Or how to connect the architecture dots to support a smart connected planet.
The notion of a connected planet is far from new. However, the number of
connections as illustrated in figure 1 is growing at an exponential rate, and
it is fast becoming a reality in which many organizations must operate.
However, I doubt many organizations are preparing for this in a systematic
way. More likely, experience suggests that dozens of connected ‘solutions'
will permeate the organization via myriad routes and just add to the
complexity of the business and IT landscape, becoming yet more spaghetti that
someone is left to untangle.
Architecture is key to dealing with this. However, architectural practices
must evolve to themselves become more connected, and not a set of isolated
disciplines as they are often practiced today. Hence, in this note as well as
considering ... (more)
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.
It might be easy to conclude that SOA was yesterday’s issue. In fact
according to some pundits SOA is dead and business transformation,
application and IT modernization, and... (more)
A Reference Architecture (RA) “should” provide a blueprint or template
architecture that can be reused by others wishing to adopt a similar
solution. A Reference Model (RM) should explain the concepts and
relationships that underlie the RA. At Everware-CBDI we then use the term
Reference Framework (RF) as a container for both. Reference architectures,
models and frameworks help to make sense of Cloud Computing.
Unfortunately, such formality is absent from the various reference
architectures, models and frameworks that have been published for Cloud
Computing; t... (more)
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 I
consider several migration alternatives, expressed as a set of patterns. The
patterns should serve as a useful way to communicate intent. When someone
suggests that a current application could be migrated to the cloud, then
these patterns should be a simple way to ask "what exactly do you mean by
that, and what do you hope to achieve by doing so?"

The terms virtualization, utility computing and Cloud computing are often
used interchangeably which can be very confusing. A new report I have just
authored aims to provide clarification - to identify the similarities and
differences in those characteristics, and provide a framework in which
organizations can decide which capabilities they require in specific
situations – as it is unlikely that one model alone will suit all their
A visitor from outer space would be forgiven for thinking that
virtualization, utility computing and Cloud computing are different
