<strong>Planning</strong> <strong>and</strong> <strong>Impleme</strong>nting SOA<br />
ADOPTION OF SOA BY ENTERPRISES<br />
CATALYST<br />
Service Oriented Architecture (SOA) has become one of the latest buzzwords propagated by the IT industry.<br />
Most enterprises have now heard of SOA – at least to some extent – but how are they responding to it? Adoption<br />
rates vary enormously across various studies <strong>and</strong> this Section examines the evidence so far on adoption rates.<br />
With the promise to deliver flexibility <strong>and</strong> agility to the enterprise by dramatically cutting development<br />
times <strong>and</strong> costs, SOA has become a ‘hot topic’ in enterprise IT departments. The adoption of SOA has<br />
already become reality for a number of enterprises with the following key trends emerging:<br />
SUMMARY<br />
SOA adoption rates vary significantly across enterprises.<br />
Staffing issues, security concerns, <strong>and</strong> a lack of awareness of SOA are inhibiting SOA<br />
adoption.<br />
Enterprises expect cost savings to come from SOA deployment, though these will be<br />
in the long term.<br />
ANALYSIS<br />
SOA adoption rates vary significantly across enterprises.<br />
News articles during 2006 have quoted wildly different rates of adoption for SOA, ranging from figures indicating<br />
some 80% of organisations are working on SOA projects to rather more realistic adoption rates of less than 30%.<br />
Any new paradigm is bound to take time to get a widespread underst<strong>and</strong>ing, <strong>and</strong> it will often depend on where<br />
an organisation is currently in its IT adoption as to what their level of interest is in SOA.<br />
A recent survey of 90 end users in the US <strong>and</strong> in Western Europe (UK, France <strong>and</strong> Germany) conducted by<br />
Datamonitor provides insight into enterprises’ reaction to SOA. Some 30% of the respondents said that they were<br />
beginning to embrace a SOA infrastructure. Within the survey group, size of organisation also appeared to be an<br />
important factor on adoption rates. For example, Figure 8.1.1 illustrates that adoption rates in larger<br />
organisations were significantly higher than in smaller ones.<br />
