In this IEEE article, authors Stephen Yau and Ho An talk about application development using service-oriented architecture and cloud computing technologies. They also discuss application development challenges like security in a multi-tenant environment, quality-of-service monitoring, and mobile computing.
OMG CEO Richard Soley in a recent interview shares his observations on hype cycle effects on adoption patterns and how it may affect cloud computing like it did SOA. He extolls some virtues of cloud computing for startups and also explains why it may still not be as big a deal for larger businesses, despite the hype.
Service Oriented Architectures (SOA) are associated with business applications and integrations. A recent IEEE publication describes the architecture and processes to achieve relatively seamless integration between the burgeoning 'Internet of Things' with the 'Internet of Services'.
A new whitepaper from the SOA consortium defines business driven SOA and the role of business architecture in its implementation. It also repositions business architecture from a collection of artifacts required for implementing IT solutions to a comprehensive approach to the entire business design.
SOA and Cloud computing experts discuss relationships between SOA and Cloud computing, principles and technologies they can/should share, the applications that can best leverage combining SOA and Cloud computing and the things that are the most important for Cloud computing success.
In this IEEE article, Richard Welke, Rudy Hirschheim and Andrew Schwarz discuss a SOA maturity model that can be used to achieve organizational objectives, by accounting for the different motivations for SOA adoption by stakeholders like IT administrators, business managers, and enterprise leaders.
Service-Oriented Architecture Decision Modeling (SOAD) framework helps to capture the recurring architectural decisions and use them to guide design in related projects. In this IEEE article, author Olaf Zimmermann discusses this decision-centric approach to guiding the design work. He also talks about the two model types in SOAD metamodel, the guidance models and the decision models.
Eric Jan Malotaux presents a way of implementing SOA in small iterative steps, each step delivering value to stakeholders, higher than the costs involved, using feedback from previous steps to adjust the requirements and design accordingly.
Brian Nicks presents a study case of a healthcare company which inherited many disparate technologies from Java on WebLogic to .Net to RPG on iSeries to CICS on zSeries to COBOL on OpenVMS, deciding that the integration solution was to implement a SOA initiative. The presentation contains the challenges, the successes and the lessons learned throughout the process.
