The basic concepts and the technology behind the cloud like Virtualisation and server based computing been around for more than three decades. But rapid advances in the technology particularly processors ,storage and connectivity made it possible to “commoditize “ the computing infrastructure thus making a meaningful business model.
By definition it is the delivery of on-demand computing resources—everything from applications to data centers—over the internet on a pay-for-use basis. As computing evolved into a “service” , providers of such service can be grouped as,
Infrastructure as a service (IaaS): Infrastructure as a service provides companies with computing resources including servers, networking, storage, and data center space on a pay-per-use basis. IasS refers to real estate , power and the connectivity and may include hardware also.
Platform as a service (PaaS) :Platform as a service provides a cloud-based environment with everything required to support the complete life cycle of building and delivering applications. Essentially it means IaaS plus management or the orchestration software.
Software as a service (SaaS) :Cloud-based applications delivered to end users’ computers via the internet and, usually, a web browser.
