Open Source, the Fuel for Cloud Disruption
— Open source has proven to be a good option for building, managing, and delivering scalable infrastructure-as-a-service (IaaS) clouds and platform-as-a-service (PaaS) clouds. Typically, most open source cloud platforms support multiple virtualization technologies, giving enterprises a range of choices from multiple vendors of closed as well as open source technologies. Some examples are Eucalyptus, OpenStack, Cloud Foundry, OpenNebula, Red Hat OpenShift, Xen Cloud Platform Project (XCP), and the newest kid on the block, Citrix Cloudstack 3. While some apprehension still exists around open source use, there is a shift in attitude as enterprises look to capitalize on efficiency and technologies like virtualization and cloud computing as these become highly essential components in IT architecture.
OpenStack is a massively scalable cloud operating system that helps in the delivery and management of infrastructure. OpenStack is initiated by Rackspace and NASA, and is supported by almost 180 organizations, including Intel, Dell, Canonical, AMD, Cisco, HP, SUSE Linux, Red Hat, and IBM. It is a collaborative effort by thousands of developers and technologists globally aimed at helping SMBs, service providers, data centers, corporations and researchers roll out and leverage industry-grade public and private clouds.
