Technology and Patience
I know I talk a lot about the background here, but, one thing I
have learned from my mistakes is not to rush into technology. In
order to be effective in our execution we must correctly
identify the Business processes and the Business requirements.
Only then can we make a decision on what technology will work
best. Then, we draw a set of Service specifications. We measure
the specifications against the infrastructural constraints of
the organization in concern. A simple case may be that if most
of the IT application in a specific organization is already
written using Visual Basic, then we need to pause before we
propose a Java based solution. Remember, any technology is
capable of producing a Business solution and switching
technology means extra costs, which may need to be justified. So
please be patient until next part of this article, where we take
a step towards the technology.
Conclusion
In the first part of this series, we have layed out a case for
the Service Oriented Architecture, defined what Service actually
means and discussed few guidelines about identifying Services.
We have also warned about the danger in rushing to
technology too early in the process of SOA implementation. In
the next part of this article, we will talk about the Service
specification and take a step towards available lava based
technologies to implement Service Oriented Architecture.
Next month, we will talk about Service Specification and
available technology and in the final part, we will discuss the
most popular technology for SOA—Web Services.
