Service Specification Survey Results

12 Nov 2013

Services are progressively becoming the de facto architecture for the enterprise. Whether a service is implemented as a REST API or SOAP Web Service, a specification of some sort is essential for the delivery and operational life cycle management. Casual observation tells us that service specification approaches in common use are highly variable. In our survey, conducted in October 2013 we asked architects, designers and project managers to tell us how they deliver and use service specifications. The results substantiate preconceptions to some extent, but also highlight some very interesting issues.

Research Notes by Topic

Application Migration Patterns for the Service Oriented Cloud

As well as deploying new applications to the cloud, many organizations will also be considering the opportunities to migrate current applications to the cloud in search of reduced costs or SLA improvements.  In this research note we consider several migration alternatives, expressed as a set of patterns.

The patterns can also be seen as a sequence of activities, through which the current application is gradually modernized.

In the Service Oriented Cloud, All Roads Lead to SOA

Cloud Computing is intrinsically service-based. But this is not just in the highly generalized sense of the term ‘service’, but also in the more specific Service Oriented Architecture (SOA) use of the term, where capabilities are provided via published service interfaces. In this research note we consider why SOA should not be forgotten just because more fashionable terms have risen to the top of the toybox.

Integrating Strategic Planning for Cloud and SOA

Moving to Cloud Computing at any level, private, public or hybrid, represents a major challenge and opportunity for enterprises. But for an enterprise getting beyond the experimentation, niche and commodity applications to actually deliver the expected cost benefits with minimum risk is always harder than anticipated. Full blown Cloud adoption implies mature and sophisticated SOA implementation and impacts many business processes and requires coordination of multiple, disparate disciplines.  Experience tells us such an adoption process requires integrated business driven strategic planning.

Cloud Computing Reference Architectures, Models and Frameworks

There are a plethora of different reference architectures, models and frameworks for Cloud Computing. Which one should an organization adopt? Of course there’s no straightforward answer to that question and in this research note we provide guidance on how to organize some of the best ideas that are emerging in a practical structure that should stand the test of time.
