I have yet to receive any guest blogs specifically about educational technology since we opened up several of our columns to guest submissions. I thought it might bring some folks out of the woodwork, though, if I suggested a specific topic. Server virtualization is something with which I have very little experience and, until recently, has been too expensive for much of the ed tech market. However, as technologies mature and costs come down, virtualization seems to be a viable means for server consolidation and cost savings, both in terms of hardware and energy consumption.
As we all try to green up our server rooms and stretch budgets, this will become increasingly important. However, I have yet to find even a good whitepaper on the use of virtual machines in ed tech. If anyone out there has experiences in this area to share, especially in K-12 settings where serious backend horsepower is just getting a foothold, please upload a blog post for review and potential inclusion in this column.
