As the digital universe races full-steam ahead into the cloud, cloud-related technologies represent a fertile niche in which both aspiring and practicing IT professionals would do well to invest. Not much appears hotter at present than OpenStack. This free, open source platform for cloud computing is widely and often used for infrastructure-as-a-service (IaaS) deployments. OpenStack consists of over half a dozen interrelated elements to control resource pools for networking, storage and processing in a data center. OpenStack may be managed in a variety of ways, including through a web-based dashboard, command-line tools or even a RESTful API.
