Commercial UNIX- and Open Source Linux- Variants
 

Emergence of UNIX and Linux

UNIX and Linux operating systems have emerged as a platform capable of supporting and being used on a variety of hardware architectures. Commercial, open source, and no-cost distributions of UNIX and Linux provide cost control and flexibility in long term planning. The first generations of the UNIX operating system in the early 1980's were used primarily as servers in business enterprise and as workstations in academic and engineering environments. It took years for UNIX to gain acceptance in commercial use and this breakthrough resulted from high reliability and price/performance advantages, not the availability of applications.

Ultimately, this led to broad adoption of RISC/UNIX systems. Both Hewlett-Packard and IBM arrived at the decision to develop and extend a UNIX-variant operating systems for utilization on their own proprietary hardware platforms. Sun Microsystems developed Solaris-UNIX to run on both its SPARC hardware and other types of hardware, including x86 servers and PCs. POSIX was developed to provide standardization across the UNIX-variants. Over the past decade, Linux deployments have to a significant degree been replacing UNIX in system infrastructure software. The Linux kernel is used in the leading Linux-variant operating systems: Red Hat, SUSE, and Ubuntu.

IBM Corporation's strategy extends its mainframe computing strengths in security and always-on availability and makes extensive use of both UNIX and Linux. Improvements in performance and energy efficiency aside, the most significant change with the new IBM mainframe hardware is data center integration. This design provides for blending tasks and parceling out parts of a complex application. The data and transaction is managed on the mainframe with the real-time processing performed by a UNIX or Linux computer system.


UNIX and Linux Server Operating Systems

All versions of UNIX combined - IBM AIX, HP-UX, and Oracle Solaris have approximately 10% of the market share. Marketing studies indicate that IBM's AIX UNIX is currently the most reliable and highest rated server operating system. Linux market share represents approximately 30% of the installed base. Linux overall reliability has improved substantially. The three leading distributions, Red Hat Enterprise Linux, SUSE Linux, and Ubuntu Linux, score high in reliability and have achieved near parity with UNIX distributions. Microsoft Windows Servers account for about 60% of the worldwide server operating system market. There is far less disparity in the number and severity of unplanned outages and actual downtime that organization's experience on standard UNIX, Linux, and MS Windows platforms.1

CETi technology partners report that most organizations utilize commercial distributions in combination with free no cost distributions of Linux.


Linux in the Mainstream

The selection and utilization of the Linux operating system has resulted from 1- reliable code, 2- low cost, 3- enhancements to the x86 server, workstation, and laptop hardware. Linux has become a mainstream solution for supporting deployments of business-critical workloads and business-oriented applications across a variety of hardware architectures. The initial Linux operating system incrementally replaced the infrastructure workloads being performed by UNIX or MS Windows servers. Linux has a substantial and growing use as a base platform for servers, database, middleware, and web application services.

Operational infrastructure and client support requirements have led to implementations of Linux by leading hardware and software companies such as Amazon, eBay, Google, Motorola, and Twitter. These companies are also investing in Linux to develop cloud computing operations. Dell and Hewlett-Packard market Linux-based desktop and laptop computers. Hewlett-Packard also has invested in HP-Linux and open-sourced its Linux-based webOS mobile operating system. Application software providers and ISV: Independent Software Vendorís support the Linux platform and promote deployment.

Market studies project a steady growth for Linux; it is being driven by the reliability of Linux-variant server and workstation operating system code, data center virtualization, cloud computing operations, and software which allows Linux to run Microsoft applications. The shift in workloads to Linux operating system deployments will continue.


Microsoft Software: Competition and Integration

Microsoft has been in a longstanding competition for migrating UNIX to its MS Windows Server and Windows family operating systems. The Microsoft UNIX migration readily can be applied to migrating Linux-variant operating systems. Microsoft has extended the featureset of the Windows family operating system, Windows Server 2008/2012/2016, SharePoint Server, and PowerShell for integration with the leading Linux-variants: Red Hat, SUSE, and Ubuntu. SUSE has been designated by Microsoft as its preferred Linux-variant. Linux administrators can use MS Windows Server Group Policy to expedite deployments and patch installations on SUSE and other Linux-variant operating systems.


Google Android and Chrome Operating Systems

The immense growth of mobile computing devices - smartphones and tablets also is driving the adoption of the Linux operating system. Google Corporation has brought to market two Linux-based operating systems: Android and Chrome. The Google strategy is based upon the assumption that the operating systems address different markets: Android for mobile computing devices and Chrome for software as a service and cloud computing.

Google acquired the Android operating system from Android, Inc. It is a Linux-variant operating system for use on mobile computing devices; it is a major component in the Google Corporation strategy to provide a unified mobile world. Android is open source software and has been made available to third party smartphone hardware manufacturers. This approach has served to make Android the leading operating system for smartphones at the low to middle range of the market. Android also has been adopted as the base platform for specialized Amazon and Barnes and Noble tablet devices and e-readers. In 2011, Google acquired Motorola Mobility, a maker of Android smartphones and tablets. This provides Google with the patents and hardware manufacturing capability to emulate portions of the Apple business model by designing its own models and integrating the software with the firmware. Its goal has been to compete with the Apple iPhone and iPad with improved Android smartphones and tablets. Derived from the OS X operating system used on Apple computers, the iOS is a UNIX mobile operating system used on iPhone and iPad devices.

The Chrome OS has been developed from a version of Ubuntu-Linux and has been designed and coded by Google. The target audience for Chrome is computer users spending most of their time on the Internet. It's functionality has Internet applications and web apps executing through a web browser. Google executives have suggested that over time the two systems will likely converge. However, the two operating systems have been built from different code bases. Despite the growing convergence of the devices, this will issue will become more problematic as new hardware is brought to market. At the current time, Google Chrome is clearly a work in progress.


UNIX and Linux Training by SYS-ED

SYS-ED knows UNIX and Linux. And equally as important, we know how to teach UNIX and Linux. Our consultants were among the original cadre of UNIX proponents and practitioners.2  We developed and taught C programs to a generation of programmers, were involved with the superset of functions which became C++, and wrote handouts and instructor guides for X Windows and Motif interfaces.

SYS-ED teaches:

  • Industry standard Solaris and Linux curriculum.
  • Migration from a Microsoft operating system and UNIX operating systems to Linux.
  • Scripting in UNIX- and Linux- variant platforms.
  • UNIX and Linux programming and utilities courses for application developers: C, Bourne Shell, and Korn Shell.
  • Oracle database, WebLogic Server, and Java application development on UNIX-Solaris and Linux-variant operating systems.
  • DB2 and WebSphere MQ on both UNIX- and Linux-variant base operating system platforms in IBM mainframe and distributed environments.
  • Linux in conjunction with Google Android and Web Apps.
  • Guidelines for service oriented architecture on the IBM mainframe, Oracle, and MS .NET platforms.

In UNIX and Linux courses, students learn by doing: installation, configuration, administration, problem resolution, and scripting. After a course is over, students are welcome to ask questions which come up back on the job. Specialized courses and integrated programs can be conducted on-site at the client location.

New courses are being developed for teaching Linux as a base platform and component in virtualization and cloud computing infrastructure.


Courseware Superior by Design

Reference material which explains and demonstrates is fundamental to an effective training experience. The consensus is that the documentation provided with open source software does not provide quality and completeness comparable to commercial software. In order to address this shortcoming and the scarcity of up to date industry standard UNIX and Linux textbooks. Computer Education Technique reviews information in the public domain distributed by purveyors of open source software, international standards committees, and software companies. We perform our own independent analysis of white papers, benchmarks, and software updates. Subject matter is then selectively incorporated into our student handouts. 3

In conjunction with presenting an instructor-led course at the client location, courseware is organized for subsequent use in a web-based infrastructure and delivery medium.


Qualifying a Training Assignment

SYS-ED will not accept a UNIX or Linux training assignment without a consultation with the prospective client organization. We review the background of the employees to be trained, operating environment, documented standards, and project specifications, and then use that information to select the code snippets, examples, skeleton programs, and hands-on exercises. We then prepare a training strategy: lesson plan, modular courseware, training aids, and validation assessment. And when not confident that a superior training outcome can be provided, SYS-ED will politely turn down an assignment.


Courseware for Teaching

The courseware used in SYS-ED courses consists of modular extensible student handouts, training aids, and industry-specific examples and exercises. At the client discretion an industry standard textbook and accompanying presentation slides can be utilized. The CETi knowledge base aggregates and analyzes information in the public domain. It also is a service for reviewing and answering questions. Content selectively is added to courseware.

In relation to a UNIX-variant operating system, Linux can provide a lower total cost of ownership and better return on investment. Migration to Linux typically allows for operation with fewer CPUs and results in annual savings on software database licenses. There are Linux-variants which can be used on the same hardware platform as an existing UNIX base operating system. This can be a significant advantage when managing virtualization and logical partitioning across both UNIX and Linux operating system platforms. Remaining on a hardware platform also removes issues associated with endianness.

Most UNIX operating systems are a complete operating system with the code, applications, and utilities provided by a single source or vendor; there is a commercial license with contractual requirements, charges, and restrictions. There are indications that changes may be occurring with the UNIX software model; OpenSolaris UNIX is available free of charge. The Open Group manages the UNIX trademark licensing program.

IBM AIX, Hewlett-Packard HP-UX, and Oracle Sun Solaris are the leading UNIX operating systems; each has hardware platforms. IBM and Oracle UNIX operating systems were designed initially to be integrated with product line strategies. There are significant differences in the kernel, configuration, process management, virtualization, performance, and tuning. From an operational standpoint, there can be a degree of hardware vendor lock-in associated with the UNIX operating system.

A firewall is not a standard inclusion in the UNIX operating system; it may be necessary to purchase third party software. Generic UNIX tools used for backing up the system portion of data will not work on Linux distributions. UNIX and Linux have different sets of tools for backing up data to tape and other backup media. Although there are common tools used in both operating systems, problems have been reported when using generic UNIX/Linux utilities such as tar and cpio between different platforms. Both UNIX and Linux provide a system initialization script; however, they are located in different directories.

The Linux kernel and operating system has been built upon and coded from the UNIX architecture and code base. It was written by Linus Torvalds with assistance from a dispersed team of programmers. Developed based upon open source principles, Linux provides modularity and independence from a commercial software vendor for an organizational enterprise to establish and manage its own operating system deployment and patches.

Linux distributions include a: 1- GUI: graphical user interface system 2- GNU utilities cp, mv, ls, date, bash, etc. 3- Installation and management tools 4- GNU C/C++ compilers 5- Editors (vi) 6- A variety of applications such as Firefox web browser and OpenOffice suite. Linux is available for download free of charge; it also is selectively redistributed under a GNU: General Public License. Linux comes with a open source netfilter/iptables based firewall tool for protecting a server and desktop. The independence of the Linux kernel and its inclusion in the GNU General Public License provides flexibility and alternative Linux-variant base operating system choices for implementation into an existing software infrastructure. Linux can be installed on x-86 desktop and servers, HP Itanium, X64 AMD Opteron-based systems, Sun Ultra SPARC, and IBM Power and mainframe systems.

There is significant free and commercial fee-based community support for the leading Linux-variant distributions: Red Hat and Fedora Linux, SUSE Linux - Micro Focus and Attachmate Companies, Ubuntu Linux - Canonical, and Android mobile device operating system - Google.
