Analysts are advising developers to ensure that they broaden their skill sets to include open source.
A recent study by the National Computing Centre on behalf of IT services provider Atos Origin found more than two-thirds of senior IT professionals questioned expected to develop an open source strategy in the next five years.
Just over 60% of companies said they believed open source will increase its presence in their business or will be a fundamental component in core IT systems, while 73% said they expected open source to become part of their organisation's IT strategy in the next five years.
David Mitchell, practice leader in software with analysts Ovum said: “The days of just being a developer in Cobol or C++ are over and I would recommend developers look at the breadth of tools and experience they have.
"While Microsoft and other proprietary development environment are clearly very strong and will continue to be, looking at having a broad skills portfolio that includes open source is the best way to do things.”
“The most important development tool that we see emerging in open source is Eclipse, and any developer should consider what it means to them,” he added.
