While rumors of Twain’s and the mainframe’s demise may have been greatly exaggerated, 32-bit is facing real death. I must have missed it when it released last October, but Windows Server 2008R2 is only available in 64-bit.
It’s been speculated and talked about for a while now, but it appears it has finally happened. I suspect no one disagrees that 64-bit is the future, but I doubt many of us are ready for the immediate termination of 32-bit servers. This is a major thorn in the side of SMBs and even large IT shops hit hard by the recession who have legions of server models that cannot handle the 64-bit OS. Then of course, the support ramifications will be significant… it will take Microsoft, component vendors, and ISVs years to eliminate all the compatibility issues.
Maybe M$ felt like they had to draw a line in the sand. I guess the technologist in me reluctantly agrees, but The IT Manager in me shudders.
