Hajo Normann details on how to design a BPM/SOA solution including: modeling human interaction, improving BPM models, orchestrating composed services, central task management, new approaches for business-IT alignment, solutions for non-deterministic processes, and choreography.
In this presentation, Google architect Gregor Hohpe introduces various concepts for to manage more complex interactions between services, including conversations, choreography, and orchestration. He provides a down-to-earth look at these concepts along with the associated Web services standards like WS-BPEL and WS-CDL, and identifies common patterns in service conversation.
Gregor Hohpe debunks many unrealistic claims about SOA and addresses the technical issues, such as the false sense of simplicity, differences to established programming models and the importance of documentation. He also criticizes what he calls "Doodleware", i.e. tools that aim to hide complexity behind a graphical process model notation, and suggests deriving models from running systems.
