  9. 9. Delivering Software Maintenance Customers needs: - Maintain secure environment - Insure uninterrupted business operations - Minimize downtime - Reduce cost - Minimize the vulnerability window Vendor needs: - Bound the cost of delivery (non-core task, no value add) - Maintain rock-solid reliability, or customer satisfaction suffers 9 © Novell, Inc. All rights reserved.
  10. 10. Delivering Maintenance: Customer View How is this delivered? (traditional enterprise) - Vendor delivers patches (update stream) - Customer validates patch impact on test systems (integration testing) How is this delivered? (appliance model) - ISV integrates appliance - ISV integrates updates - Customer chooses downtime window, applies updates - One click! => ROI two-punch: customer saves initial integration cost, but also ongoing operational validation of the workload! 10 © Novell, Inc. All rights reserved.
  11. 11. Delivering Maintenance: Vendor View How is this delivered? (without Appliance Toolkit) - Amorphous stream of updates -- Packages if Linux - CDs, reinstalls, tarballs and often much worse if small vendor - Good customer experience always very costly – Need expensive, non-core expertise – Even smallest distros need 10+ people to insure quality – Maintenance is a pitfall-ridden space – Adds nothing to vendor value, a net cost! – But failures are devastating to your business credibility => If you know how hard it is, you avoid it (small vendor) or simplify it (medium vendor or internal provider) at the detriment of service 11 © Novell, Inc. All rights reserved.
  12. 12. Delivering Maintenance: Vendor View How is this delivered? (appliance model) - ISV Integrates appliance using SUSE Linux Enterprise platform ® - Studio and SLMS automatically generate update sets - ISV tests only full appliance – One version to test, not full matrix! – Integration testing cost collapsed from traditional model – Massive ROI – Yet improved user experience => If your customer's recurring operations embrace the appliance model, not just your deployment crew, the cost-benefit improves still 12 © Novell, Inc.
