fundamental characteristics

1. Customers get computing resources that are on-demand and self-service 
2. Customers get access to those resources over the internet, from anywhere
3. The provider of those resources allocates them to users out of that pool
4. The resources are elastic - which means they can increase or decrease as needed
5. Customers pay only for what they use, or reserve as they go 
6. All of cloud computing is available via web requests
