Five open source tools for building and managing clouds
This article is part of the December 2010, Vol. 29 issue of Virtual Data Center
Open source technology is going to seriously impact the cloud computing world, and there are two main reasons why: Open source software is essentially free, and it is not generally encumbered by the software license models of proprietary software. Many proprietary software vendors, such as Microsoft and Oracle, are trying to maintain old and expensive license models, even though they impede the flexibility gained by virtualization and cloud computing. Proprietary tools for building and managing clouds are no further along than their open source counterparts, and the open source tools are free. Bill Claybrook A number of open source tools have already had a huge impact on cloud computing: Linux and Xen, for example. But there are other important open source offerings that can benefit cloud users. These include KVM, Deltacloud, Eucalyptus, Cloud.com's CloudStack Community Edition and OpenNebula. KVM KVM (Kernel-based Virtual Machine) is an open source hypervisor for Linux running on x86 hardware. It contains virtualization ...
