Cloudy with a chance of confusion

Cloud is very popular these day, one of the consequences is the number of terms and products which have the word Cloud in its name which causes a lot of confusion.
I'll try to collect here some of them.

• CloudFormation - AWS Configuration management tool, which uses templates with a special format.
• CloudStack - opensource software to manage VMs.
• CloudFoundry - cloud computing PaaS, some of the cloud providers (e.g. IBM Bluemix) are based on it
