Storage would seem to be the next logical vertical to be impacted by open source. With a trend toward federated storage clusters, there will be a need for a central control mechanism, not unlike that of SDN. A single point of control spanning heterogeneous architectures is ideally suited for open source efforts.
The point here is not that open source is a necessary, evolutionary step, but rather that open source becomes a key ingredient as conditions in a technology space favor the value that open source brings. Where there is commonality in platform or control, open source will thrive. Where specialization is critical, open source is less relevant. As companies look at their own open source participation, they should examine natural points of convergence. The conditions more than the projects are likely to determine the success of open source across the various technology areas of IT.
