Abstract
There are issues of confusion between the concepts of Service Oriented Architecture (SOA) and Software as a Service (SaaS) which affect on the benefits they offer like cost reduction and agility. To solve this problem, the paper aims to explore the concepts of SaaS and SOA in order to give better understanding of these two technologies. Since SaaS cloud is getting more popular day by day and many companies are shifting to apply SaaS solutions, this motivates us to make a clear understanding of the concepts of SaaS delivery model and SOA architecture. Therefore, in this research we have reviewed the concepts and features of both SaaS cloud and SOA and then compared them with the traditional on-premise software.
Highlights
The origin of computing resource sharing back to 1960’s when the idea of “computation should be organized as a public utility” has been proposed by John McCarthy in 1961
The results of the research indicate that Service Oriented Architecture (SOA) is a manufacturing model which deals with designing and building software by applying the service oriented principles, while Software as a Service (SaaS) is a model for sales and distribution of software applications
SaaS is a means of delivering software as services over the Internet to its subscribers, while SOA is an architectural model in which the smallest unit of logic is a service
