SaaS, or \u201cSoftware as a service,\u201d is a kind of software model where a service provider hosts applications virtually on the cloud and distributes them to end-users and other business counterparts through the internet. For example, the individual software vendor (ISV) may reach out to a separate cloud provider entity to host the particular application or set of applications. Moreover, for larger companies, the software vendor itself is the cloud provider hosting applications on the internet.<\/p>\n\n\n\n
SaaS is one of three main categories of cloud computing. The other two are Infrastructure as a service (IaaS) and Platform as a service (PaaS). SaaS products are now completely mainstream, having a user community that ranges from corporate IT professionals, professional business users, and personal users of all age groups. In addition, the cloud-based distribution model contributes to more than 60% of web-based products than on-premise Software.<\/p>\n\n\n\n
