Software as a Service (SaaS)

This type of cloud computing delivers a single application through the browser to thousands of customers using a multitenant architecture. On the customer side, it means no upfront investment in servers or software licensing; on the provider side, with just one app to maintain, costs are low compared to conventional hosting. SaaS is offered in the form of enterprise applications, HR apps and has even worked its way up the food chain to Enterprise Resource Planning (ERP).
