What is SaaS?
Software as a service (SaaS) is a model for delivering applications as a service over the Internet. Instead of downloading and managing software, you simply use the Internet to access it, eliminating the need for complicated software and hardware management. Web-based apps, on-demand software, and hosted software are all terms used to describe SaaS applications. SaaS applications, regardless of their name, they are hosted on a SaaS provider’s servers. The application’s security, availability, and efficiency are the responsibility of the service provider.
SaaS Characteristics
Consider a bank that protects each customer’s privacy while offering dependable and safe service on a large scale to understand the SaaS model. Customers of a bank can use the same financial systems and technologies without fear of unauthorised access to their personal information. The main characteristics of the SaaS model are met by a “bank”:
Multitenant Architecture
A multitenant architecture is one in which all users and software share a single, centrally managed infrastructure and code base. Since all SaaS vendor clients share the same infrastructure and code base, vendors can innovate more easily and save development time that would otherwise be spent maintaining multiple versions of obsolete code.
Easy Customisation
Each user’s ability to easily customise applications to suit their business processes without disrupting the shared infrastructure. These customizations are special to each company or consumer due to the way SaaS is built, and they are often maintained by upgrades. As a result, SaaS providers can update their products more often, with less risk to their customers and a lower adoption rate.
Better Access
Improved data access from any networked computer, as well as simpler privilege management, data use monitoring, and ensuring that everybody sees the same information at the same time.
SaaS Harnesses the Consumer Web
The Web interface of typical SaaS applications would be familiar to anyone who has used Amazon.com or My Yahoo! You can customise with point-and-click ease with the SaaS model, making the weeks or months it takes to upgrade conventional business applications seem hopelessly antiquated.
SaaS Trends
SaaS integration platforms (or SIPs) are now being developed by companies in order to create additional SaaS applications. The “third wave” of software adoption, according to consulting firm Saugatuck Technology, occurs as SaaS moves beyond standalone software capabilities to become a forum for mission-critical applications.
