The problem with IT today ….The problem with IT today ….

I can’t reconcile my IT costs with the business value I’m deliveringI have systems with spare capacity and systems that need more resources, but I can’t shift the work from one to anotherAll the information I need is here somewhere, but it’s hidden, fragmented & inconsistentWhat the business sees as a minor change always turns into a significant development projectComplex requirements take so long to implement that IT gets further out of step with the businessI can’t justify the resources for running occasional compute-intensive modelling & analysis workI spend so much effort tackling IT issues I lose focus on the businessI’m meeting all my IT SLAs, but users still complain of poor performance

The more IT resources I accumulate,

the less I can do with them

Virtual Platform: Exploiting available physical resources to best meet the needs of a variable workload

On-Demand: Providing IT as a consumable commodity, at commodity prices

SOA: Delivering IT functionality as reusable, interoperable, location independent services

Autonomic: self-managing, self-healing, self-tuning, self-securing

Dynamic IT: giving users all the resources they need at the time they are needed, at a cost that is related to the business value delivered

Web services & Service Oriented ArchitectureWeb services & Service Oriented Architecture

Web services Defines a means of interoperability between

heterogeneous systems that is based on standards and requires no knowledge by one system of the specific technologies & methods used to build any other

Technology integration focused – bottom up approach to design

Service Oriented Architecture An architecture that exploits (but is not restricted to) the

interoperability provided by Web services to deliver business agility through rapidly constructing and adapting business processes and composite applications

Business focused – top-down focus on requirements


IDC’s taxonomy definition of SOA Service Oriented Architecture (SOA) is a technology

architecture based on disaggregation. It promotes the utilization of autonomous application and system "services" abstracted from one another, independent of implementation. Ideally, an SOA should be modular, with separate layers of functional code, data, workflow, and presentation interfaces.

Each service should be self-describing with a published interface, accessible to other elements of the system, most commonly over a network. In an SOA, services are designed to be dynamically invoked.

Danger of definition fixation, but:Danger of definition fixation, but:


More importantly – why?More importantly – why?

What is SOA good for? Accomodating rapid changes to the business Permitting more complex applications to be created Building IT processes that directly map to business

processes Extending applications and processes beyond

organisational boundaries Re-using existing IT investments Prolonging the useful life of previous expenditure Accomodating future technology innovations

SOA expectations now include: Technology transparent – invoked by messages (not APIs) Location transparent, dynamic use Description & usage information (interface contract) stored

in a repository of service definitions
