fog is the Ruby cloud computing library.
The quick and dirty, top to bottom:
* Models provide a simplified interface, making clouds easier to work with and switch between.
* Collections provide a simplified interface, making clouds easier to work with and switch between.
* Requests allow power users to get the most out of the features of each individual cloud.
* Mocks make testing and integrating a breeze.

== Collections
Nouns like Images and Servers are collections, which form the interface to the cloud.
A high level interface to each cloud is provided through collections, such as images and servers.
You can see a list of available collections by calling #collections on the connection object.
Some of these collections are shared across multiple providers.
The shared collections for compute resources are flavors, images and servers.
Shared collections for storage are directory and file.
Shared collections for compute are: flavors, images and servers.
Shared collections for storage are: directory and file.
Some common methods for all of these collections are:
* #all - fetch every object of that type from the provider.

== Models
Many of the collection methods return individual objects, which provide destroy, save and wait_for methods.
Many of the collection methods return individual objects, which also provide some common methods:
* #destroy - will destroy the persisted object from the provider
* #save - persist the object to the provider
* #wait_for - takes a block and waits for either the block to return true for the object or for a timeout (defaults to 10 minutes)

== Requests
Requests allow you to dive deeper when the models just can't cut it.
You can see a list of available requests by calling #requests on the connection object.
For instance, ec2 provides methods related to reserved instances that don't have any models (yet).
Here is how you can lookup your reserved instances:
