Software as a Service

Cloud computing was a completely new term a short 9 years ago, in 2007. The basis of this technology is to move the workload of IT activities away from an organization, and to one or more third parties that have resources dedicated to processing such things. These can be, but are not limited to, networking, storage, software systems, and applications. Rather than having to create and maintain their own expensive datacenters, companies can pay a fee to use someone else’s. This makes growing businesses extremely flexible, as they can easily gain or remove storage space per their needs. Being able to purchase the use of online storage space is known as “hardware as a service,” or, more simply, “virtualization.” Being able to purchase the use of online software is known as “software as a service.” Both are very powerful tools that allow the minimization of a company’s IT budget.

SaaS, Software as a Service is the software, which is being deployed and provided over the Cloud environment (Grance, 2009). It represents one of the biggest Cloud markets and is growing exponentially fast (Rouse, 2016). The web is being used so that applications can be delivered, which are thoroughly managed and organized by a third party vendor and whose interface is undeniably accessed on the client’s side. The majority of the SaaS applications can be run directly from a web browser, needless of any downloads or installations. Some plugin’s requirement would be there, though. Blaming to the web delivery model, there is a well-noted eradication of the need for installation and process of application’s running on individual computers by SaaS. Some imminent examples of SaaS are: Google Apps, Salesforce, Workday, Concur, Citrix GoToMeeting, and Cisco WebEx

Because of their background, knowledge of the billing systems and understanding of the market needs, they were well aware of the “Software As A Services (SaaS)”, its future as well as the opportunities and the obstacles. They had also envisaged the market need for an efficient billing system. Their vision was to provide an e-commerce platform that powers the service industry at a low cost

Cloud computing offers services to users based on on-demand self-service, broad network access, measured service, resource pooling and rapid elasticity; These characteristics promise a faster time for implementation, lower cost, superior scalability and a better end user satisfaction. These services are delivered in models known as Software As A service (SaaS), Platform As A Service (PAAS), and Infrastructure As A Service (IAAS). The first layer which is the Software As A service (SaaS) is the layer in which software applications are delivered to end users. Below is the Platform As A Service (PAAS) layer which offers a platform on which applications can be developed. The lowest layer is the Infrastructure As A Service (IAAS) layer, in this layer the physical servers and network infrastructure is offered as a service. These services can be deployed throughout the internet (Public Cloud Computing), on the intranet infrastructure, (Private Cloud Computing), in a shared community of private networks (Community Cloud Computing), or a hybrid of both (Hybrid Cloud Computing). The service deployment models are [8]:

Salesforce.com (NYSE:CRM) is the world leader in Customer Relationship Management (CRM) software specifically designed for small and medium businesses, enterprises and government organizations. Salesforce.com was the first enterprise software company to break the $1B barrier of CRM sales on the cloud computing platform (Salesforce Investor Relations). It is also the first company to successfully orchestrate complex product and services strategies entirely on the Internet. This company's ability to orchestrate connectivity, cloud integration, enterprise storage and enterprise-wide applications is revolutionizing the economics of cloud computing today (Hedgebeth, 49). The strategic direction of the company is to expand quickly off of its sales base of applications, into customer service and support (Salesforce Investor Relations). As research studies from Gartner have shown, the majority of software sales in CRM today are in Customer Service and Support (34%) followed by Sales (26%) and Marketing (20%) (Salesforce Investor Relations). Salesforce.com reported $3B in revenue for their latest fiscal year and a $270M loss. Salesforce.com's success in enterprise CRM against entrenched competitors including Oracle and SAP is noteworthy, as both of these competitors rely on an on-premises application delivery model. The on-premises model is significantly more time-consuming to implement and often requires companies to

SaaS, or Software as a Service, portrays any cloud administration where buyers have the capacity to get to software/programming applications over the web. The applications are facilitated in "the cloud" and can be utilized for an extensive variety of errands for both people and companies. Google, Twitter, Facebook and Flickr are all samples of SaaS, with clients ready to get to the administrations by means of any web empowered gadget. Endeavor clients have the capacity to utilize applications for a scope of necessities,

Abstract. Software-as-a service (SaaS) is becoming popular in the modern era of cloud computing. Most of the organizations prefer to use SaaS instead of on premise software applications. This brings the responsibility of supporting a large number of tenants by the software vendor. A good approach for handling multiple tenants is to implement multi-tenant architecture for SaaS. Multi-tenant SaaS application will run a single instance of the application for all the users while providing enough customization options to tenants so that they feel like they are working on a dedicated application. Nevertheless, implementing the multi-tenant architecture effectively is a complex task as a lot of challenges and implications are involved in the

maintain full control of applications and data on local servers [1]. This is very important

SaaS applications offer wide range of configuration options and development environments that allows clients to set up their own additions and modifications.

Software as a Service (SaaS), sometimes referred to as "on- demand software" is a software delivery model in which software and associated data are hosted on the cloud. SaaS is typically accessed via a web browser and is paid on a subscription basis, monthly or yearly as per requirement.

SaaS is becoming an increasingly prevalent delivery model as underlying technologies that support Web services and service-oriented architecture (SOA) mature and new developmental approaches, such as Ajax, become popular. SaaS is closely related to the ASP (application service provider) and On Demand Computing software delivery model
