  • Introducing Linux on IBM Z Systems IT Simplicity with an Enterprise Grade Linux Platform
    Introducing Linux on IBM z Systems IT simplicity with an enterprise grade Linux platform Wilhelm Mild IBM Executive IT Architect for Mobile, z Systems and Linux © 2016 IBM Corporation IBM Germany What is Linux? . Linux is an operating system – Operating systems are tools which enable computers to function as multi-user, multitasking, and multiprocessing servers. – Linux is typically delivered in a Distribution with many useful tools and Open Source components. Linux is hardware agnostic by design – Linux runs on multiple hardware architectures which means Linux skills are platform independent. Linux is modular and built to coexist with other operating systems – Businesses are using Linux today. More and more businesses proceed with an evolutionary solution strategy based on Linux. 2 © 2016 IBM Corporation What is IBM z Systems ? . IBM z Systems is the family name used by IBM for its mainframe computers – The z Systems families were named for their availability – z stands for zero downtime. The systems are built with spare components capable of hot failovers to ensure continuous operations. IBM z Systems paradigm – The IBM z Systems family maintains full backward compatibility. In effect, current systems are the direct, lineal descendants of System/360, built in 1964, and the System/370 from the 1970s. Many applications written for these systems can still run unmodified on the newest z Systems over five decades later. IBM z Systems variety of Operating Systems – There are different traditional Operating Systems that run on z Systems like z/OS, z/VSE or TPF. With z/VM IBM delivers a mature Hypervisor to virtualize the operating systems.

Ubuntu on Big Iron: ubuntu-on-big-iron.blogspot.de Canonical We are the company behind Ubuntu. Where is the name Ubuntu coming from? ubuntu |oǒ'boǒntoō| Ubuntu is an ancient African word meaning ‘humanity to others’. It also means ‘I am what I am because of who we all are’. The Ubuntu operating system brings the spirit of Ubuntu to the world of computers. Ubuntu http://www.ubuntu.com/about/about-ubuntu Ubuntu Server for IBM Z and LinuxONE (s390x) Design Philosophy ● Expand Ubuntu’s ease of use to the s390x architecture (IBM Z and LinuxONE) ● Unlock new workloads, especially in the Open Source, Cloud and Container space ● Offer a radically new pricing approach (drawer-based pricing) ● Consequentially tap into new client bases ● Exploit new features and components faster - in two ways: ○ hardware: compiled for zEC12 and up ○ software: latest kernels, compilers and optimized libraries ● Provide party with other architectures ○ Release parity ○ Feature parity ○ Uniform user experience ○ Close potential gaps ● Open source - is collective power in action ● Upstream work and code only - no forks Ubuntu Release Naming Scheme The official name of an Ubuntu release is ‘Ubuntu x.y’ with ‘x’ representing the year (minus 2000) and ‘y’ representing the month of eventual release within in that year. So Ubuntu's first release, made available in 2004 October (October is the 10th month) was Ubuntu 4.10. Since the actual release date
