Supporting old systems
The recent Microsoft-sponsored whitepaper from IDC illustrates how businesses utilising Windows are navigating their infrastructure between significant versions. From the established Windows XP, skipping over Windows Vista, and ignoring the forthcoming Windows 8; it seems we should arrive at a place where Windows 7 dominates. There’ll be movement away from Windows XP as the 2014 support deadline nears, coupled with Software Assurance agreements to smooth a downgrade from Windows 8 to Windows 7.
Is that motion too slow? Almost certainly - look at the figures:
Annual cost per PC per year for Windows XP is $870, while a comparable Windows 7 installation costs $168 per PC per year. That is an incremental $701 per PC per year for IT and end-user labor costs.
Organisations need to understand how much of a drain Windows XP will continue to be, and work to determine how urgent a change is.
The simple fact is a migration takes colossal effort. Ask Google - the company moves between LTS releases of “Goobuntu” (a customised version of Ubuntu Linux) to keep their IT stable and standardised. Engineers like Thomas Bushnell have developed a process to reduce downtime, as he highlights - a reboot can cost as much as a million dollars.
These are migrations at massive scale, and represent problems that are almost exclusively tackled by large enterprises.
Back at my former employer, I spent a summer holiday upgrading the entire school from Windows Server 2003 / Windows XP to Windows Server 2008 R2 / Windows 7. Feedback from users formed a greater part of the change than tools and capabilities for administering the network. The pros: I unearthed a number of 64bit machines which ran blazingly fast and really wowed the kids. The cons: about a dozen software titles suddenly became unusable - mostly early years and special educational needs programs built for Windows 95, which upset respective teaching staff.
For SME’s, there are alternatives to a costly move - BYOD and rolling upgrades are plausible notions. To an enterprise, a largely unmanaged policy like BYOD chips away at fundamental principles of IT. But arguments like this, from an old post on Minimal Mac about Microsoft Office, suppose we’re ignoring another shift:
Microsoft’s biggest miss was allowing the world to finally see the truth behind the big lie — they were not needed to get real work done. Or anything done, really.
SME’s - which direction will you move?
