We had an amazing 3 days at WSO2Con 2013. In addition to the inspirational keynote presentations, technical sessions and tutorials which explored best practices in API management, SOA, open source, cloud computing, mobile, data and analytics, application development, enterprise integration and governance, a highlight of the conference was a demonstration of the WSO2Con mobile application built using WSO2 Carbon enterprise middleware and running on a cluster of 24 Raspberry Pi computers.
