Running Header: Virtualization and Cloud Computing World 2 Virtualization and Cloud Computing World SaaS is used to describe a model of software deployment that uses the web to deliver applications on an “as-needed” basis (Pearlson, K. & Saunders, C., 2013, pg. 385). It usually runs on a computer on the Internet, rather than on the customer’s computer, as is accessed through a web browser. PaaS is the set of tools and services designed to make coding and deploying those applications quick and efficient. IaaS is the hardware and software that powers it all – servers, storage, networks, and operating systems. Items that an organization IT/Is department should consider when an organization’s strategy calls for the use of SaaS, PaaS, or IaaS are: On demand Self-service – the ability for an end user to sign up and receive services without the long delays Broad network access – the ability to access the service via standard platforms (desktop, laptop, mobile, etc.)
