A Cloud Model to Implement SaaS

Abstract

Cloud computing is a paradigm where tasks are assigned to a combination of connections, software and services accessed over a network. Clouds provide processing power, which is made possible through distributed computing. Cloud computing can be seen as a traditional desktop computing model, where the resources of a single desktop or computer used to complete tasks, and an expansion of the client/server model. The paper describes a model for cloud computing to implement software as a service (SaaS).

Enhancement of Online Course Development based on a Public Cloud Computing Infrastructure

“…Managed hosting and development environments are the services included in IaaS [2]. The user can buy the infrastructure according to the requirements at any particular point of time instead of buying the infrastructure that might not be used from months.…”

“…Significant innovations in virtualization and in the distributed computing, as well as it improved access to high speed Internet and a weak economy, have accelerated interest in the cloud computing. Cloud technology [2] wills provides computation, software, data access, and the storage services that do not require any end-user knowledge of the physical location and configuration of the system that delivers the services. Cloud technology providers deliver applications through internet, which are accessed from web browser, while business software and data are stored on servers at a remote location.…”

“…Instead of installing the software and maintaining software, we can simply access it through Internet, freeing ourselves from complex software and also from hardware management. SaaS [2] applications are also called Web-based software, or demand software, or hosted software. Whatever the name may be, SaaS applications run on a SaaS [5] provider's servers.…”

“…To follows the heels of SaaS, platform as a service (PaaS) [2] is another application delivery model. PaaS provides all the resources which are required to build applications and services completely from the internet without having to download any software or to install any software.…”

Efficient Use of Cloud Computing in Medical Science

“…Instead of installing and maintaining software, you simply access it via the Internet, freeing yourself from complex software and hardware management. SaaS [4] applications are sometimes called Web-based software, ondemand software, or hosted software. Whatever the name, SaaS applications run on a SaaS provider's servers.…”
