Understanding Software as a Service (SaaS)
FAQs
Software as a service (SaaS) is a software distribution model where SaaS service providers offer access to cloud-hosted applications on a subscription basis.
Many SaaS providers host their applications in the cloud and then sell users the right to use that application via a subscription service. The user doesn't need to install the software on their PC or mobile device and no additional infrastructure, other than an internet connection, is required to access it.
SaaS applications use the SaaS delivery model where users are actually purchasing access to a single software application that has been optimized for SaaS. This means that users are purchasing access rights vs. software ownership. In addition, since there is one application being accessed by all users, there is little flexibility in terms of modification requests other than branding look and feel.
Some key elements of SaaS architecture include:
* Single sign-on.
* Multi-tenancy.
* Scalable, elastic infrastructure.
* Automated provisioning.
* API-driven access management.
