Planning and Implementing SOA: Ensuring the Successful Deployment of a Services-based Approach
“Service Oriented Architecture (SOA) is destined to be one of the defining IT paradigms of the next decade. It promises the delivery of IT services in a loosely-coupled way that is more flexible and better aligned with business needs than previous architectures. SOA is an architectural style, not a technology, which allows the creation and maintenance of an IT architecture that supports business services and business processes, and also rapidly adapts to the changes within them.

The adoption of SOA has significant potential to improve the value organisations derive from their IT investments, in terms of increased flexibility, improved use of assets, alignment with business objectives, and reduced integration costs. However, there is still a considerable degree of hype and misunderstanding around the topic, with consequent confusion as to the exact definition of a SOA, and more importantly, how to begin to realise these benefits.

Key Findings
Over the next five years, SOA will transform the way IT and the organisation interact, enabling  improved IT agility and the rebuilding of trust with the enterprise.
*Whilst still mainly in the proof-of-concept or pilot phase at many organisations, the adoption of SOA is continuing to gain momentum, despite challenges such as security, performance, and a lack of
available skills.
*When deploying SOA it pays to start small, but think big, and to choose a business problem that SOA can help resolve as a starting point.
*There is a great deal of synergy between Business Process Management (BPM) and SOA, with BPM providing a common point of reference for both the organisation and IT.
*The use of standards is crucial to enable interoperability, and to prevent vendor lock-in.
*A policy-driven approach is required to control and secure the services-based environment.
*Service quality is a key consideration if the goal of reuse is to be attained, encompassing a registry, governance, control, and management capabilities.
*It is important to address the implications that a move to a layered architecture can bring, and the wider operational aspects of supporting SOA.
