The document discusses cloud computing concepts including definitions, characteristics, models, providers and pricing. Some key points discussed include:
- Cloud computing provides scalable computing resources as a service over the internet on a pay-per-use basis. Resources include servers, storage, applications and more.
- Cloud models include private, public and hybrid clouds. Providers offer infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS).
- Cost benefits of cloud computing include low startup costs, no need for on-premise IT staff, and pay per use pricing versus large upfront license fees. Managing multiple cloud contracts can be challenging for businesses.
