Unix to Red Hat Enterprise Linux

  1. 1. Unix 2 Red Hat Enterprise Linux Syed M Shaaf Solutions Architect February1
  2. 2. Linux Momentum Continues Expanded use in last 12 months 84% Continue in 82% year ahead “Plan to use Linux for 69% more mission-critical workloads.” Linux Adoption Trends 2012: A Survey of Enterprise End Users – A Report by the Linux Foundation in partnership with Yeoman Technology Group2
  3. 3. Linux Momentum Continues New applications and services 71.6% Migrated from Windows 38.5% In the last 2 years UNIX migrations 34.5% Linux Adoption Trends 2012: A Survey of Enterprise End Users – A Report by the Linux Foundation in partnership with Yeoman Technology Group3
  4. 4. Red Hat Enterprise Linux AdoptionIncreasing Many migrating to x86 UNIX/ Many migrating from UNIX RISC migrate to Red Hat Enterprise Linux 60% Paid Linux More applications,hardware, and device drivers on Red Hat Server units Enterprise Linux 97% shipped worldwide4
  5. 5. Preferred by ISVs, Deploy with Confidence ISV developers porting Open source = UNIX increasingly less likely Red Hat Enterprise Linux ● Deploy on multiple platforms with performance & reliability/availability features of enterprise UNIX5 ● Retain IT staff and skills
  6. 6. Why Migrate to x86 and Linux Increase choice of hardware, Legal, corporate compliance software, peripherals Hardware refresh Lower TCO, increase ROI Need to quickly adapt to change Cloud readiness Running IBM, SAP, or SAS EOL of database, operating system, hardware maint. Migrate to commodity, but Linux like tools, might as well retain skills migrate to Linux6
  7. 7. your logo hereWhy do People Select Linux?Lower total cost of ownership (TCO) 70%Features/technical superiority 68.6%Security 63.6%In-house talent experience with Linux 52.7%No vendor lock-in 52.5%Openness, ability to modify code 50.8%Long-term viability of platform 47.5%Choice of software 38.5%Choice of hardware 37.1%Linux Adoption Trends 2012: A Survey of Enterprise End Users – A Report by the Linux Foundationin partnership with Yeoman Technology Group
  8. 8. Reduce TCO Lower-cost Subscription only Predictable IT admins costs “Our analysis was correct as Taught in supporting the commodity all education hardware that Linux runs on is levels much more affordable than the ● Access to all shipping support that we needed to versions maintain proprietary hardware. ● Steady stream of The savings in support, both enhancements internally and externally, associated with Red Hat ● Proactive security Enterprise Linux is significant Used in updates governments for us.” around the ● Additional — Dean Abercrombie, hardware/software Cox Enterprises UNIX and storage8 world systems group manager support
  9. 9. Increase Choice Red Hat Enterprise Linux ● Apps certified certified on more platforms on RHEL than any other OS — from desktop to mainframe supported on KVM, Vmware, Hyper-V, Lpars ● 1000s of ● Application software isolation with and cGroups, hardware SELinux vendors sandboxes ● One of the ● Containers in largest RHEL 69 technology coming!
