Chances are pretty good that if you are in charge of an IT department of a small or medium-sized firm, you will soon be faced with the dilemma:  To move to the “Cloud” or to stay with traditional software module.

When that time comes, you need to be prepared and know what the most popular SaaS vendors are out there and what services they provide!

I found a great list of the top 25 SaaS (Software as a Service) vendors here. For the month of January 2010 the top 5 are:

  • SAP Business ByDesign
  • GoGrid
  • StormOnDemand
  • CariNet
  • SoftLayer bases their picks based on the number of votes that particular company receives and the number of times it’s profile is viewed during the month.
