The Evolution of Systems Integration
What I mean when I say that Systems Integration and the notion of Systems are evolving is that new design concepts and technologies are having a radical and disruptive influence on current integration practices, processes and design approaches. What was a ‘system’ under distributed computing environments is now undergoing a transformation – taking on aspects of both the distributed model used today and centralized models from yester-year. This is largely coming about due to the advent of Services Oriented Architecture (SOA) technology and design principles. It is important to note here that SOA, like Semantics, is a practice area based upon design philosophies and technical standards – the tools being developed in relation to those philosophies standards or applied to it are not the drivers for these trends. Folks who focus on the software tools only and not the underlying principles tend to run into many difficulties in implementing these types of new capability.
Our previous or current experience with System of Systems architectures is what led to the need for System Integration and Integrators largely as an afterthought or mitigating action in response to the need for rapid deployment of multiple, new distributed technologies. Most enterprises have spent the last twenty years playing catch-up in this environment and few are truly architected in any comprehensive sense of the term. System Integration is often a tactical activity – ensuring data passes between systems silos, connecting various applications point-to-point or through limited middleware capabilities, deploying portals and unified sign-on and security management and so forth. Piece by piece, an enterprise becomes more unified under this type of scenario, but at a cost – that cost is increased complexity and expense for maintaining non-standard integration.
The future is upon us; that future is just now promising something new – the ability to coordinate architectures across tiers, across federated domains and across all related lifecycles. The new enterprise can be viewed as a single organic system, consisting of dozens or hundreds of services that operate as a single unified yet dynamic entity that is often federated across geographic and logical domain or boundaries and orchestrated at runtime. This is SOA but it is more than SOA, because SOA doesn’t yet have the necessary philosophical framework for exploitation of Semantics to help achieve this enterprise unification. That’s where Semantic Integration comes into the picture.
