Access scientific knowledge from anywhere. SaaS, Styles, Component-Based, Scalability, Performance, Engineering 1 Problem In forward engineering, software architects plan, model, and analyze the high-level design of large software systems, i.e., their architecture. • By using multi-tenant and meta-data driven architecture Tenants can operate in virtual isolation Software as a Service (SaaS) is what most people mean when they say "the Cloud." As a result, a 7-dimensional cloud pricing framework is proposed that helps clarifying the possible pricing models in order to let companies differentiate themselves from competitors by price. Planning a suitable pricing strategy in early stages of the service development life cycle is highly significant since pricing may give special requirements to the architectural design, such as scalability and customizability. In this paper, the concept of SaaS software, the architecture of this kind of applications, their distribution models and long-term use costs are analyzed, and this approach is compared with on-premises software in the above issues. However, for software providers it is challenging to ensure a profitable revenue stream when a license fee is replaced by a periodic rental fee.

In this paper, the SBIFT pricing model is evaluated and up-dated to cloud context. 357, Software Business, Springer, 2012, pp. 53, no. According to Gartner, Software as a Service (SaaS) is "software that is owned, delivered and managed remotely by one or more providers.The provider delivers software based on one set of common code and data definitions that is consumed in a one-to-many model by all contracted customers at anytime on a pay-for-use basis or as a subscription based on use metrics." Applying multi-tenancy lowers the customizability, consequently the customers' negotiation power decreases. In the new era of computing, software can be sold and delivered as a cloud service, and software renting has become as a strategic tool to compete in the market. Self-defining data and business logic make the generated cloud services flexible. Each type of utility service is shown with an example which is interrelated with the engineering college scenario. The conclusions drawn with respect to related work and the results obtained shed more light on the application of public cloud systems for Software as a Service purposes. endobj Eng., vol.
