Software As A Service ( Saas )

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

As we learned in previous weeks, cloud computing services have three major different cloud architectures for different demanding customers. The three different architectures are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). For the words of the name, we can see the obvious differences among these three architectures, which they provide different cloud services based on their specific cloud architectures. What are the differences among these three cloud services? What are the responsibilities for the cloud services providers? What are the responsibilities for the customers? The following will discuss about these questions.

SaaS is generally acknowledged to have been acquainted with the business world by the Salesforce. Customer Relationship Management (CRM) item. As one of the soonest contestants it is not amazing that CRM is the most famous SaaS application range, however, email, budgetary administration, client administration and cost administration have likewise gotten great up

which often use these platforms to develop their services, and PaaS also allow third parties to

The providers computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical

When user has to use more than one infrastructure user need to pay more money for each cloud to use the facilities which makes the application expensive. [3]

Small to medium business are comfortable with the transition to SaaS, as this is seen as a trend towards Cloud computing

With the industry showing no signs of slowing down in SaaS, the key principle of successful SaaS business is often based on understanding the market and being able to offer the right type of product with a higher-value pricing model that brings more revenue in the long haul.

As of 2014, NetSuite was a leading provider of cloud-based financial and enterprise resource planning, as well as omnichannel commerce software. Cloud-based computing uses the internet to deliver applications and software companies from a remote server. By doing this, companies were able to eliminate the cost of installing and maintaining infrastructure used to store these applications and other services. NetSuite would typically charge a subscription fee for a pre-arranged amount of time. The companies that benefit from these services the most are medium-sized companies, as opposed to large enterprises. This is because the cloud applications require substantially less capital to build, maintain, and purchase software. Additionally,

Enterprise computing has evolved rapidly over the years and have brought ever increasing benefits to the organizations. They have also made the software systems complex and bulky. With the increased complexity of the software products, the infrastructure required to maintain and support the software have also increased. This ultimately drove the project costs higher. To encounter the growing costs, there have been several architectures that were proposed. One such solution which has gained enormous

In essence, this technology came about when the culmination of Internet Service Providers (ISP) developed the ability to host web services and create a virtualized infrastructure (MSV, 2012, p. 5). A virtualized infrastructure – better known as virtualization – is where multiple servers are consolidated (MSV, 2012, p. 5). For instance, an organization can have individual servers for each of the following “roles like Web Servers, Database Servers and Messaging Servers” (MSV, 2012, p. 4). Instead of having a plethora of servers to handle these many different roles each server is virtualized to take on multiple roles here by “the data center infrastructure can be consolidated from hundreds of servers to just tens of servers” (MSV, 2012, p. 4). Initially this technology was implemented in data centers as a means for organizations to lower a data centers total cost of ownership; therefore, saving companies significant amounts of money on power bills, cooling equipment, and hardware in general (MSV, 2012, p. 5). Although today 's cloud technology is widely developing into a product called Software as a Service (SaaS) (Srinivasan, 2013, p.48). In example, services like iCloud, Google Drive, or OneDrive from Microsoft are considered SaaS (Srinivasan, 2013, p.49). These examples offer a certain amount of free storage space for users who employ their services and have an account which is usually free as well.

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

No more hardware costs: In on-prem hosted services you need to retire outdated hardware on time to time, but with moving to Cloud no more hardware purchase required.

SaaS is a method of software that allows data to be accessed from any device with an internet connection. In the web-based model,

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
