We often get asked what open source software is and why companies prefer it over proprietary software. The short answer is: it is cheaper in both the short and the long run because it has no license costs. It also reduces risk because there is no lock-in with the vendor of the software. And it is usually safer and better because the source code is open and can be improved by anyone.
This can also be confirmed by comparing the latest global study on open source adoption conducted by the company OpenLogic and the non-profit organization Open Source Initiative.
