The open source approach has been gradually making its way into the cloud services marketplace. Eucalyptus System has developed open source cloud infrastructure software with interfaces that are compatible with Amazon's EC2 service. In business since early 2008, the venture based start up began its work as part of a National Science Foundation research project at University of California, Santa Barbara. Ubuntu is one of the many variants of the Linux operating system. Recently, the software has been tweaked so it can operate in the cloud.
GroundWork has been at the forefront of developing open source management software, so support for Eucalyptus and UEC fits with the company's business model. While small and medium businesses have been moving to cloud services, acceptance of open source services is in a nascent stage of development. Ground Work is trying to position itself to take advantage of a potential uptick in acceptance as the market matures.
