CentOS
which stands for Community Enterprise Operating System, is the result of a group of open source contributors and users working together to develop Linux solutions that are freely available to users who do not require a great deal of commercial support to achieve their goal.
CentOS dedicated servers were designed based on Red Hat’s product, Red Hat Enterprise Linux. Although the Red Hat Linux server is made entirely of free and open source software, it is only distributed to the public in binary form (including CD-ROM and DVD-ROM) at a fee paid by subscribers. However, Red Hat does release its source code for its product under the terms of the GNU General Public License.
Consider Community ENTerprise Operating System (CentOS) which is not
only free, but also o ers many benefits over other operating systems. CentOS
Linux distribution is an enterprise-grade, freely available, open source
operating system based on the open source code of Red Hat Enterprise Linux,
developed and maintained by CentOS Project. The project is about more than
just a Linux distribution because project members provide support and
training materials.
You could be a proud member of the community around the world who use
CentOS because they need a robust and reliable platform to deploy
applications and services. The project has commercial support options
available from several companies, but if you have your in-house expertise or
know people who can help, you could opt out of commercial support.
Ubuntu
- Ubuntu is a Linux-based Operating System
- It is Most Popular Linux Distribution.
- It is open sourced
- Cost free
- Non-proprietary
- Strong focus on
a.Usability
b.Easy to installation
c.One user (initially— you can add more users later)
Ubuntu, since its release in 2004, has risen to the vanguard of desktop Linux
and as a popular choice for servers. Ubuntu evolved from Debian, one of the
most stable and customisable distributions of Linux. Many talented software
developers like Ubuntu because it enables them to concentrate on specific
interests within the operating system. Ubuntu is a fast-changing distribution
with an updated release twice a year. If you are a business, you could realise
the benefits of running a stable and powerful operating system, which is not
only easy to maintain, but also easy to secure. The Unity interface for Ubuntu,
since its release in 2011, has become elegant, powerful, and more useful.
Ubuntu leverages on the quality of Debian and creates an operating system
for ordinary people; however, even expert developers love Ubuntu because it
allows them to concentrate on specific interests instead of details of the
operating system.
Debian
∘ Uses the Linux kernel and many GNU tools
∘ Started 1993 by Ian Murdock (Deb+Ian)
∘ Purely volunteer and community based
∘ APT for powerful software package management
∘ More precompiled packages than other distros
∘ More supported hardware architectures
∘ Base for: Ubuntu, Xandros, Knoppix
Debian is one of the most stable and customisable distributions of Linux and is
well-respected for quality and technology. The operating system is however
meant for geeks as the operating system has a flexible GNU/Linux-based
distribution from its packaging. The learning curve is quite steep for most web
developers, but Debian is a proven platform for web applications. Familiarity
with GNU/Linux is crucial, and experience with packaging systems and
managing performance or security are useful. The Debian Project aims to
produce a universal operating system, to run on a broad set of hardware for
wide-ranging purposes and di erent kernels including Linux, Hurd, or
FreeBSD. Choosing the right flavour of Debian could be simplified by using
recommendations for architecture and installation method. Success of Debian
could be attributed to the stability of software packages, robustness of
administrative tools, and reliability. Debian supports eleven di erent
processor architectures for unified administration across various platforms.
Since Debian uses the Linux kernel, anything possible with Linux is so possible
with Debian GNU.
