The secret of successful SOA
Composite service oriented architecture (SOA) business services are stressing
traditional IT management strategies and tools to the breaking point. This is
what many CIOs are learning the hard way, according to Ovum Summit, the analyst
and consulting company. Successful SOA deployments demand state-of-the-art IT
Ovum recently conducted a survey of 333 North American IT decision-makers representing
a mix of enterprise and mid-market customers. The survey identified strong connections
between an organisations commitment to managing IT as a set of services
and the success of its SOA implementation.
Our survey strongly indicates that successful SOA deployments need to
be supported with management strategies that take an end-to-end, cross-tier
look at the dependencies and relationships across the full set of systems and
software used to enable end-to-end business services, commented Mary Johnston
Turner, Ovum Summit Vice-president and author of the survey.
Traditional IT management approaches assume tight connections between systems
and applications, while SOA environments are much more loosely coupled. Customers
who have not made major changes to their day-to-day IT operations management
environment cant keep up with the operational demands of SOA as it scales
up from pilot project uses to full-blown enterprise-wide implementations,
The study found that the customers who have implemented IT service management
best practices (such as ITIL), along with policy-based automated management
tools, are twice as likely as other firms to report that their SOA investments
are meeting all their IT and business goals.
Results show that the most satisfied SOA customers aim to improve business flexibility
and ITs responsiveness to changing business needs. The least satisfied
customers appear fixated on development cycle time and software re-use improvements,
but tend to overlook the increased levels of operational complexity that result
from the deployment of SOA.
