CentOS 5.3 Has Keen Focus on Virtualization
CentOS, the popular community-supported clone of Red Hat Enterprise Linux, hit Version 5.3 in March, some three months after its parent distribution, RHEL 5.3 began shipping.
CentOS is based on Red Hat's freely available Enterprise Linux source packages. The CentOS project strips trademarked logos and other branding from the packages before building them into a free, Linux-based, operating system that boasts binary compatibility with its parent.
Version 5.3 of CentOS shares in RHEL's recent improvements around virtualization, application development, security and storage. Unlike, RHEL, CentOS may be had without any subscription fees, which makes CentOS a popular operating system option for many hosting providers and cloud computing vendors.
Applications designed and tested to work with RHEL should work just the same on CentOS, and security and bugfix patches from Red Hat flow downstream to CentOS, as well. However, the distribution lacks direct support from Red Hat, and CentOS systems can't be managed through the Red Hat Network service.
