I need some assistance with these assignment. why software as a service is going to dominate the next several years Thank you in advance for the help! These services can be broadly classified into three categories: Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). SaaS is by far the most widely used service of the cloud in today’s time and hence, cloud computing and SaaS are used synonymously sometimes even though SaaS is actually one of the services provided by the cloud. Considering the current trends, SaaS is most likely to dominate the next several years in the field of information management.
SaaS is a software delivery model often referred to as “on-demand software” in which the software and the required data are centrally hosted on the cloud and are typically accessed by the users over the internet using a thin-client such as a web browser. One daily life example of this is the famous Google Docs in which one is able to open Microsoft Word document files, PDF files within the browser itself without having to download the software to your computer and open the file using the installed application. The cloud computing concept is not actually new. Computing as a utility was developed as a part of MULTICS (Multiplexed Information and Computing Service) which was a time-sharing operating system developed way back in the 1960s. However, what is new in cloud computing is the illusion of infinite resources on demand, fine-grained billing, and the concept of public and private clouds. Also, the pay-as-you-go paradigm is what makes cloud different from the former ideas similar to cloud.
Cloud computing democratizes access to supercomputer capability. In the past, when researchers and scientists needed to perform extremely complex and demanding calculations, they needed supercomputers that had tremendous processing speed and very large memory. This would require a lot of monetary resources and the permission to use such supercomputers was only given to credible individuals. .
