Infrastructure platform comparison for Private Cloud solutions

For the Technophiles ….

There is a very large selection of cloud-based infrastructure available today. Do a Google search, and you will be amazed how many folks are offering these services. It feels like a crowded space, filled with confusing offerings. I came across the table below, which goes a long way towards helping me understand what each of the technology platforms offer, and the circumstances under which one works better than the other. I hope you will find this useful in your own forays into the new world of the cloud.

I also find it interesting that our ability to rent dedicated servers instead of virtual servers has been greatly enhanced. But watch out. Not everyone is offering you the ability to mix and match, or letting you manage it yourself with easy access to the console, and as always there are limitations. It all boils down to what you are trying to do and what would work best.
