There is no best operating system which one can , say but it all depends on the enterprise need to determine the one to be selected.Today, Linux is more than a free OS to mess around with -- it runs core business applications. When comparing the most popular Linux distributions, corporate Linux users care about support throughout the stack, not just an attractive feature set.
Any company can run a free and open source Linux distribution in an enterprise environment, but most have serious restrictions. In particular, the maintenance lifetime of most free distributions is limited. The popular OpenSUSE distribution, for instance, has an-month lifecycle, meaning that a security issue that occurs months after the initial release date will go un-patched. And it takes about months to get a Linux distribution approved for use in the corporate world. Distributions with such a short life cycle aren't even worth considering.
Also avoid distributions with maintenance periods that might change. An enterprise-grade Linux distribution needs to be well organized. If it only relies on an open source project, the project might split up or be acquired by a vendor, eliminating your support lifetime.
The different prominient OS include>
Red Hat Enterprise Linux. Red Hat has an estimated market share between% and% of enterprise distributions. RHEL entered many data centers via support deals with hardware and software vendors, an approach emulated by other Linux distributions.The company employs more developers than other supported-Linux vendors. Therefore, Red Hat plays an important role in many open source projects. If your company wants to adopt cutting-edge open source platforms, it makes sense to standardize on Red Hat.
Red Hat offers many products that can be used to provide a complete open source infrastructure, notably Red Hat Enterprise Virtualization and Red Hat Cloud. Red Hat also provides the JBoss middleware platform, which corporate IT teams use to develop applications.
SUSE Linux Enterprise Server. SUSE estimates that about% of corporate Linux users run its SLES distribution, making it the second-largest supported Linux OS.
SUSE focuses on specific business verticals and partners with other major industry vendors like SAP and VMware. VMware customers get SLES free with VMware ESXi, and SUSE is the preferred platform for SAP. Microsoft also endorses SLES for its customers that need to use Linux, and has renewed that support through. That interoperability partnership started in and led to Microsoft introducing SUSE Linux to its customer Wal-Mart Stores Inc.
From a technical perspective, SUSE Linux is more accessible than the other supported Linux distributions. SUSE is also the most administrator-friendly. Its integrated YaST platform makes complicated management tasks on Linux easy to perform. SUSE is the main developer on Pacemaker High Availability, the standard tool for high-availability clusters in all current Linux distributions.
Ubuntu LTS. Ubuntu started as a free distribution. Canonical, the company backing Ubuntu, came along later to offer professional services around the distribution. Companies that want to run Ubuntu LTS in a supported environment should contract with Canonical, but those that are solely interested in using the software and getting updates for a guaranteed amount of time can download and install Ubuntu for free.
When installing Ubuntu as a server platform, use the Long Term Support version. Patches will be available for at least seven years for LTS, where the availability of patches for regular versions, which come out on a faster update cycle, is much more limited.
Ubuntu's desktop OS is famously easy to use, but that is not so with the server version. Most management tasks are performed the hard way, by modifying configuration files, running commands and starting processes. For some users, this is a real disappointment. Ubuntu is based on Debian Linux, a distribution popular with developers and in educational environments. Debian doesn't offer enterprise support, but by using Ubuntu LTS, customers can get it anyway.
Oracle Linux. Oracle's Unbreakable Kernel started by modifying the open source RHEL software to make a platform for Oracle databases.
Apart from companies that are running Oracle databases, Oracle's distribution hasn't been a huge success. It typically comes into the data center if the database administrator decides which Linux OS to use. Even still, many companies already have a Linux policy and a standard distribution that predates Oracle's open source initiative. This means plenty of Oracle databases still run on SUSE and Red Hat distributions, where it is supported.
Apart from Oracle VM, a Xen-based virtualization platform, Oracle doesn't have many open source products to complete its platform. Oracle also owns the Solaris operating system, which makes Oracle Linux less important.
So to come to a conclusion which is best from the available options it would be Redhat as it is the best choice for companies that need a server platform to run their own applications. It's also the winner for many companies because it's the biggest and strongest brand. Even if, from a technical or integration perspective, a company might be better off using SLES or Oracle Unbreakable Kernel, they stick with RHEL because it's reliable software from a reliable company.
But oracle DB is the one you looking to run then go for the Oracle Linux & if price is a major factor along with ease of administration alongwith blending in the Microsoft Products then SLES is the one can look upto.
RHEL6/7 rules the Linux Server industry may it be Oracle DB with SAP Integration.
However with SAP HANA in place, SUSE is the very next contender..
Ubuntu has some miles to cover ...
Sure Redhat Operating system is one of the most powerful server role Operating system but you supposed to pay for support , so if you need free operating system and redhat based ,you can go to CentoOS one of the best and totally free , powerful system ,stable and (Redhat Based :) )
Debian of course, stable as a rock, releases are based there on software integration and stability not time, there will be a delay between latest software and debian repos but just because it never crashes.
UBUNTU IS THE BEST ONE Operating system for Server Role
