Introduction to Cloud Design

Version 1

    Cloud computing is a collection of technologies and practices used to abstract the provisioning andmanagement of computer hardware. The goal is to simplify the users experience so they can get thebenefit of compute resources on demand; or in the language of cloud computing “as a service”.The resources that comprise an individual cloud are generally made available to end users using aninterface that conforms to one of three levels of abstractions. From most granular to most abstract theseare Infrastructure-as-a-Service (Iaas), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS).
