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.
Alfresco has just released version 5.0 GA of the Activiti engine, an Apache2 licensed BPMN 2.0 implementation. InfoQ talked with project lead Tom Baeyens on the new release. Tom is also the creator and former project lead for the jBPM project.
A panel of hard core developers, including Ted Neward and Jeffrey Palermo, assembled at TechEd 2009 has discussed the current economic difficult times and expressed their opinion on what a developer needs to do to remain employed.
Vertebra, announced at RailsConf 2008, has finally been released. Vertebra is a platform to develop and manage cloud applications. We talked to Engine Yard founder and architect Jayson Vantuyl about what Vertebra and its use of XMPP bring to the table.
Jack Greenfield gave a presentation at the last PDC on the architecture of Multi-Enterprise Business Applications. He sees MEBAs as being applicable to a large number of industries and processes. In the presentation he introduced a MEBA model-driven framework that his team has set out to build.
With SOA maturing, it becomes more apparent that many people are getting lost in the “alphabet soup” of the terms that are interpreted and misinterpreted differently by many people. This makes it even harder for people, discussing complex SOA issues, to understand each other.
WS-CDL has struggled from birth to find mainstream acceptance. Now one of the main authors, Steve Ross-Talbot, has compared one of the principles behind WS-CDL, that of precision in defining services, to that of the micrometer during the early industrial revolution. Can WS-CDL have the same impact as the micrometer and really facilitate service reuse?
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.
Ralph Johnson and Joe Armstrong discuss their ideas about parallel programming - whether shared memory is harmful, the place of message passing, fault tolerance, the importance of protocols and more.
In this interview, recorded at QCon London, Google architect Gregor Hohpe talks to Stefan Tilkov about his new work on conversation patterns. Building upon his earlier work on enterprise integration patterns, Gregor sees conversation patterns as playing a critical role in real-world interactions, with analogies in the natural world.
