Software as a Service (SaaS) refers to a model of software delivery in which applications are hosted remotely and made accessible to users over the internet. SaaS eliminates the need for local installation and maintenance, allowing individuals and organizations to access tools through subscription-based pricing. This approach often includes automatic updates, security management, and scalability, reducing technical overhead for end users. According to industry research firms such as Gartner, SaaS has become a dominant form of cloud computing, serving both consumer and enterprise markets. Companies including @Salesforce, @Zoom, and @Slack are widely cited examples of SaaS providers, offering services that integrate into business operations at global scale. The SaaS model supports diverse applications such as customer relationship management, communications, project management, and financial tools. Its architecture typically relies on multi-tenancy, where a single version of the software serves multiple customers, though customization and integration capabilities vary across providers. As organizations shift from capital expenditure to operational expenditure models, SaaS continues to expand as a cost-efficient and flexible solution
