What is linux server operating system

Linux Server Operating Systems Most Widely Used Run Business Apps

Most basic thing is to know Why we call Linux Operating Systems in two different things one Desktop Operating systems and Server Operating Systems. Linux Server (s) are used to produce high computing/performance power, because host hardware is more powerful (High Configuration) then Desktops.

What is Linux Server .?

Basically server is a high configuration computer which provide services to clients over network. Example: Web Server. Host Web Services in Linux Server and use it from many clients.

Linux Server Operating Systems

First of all how an Server and Desktop operating systems are segregated based on what parameters. There are few parameter which any business (Industry/Company) Looks for, based on qualifying those features/parameter we consider OS is Server Operating system.

In Linux very few are designed for Linux Server Operating Systems

• Cost: Any Business/Industry first think about investment cost. Most of the Linux Server (s) are open-source, so that buying/adopting cost will reduce comparatively Windows OS. Because you can freely download and install Linux Server Operating systems but only you need to buy support (For more details Read GNU terms). Of course not free if you want to re-distribute.

• Scalability: Start as a small level and expand to any level. While starting business you don’t need to buy huge configuration servers, later when business expands along with the business your applications/servers need to expand. Linux Server has super scalable capacity.

• Stability: Another expectation is applications/servers should always stable. Once Linux server is moved to production it does not required to shutdown/reboot until an unless there is an need (Power Outage).

• Security: Now a Days most required is security. Linux Servers are by default secure if you install with harden (Only required things in it). SELinux , Firewalld and File & Directory level permissions are controlled by super administrator (root).

• Support: If any problem with designed Operating System(s) support team should fix errors proactively.

• Multitasking / Multi User: Basically Server Operating systems are designed to support Multiple task execution / Multi User support at the same time. Task execution can’t be wait for current task, all task will be executed as soon as they get the resource from resource pool (Depends on Hardware Configuration).

• Networking: Of Course it’s mandatory to have as many as integration support with multiple applications (As Industry grows). It should support all most all TCP/IP protocols and UDP protocols to communicate with multiple devices around the internet cloud.

Here are Few Linux Server OS’s

Red Hat Enterprise Linux

• Protect your data with military grade security
• Maximum Up time
• Multi container-based applications across enterprise
• Deliver High Performance, toughest workloads immediately
• Works with Heterogeneous platforms

Ubuntu Server

It is always at the top of most Linux-related lists. Ubuntu is Debian-based and is undoubtedly the leading standard in the industry. Ease of installation quality commercial support and excellent hardware discovery means Ubuntu’s standards is hard to match.

• Instead of Using Swap Partition it uses Swap File
• New Release Ubuntu 17.04 (Zesty Zapus)
• Kernel Version 4.10
• Updated Versions of QEMU, Libvirt and DPDK
• Driverless printing enabled

Centos

This is popular operating system for web hosting companies around the globe. Centos is clone of Red Hat Enterprise Linux with extended repository support. CentOS Linux is no-cost and free to redistribute.

Fedora

Fedora Server Edition is an ecosystem ideal for creating and operating validated service roles addressing most computing needs.

Slackware

Slackware is one of the earliest available Linux server distributions. It was released first in 1993 and since then, it has grown an extensive fan base. Slackware is not associated with commercial distributions but it maintains relationships with many companies that offer fee-based support.

CoreOS

We think open source works best when it is treated like Linux or Apache httpd, basic infrastructure that we all share with very little direct commercial motives.

We want our open source components, things like etcd, rkt, flannel, and Container Linux, to be freely used, even if by a competitor. To that end, we want to make sure CoreOS serves a single purpose for our users: the place for open source tools that are the fundamental building blocks of modern distributed systems.

Oracle Enterprise Linux

This will come as a surprise but Oracle does indeed run an in house Linux distribution. Formerly known as Oracle Enterprise Linux, this is Red Hard Enterprise Linux made stronger by some nifty additions from Oracle. Oracle’s Linux competes directly with Red Hat’s Linux server distributions and it has been able to keep doing so effectively. Free to Download and Easy to Use.

ClearOS

• Ease of Use. Installation and Setup is made easy.
• No Additional Cost. ClearOS is Pre-loaded.
• Aimed for Small Business Industries

Arch Server Linux

Arch Linux is a simple and lightweight Linux distribution designed with more competent Linux users in mind. It may not offer the same level of support and ease of use as can be found in other Linux sever operating systems on this list, but it has effortlessly functioned as a viable server for many more experienced administrators.

Suse Linux Enterprise Server

SUSE Linux Enterprise Server is a world-class, secure open source server operating system, built to power physical, virtual and cloud-based mission-critical workloads. SUSE Linux Enterprise Server (SLES) is owned by Micro Focus but operated independently. It is a good option for businesses without the time and patience for lengthy troubleshooting calls. SLES is another distribution that focuses on stability and support as against leading-edge technologies and features.

• Transform Software-defined Networking & Network Function Virtualization
• Meet strict security requirements of the Federal Government (FISMA)
• Adapt to new technologies—ARM AArch64, Raspberry Pi & Omni-Path
• Easy access to the latest packages/technologies using SUSE Package Hub integration with SUSE Customer Center (SCC)

What is a Linux server?

A Linux server is a server running a variant of the Linux open source operating system (OS). It is designed to handle the most demanding business applications, such as web services and databases.

Linux servers provide a strong foundation for complex, enterprise-level data centers and workload environments, ranging from bare metal to virtual machines, and containers, including private or public clouds. They can also guide your digital transformation journey and cloud app development, with the capability to increase productivity, deliver services faster, and incorporate software innovations like cloud, containers, and configuration automation.

What is a Linux server?

At its core, a Linux server consists of Linux, a family of free, open source software operating systems built around the Linux kernel. The Linux OS was created as an alternative, free, open source version of the MINIX OS, which was itself based on the principles and design of Unix. Linux servers have gained popularity due to their stability, security, and flexibility. These are also among the key features that differentiate Linux servers from their proprietary counterparts.

The fully open-source nature of Linux helps keep setup and maintenance costs low, and it provides increased flexibility when it comes to setting up, operating, and maintaining a server. Users also get the benefit of the open source community and resources. As a result, many enterprises have adopted Linux servers to tap into this functionality.

A Linux server OS provides the central interface for user management and implements various security and administrative services–all key to operating in a client-server architecture.

Why use Linux servers?

Linux servers have the largest install base of all general-purpose operating systems. Linux is also the leading OS on servers, and very popular on mainframe computers, and it is the only OS used on TOP500 supercomputers.

Enterprises with applications serving thousands of users should consider adopting Linux servers. As IT infrastructure scales for the future, a Linux server provides platform manageability and flexible integration to help ensure a seamless transition, all while remaining compatible with legacy management and automation infrastructure.

Ever-changing scope, security, and management requirements also make avoiding downtime more important than ever. Linux servers have virtually no downtime. This gives software developers a degree of control when creating software-as-a-service (SaaS) tools or live applications, including the ability to handle multiple applications on a single server.

For IT staff, they don’t have to rely as heavily on hands-on management, and they can control and optimize permissions for enhanced security. Linux servers primarily run on the command-line, which makes them lighter and able to run on both physical and cloud servers. They can also help maximize overall system performance and simplify the management of repositories (i.e. Docker, MySQL, etc.), storage, containers, and more.

Why Red Hat Enterprise Linux Server?

To deploy in physical, virtual, and cloud environments, you need a comprehensive and scalable operating system. Red Hat Enterprise Linux Server orchestrates hardware resources and runs on physical systems, in the cloud, or as a hypervisor guest. It serves as a foundation in IT infrastructure supporting all major hardware platforms (x86, ARM, IBM Power and Z), as well as many of the leading workloads and applications like Oracle Database, SAP HANA, and Microsoft SQL Server.

Red Hat Enterprise Linux Server provides the standardization needed to build the infrastructure of your choice and expand as you see fit. It standardizes development and deployment with repeatable, flexible, scalable, and automated images, patch management, and backup processes. It also has built-in manageability and integration with broader Red Hat management and automation solutions that can help you optimize IT staff workloads, increasing efficiency and reducing unplanned downtime.

The Red Hat Enterprise Linux Server subscription model lets you choose the basis on which you purchase, stack subscriptions to streamline purchasing, and move subscriptions from physical to virtual to cloud and back to adapt to changing requirements.

With thousands of certified hardware, software, and cloud partners, Red Hat Enterprise Linux Server offers a consistent foundation across hybrid environments, supporting virtually any workload and providing the tools needed to deliver services and workloads faster with less effort.
