SaaS
. So, what is Software-as-a-Service (SaaS)? Generally speaking, any software application which is licensed for use on an on-demand basis could be classified as SaaS, however, the term SaaS is typically used to describe an application which is delivered via the internet and accessible through a web browser. In contrast to the more traditional software distribution model, SaaS applications seldom require that anything be installed on the user’s computer. Instead, everything required to interface with the application is downloaded each time the service is accessed. SaaS is actually one of the layers of the much talked about revolutionary model, Cloud computing. Cloud computing providers offer their services according to three fundamental models: Infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS) where IaaS is the most basic and each higher model abstracts from the details of the lower models. IaaS offer computers – as physical or more often as virtual machines – raw (block) storage, firewalls , load balancers, and networks. IaaS providers supply these resources on demand from their large pools installed in data centers. Local area networks including IP addresses are part of the offerThe cloud symbol was used to denote the demarcation point between that which was the responsibility of the provider and that which was the responsibility of the user. PaaS offer computing platform and/or solution stack typically including operating system, programming language execution environment, database, and web server. Application developers can develop and run their software solutions on a cloud platform without the cost and complexity of buying and managing the underlying hardware and software layers There are various deployment models applied like public, community, hybrid, Private etc. Agility, cost efficiency, virtualization, reliability, scalability, performance, less maintenance form the growing list of advantages, yet there are risks such as dependency on networks, security and centralization of data and computing.

Why Saas/cloud ecommerce? software-as-a-service (SaaS) ecommerce solutions allow small online retailers to open functional online stores with a minimum in capital expense. SaaS providers take care of the technological aspects such as mission-critical computing requirements from heavy seasonal business peaks or even unexpected promotional successes which can test even the best IT infrastructures. Hence the merchants can focus entirely on extending their brand, marketing products, innovation and achieving the key metrics of their online business success.
