Outline

Explain briefly functions and feature.

fog provides a consistent, simple interface to many cloud services. Whether utilizing computing, DNS, storage or other cloud resources, fog's simple interface helps new users get started quickly and easily, find the best provider for their needs, and migrate easily when those needs change. Because of it's open source license and the community built around it, fog also allows for quick extension of its interface when new cloud products and features are released.

Here are some resources that I found helpful and found inspiration from when I was writing the talk.

• How To Design A good API and Why It Matters by Joshua Bloch
• Albert Einstein Quotes from Brainy Quote
• The Art of Unix Programming by Eric Steven Raymond
