The Cloud
   - The Cloud is a set of technologies that support distributed
       storage and distributed processing.
 
   - There are lots of different clouds, and typically they make
       use of a lot of standard PCs.
 
   - Distributed databases are a simple example of distributed 
       storage.
 
   - Remember that there are a lot of security issues when you put
       your data in the cloud.  (It's not safe there.)
 
   - Of course, there's no reason a company can't use cloud technologies
       themselves.  They do need to keep it off the internet for safety.
 
   - The cloud is more than just storage, you can also do processing on it.
   
 
   - One obvious benefit is that you can process large data sets.
