On Friday 28 October 2011, the two-day Tech4Africa conference came to an end. The conference, which focuses on mobile, web and emerging technologies and with the goal of bringing a global perspective to the African context and finding African solutions for African problems, revealed that cloud computing could just be the best solution for emerging businesses on the continent. Ummeli (the Nguni word for mediator), a mobile career opportunity platform that helps jobseekers share job and unemployment opportunities was launched last week by Gustav Praekelt of the Praekelt Foundation. Also launching last week, was the 3G service in Central Africa by Airtel and the government of the Republic of Congo. The launch of the 3G platform promises changes to how subscribers in the region experience the web on internet-enabled devices and is reported to be the first 3G license issued in Central Africa.
