Introduction to Cloud Computing

Cloud Computing makes it possible for end-users to make better use of equipment and technologies used in IT and IT industries so that they can make use of the resources they want and pay only for them.

The Internet-based computing system can be characterized by many remote servers that allow shared data processing companies, centralized information storage, and online access to services or resources. The term ‘cloud computing’ is relatively recent. But, since 1996, when Hotmail and other web-based emails became more common, we have not been aware of the internet.

Cloud infrastructure has become a commercial concern with the advent of the market cycle of outsourcing IT and IT-enabled applications, various IT providers pledge to provide computation, storage and data hosting services and availability across several continents, provide Service Level Agreements (SLAs)-backed efficiency and uptime promises to offer services. Although these clouds are the natural progression from conventional data centers, they vary from the typical web-based infrastructure and a “utility” price model in terms of the usage of computing power, storage, and distribution of data by exposing resources (computation, data center, and applications). They charge clients according to their price model. This provides subscription-based access to the IaaS (Infrastructure as a Service), PaaS (Platform as a Service) and SaaS (Software as a Service) infrastructures, platforms, and technologies.
