Clouds, Community Clouds or Managed Services?

Our July issue of Waters magazine has been up on our website for a few days now. This month, I looked at the new "community clouds" that are popping up in the financial services space. Major vendors such as NYSE Technologies and Reuters are layering a number of business applications and data set on top of their offering there by moving the user closer to the data rather than moving the data closer to the user. Is it true cloud computing? I'm not sure. Marketers have done a wonderful job muddying the definition.
