What is SaaS Software?

Software as a service(SaaS) is a software distributing model where the third party provider hosts application and make them available for a customer over the internet. Saas is the category of cloud computing. There are three main categories in cloud computing is Software as a service(Saas), infrastructure as a service(IaaS), Platform as a service(PaaS). SaaS is closely related to an application service provider(ASP).

 Nice explanation. SaaS has become very popular because users don’t need to install or maintain software—everything is managed by the provider and accessed online. The SaaS vs PaaS comparison is also interesting since SaaS provides ready-to-use applications, while PaaS focuses more on development platforms. I’ve also seen some useful insights about these cloud models shared on FHSEOHUB.
