With SOA and SaaS, Solution architectures have undergone two significant paradigm shifts in the past few years. One is the notion of breaking down a solution into coarse grained services pushed by SOA, and the other is to deliver software as a managed service, pushed by SaaS. With SaaS gaining mainstream recognition, amplified by the advent of virtualization platforms and web based computing options, the enterprise infrastructure is rapidly morphing into a large computing blurb- a 'computing cloud'.
The cloud spans dedicated servers, virtualized platforms, web based hosting, solutions in SaaS model, solutions built on PaaS, and much of these. All ready for user interactions in a Web2.0 model, and integration using the SOA backbone. This brings forth new possibilities for solution architectures, infrastructure, tools, and deployment considerations for business applications/products. SaaS/PaaS And SOA fits in rather snugly as a primary integration fabric. Largely driven by the location transparency, SOA ties in all the applications both within the enterprise network and beyond.
In this session we will discuss some of these trends in the virtualization space in the context of SOA. The outline: State of SOA, Enter SaaS, PaaS adding a new dimension, Virtualization- abstracting the hardware and operating layer, Where do they all meet?, The resulting computing cloud, The user interaction layer - Web2.0, The integration fabric- SOA, The backends- SaaS & PaaS, The synergies, Emerging enterprise architecture models, What to expect in 2009.
