In 2010, Bouke Koelstra joined Capgemini. But, he has gained his first experience with open source in 2004 when he was closely involved in the project called A7. Later, Bouke also contributed to OSOSS; a government program that aimed to provide information about open source software. Then, he ran into Zarafa frequently, which currently still is the fastest growing groupware platform within Dutch government organizations.
At this moment, Bouke works at Gapgemini Infrastructure. He is now busy with setting up an Open Source Cloud Workplace. This year, its clients will be able to purchase a complete environment, consisting of open source software and open standards, in a 'pay per use' model. Zarafa as a Service will be one of the main components.
