Linux was developed by Linus Torvalds and released in October 1991, as a free operating system back on the open source model for developing and distributing software. The Linux kernel is the core of the operating system, based on the Unix model and largely POSIX compliant. Having been originally developed for used on Intel-x86 based PCs, Linux has since been ported for use across a wide range of platforms with full 64-bit processor support.
Linux is now installed on more web based servers than other Unix and Windows server operating systems, holding a share of approximately 37% in 2016. The main distributions in use on servers are Debian, Ubuntu, CentOS, RHEL and Gentoo, although there are many other versions available. Linux is also used on most supercomputers, some mainframe systems and is the core of the popular Android operating system, used on many mobile devices.
Data Recovery for Linux File Systems
Due to its origins, Linux has always seen rapid development for supporting all hardware, from the most modern technology, right through to legacy devices, often developed by a small number of people collaborating together. This same development cycle has seen Linux file system support added over the years, although the base file system was originally the Extended File System, which underwent several iterations through to Ext4. Many other non-native file systems are supported, such all FAT variants, NTFS, HFS+ and many others.
Until recently Ext4 or Ext3 were the default file systems for a new Linux installation, but many distributions now use the XFS file system, originally developed by SGI for their Solaris operating system, before it was ported to Linux as open source code. ReiserFS was developed as another option for use with Linux, which proved popular for some distributions, but was never integrated into the kernel and faces an uncertain future.
Linux Server Data Recovery
Linux has proved to be perfectly suited for the server environment, due to its security and ability to connect with any other type of computer via a wide range of network protocols. The Logical Volume Manager (LVM) is now provided as standard, allowing multiple disk devices to be configured as a RAID array, which can be connected directly or made available via the iSCSI protocol.
This makes Linux server extremely versatile and easily upgradeable, therefore particularly suited for use as a network appliance, such as a web server or file server. Many versions of Linux are completely free to use, although at the enterprise level, support for the operating system can be bought.
Future of Linux
With the use of server systems, particularly for providing web servers and cloud storage space, use of the Linux operating system looks set to remain an attractive proposition. They have proved to have rock solid security, high reliability, are generally low maintenance and contain no lock-in clauses to tie you to a particular vendor. Linux is available for also available for a wide range of servers, allowing most existing hardware to be used if deemed necessary, ranging from diverse systems such as the Dec Alpha, Sun UltraSparc, IBM Z-System, Intel Itanium, HP PA-RISC systems and many others.
While Linux looks set to have only a small share of the desktop computer market, the requirement for ever more cloud storage space, web services and dedicated file servers, it is likely that the market share of Linux in the server market is set to increase.
