Russ Miles and Toby Hobson outline many factors to be considered when adopting a cloud solution – what type of cloud, which vendor, what technology, how is it related to the business value, SLA, should it be considered early, geo-location constraints, etc. –, creating a wider view of the cloud from the development and business perspective.
Next Generation of Business-Driven SOA: The Convergence of Performance-Driven Business and Service-Orientation
John DesJardins believes that a new generation of SOA is about to emerge, one based on business performance achieved through continuous process improvements driven by business metrics and IT collaboration. Organizations will measure their businesses alignment with IT in order to asses the impact of services, the impact of changes or new initiatives, up-time, response time, etc.
Anne Thomas Manes, who pronounced SOA dead a year ago, talks about the reincarnation of SOA. She believes the old SOA had to die because it was too much focused on technology and products, while the new one, absolutely necessary for the new cloud computing era, will be focused on architecture, principles and practices.
Paul Downey discusses the risks of premature standardisation, unnatural constraints, partial implementations and open extensions, how to avoid cloud computing lock-in, formal activities versus lightweight open processes as exemplified by open source, Microformats, OpenID, OAuth and other Web conventions being ratified through open, lightweight, continuous agreement.
Ian Robinson on what organizational and social issues should be addressed when starting a new SOA project by identifying business capabilities using user stories, describing services and their contracts, and how to set up teams for delivery.
RESTful architectures are the subject of this presentation, specifically the way they are particularly attractive in solving many financial services integration problems. Kirk will present the advantages of a RESTful architecture to develop integrated systems in the financial services arena, in particular leveraging infrastructure, skills, and systems already in place at these firms.
This presentation, from QCon SF 08, analyzes real world projects where using explicit state transition models was made and the many interesting modeling/architectural possibilities that arose from the decision. Along the way, the IMIS system and its performance is linked to explicit state transition modeling.
In this presentation, recorded at QCon San Francisco, ThoughtWorks director of professional services and all-around Web and Web services expert Jim Webber explains the core concepts of message-oriented web services, expresses his thorough dislike of WSDL, explains different approaches to Web architecture, and shows an example of a RESTful workflow.
In this presentation filmed during Agile 2007, Stacia Broderick introduces Agile to traditionally trained project managers by making a comparison between Project Management Institute's (PMI) best practices and their equivalent Agile techniques.
Jay Fields presents his concept of Business Natural Languages (BNL). BNLs are a type of Domain Specific Language, designed to be readable by any subject matter expert, which allows to create maintainable specifications and documentation. The example language is shown using Ruby.
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.
