxonomy of Service Antipatterns 7

  17. 17. Classification of Service Antipatterns  Classification of service antipatterns in two categories: - Existential - Intra-service (e.g., Multi Service) - Inter-service (e.g., Service Chain) - Analytical - Static service antipatterns (e.g., Low Cohesive Operation) - Dynamic service antipatterns (e.g., Bottleneck Service) - Compound service antipatterns (e.g., Chatty Web Service)  Service smells - indicators of the presence of service antipatterns in SBSs - lower-level design problems than antipatterns - can be classified as measurable, structural, or lexical A Study on the Taxonomy of Service Antipatterns 10
