What’s SaaS?

Software as a service (or SaaS) is a way of delivering applications over the Internet—as a service. Instead of installing and sustaining software, you merely access it by way of the Internet, freeing yourself from advanced software and hardware management.

SaaS applications are sometimes called Web-based software, on-demand software, or hosted software. Whatever the name, SaaS applications run on a SaaS provider’s servers. The provider manages access to the application, together with security, availability, and performance.

SaaS Characteristics

A very good way to understand the SaaS model is by thinking of a bank, which protects the privateness of every customer while providing service that’s reliable and secure—on a massive scale. A bank’s customers all use the identical financial systems and technology without worrying about anybody accessing their personal information without authorisation.

A «bank» meets the key traits of the SaaS model:

Multitenant Architecture

A multitenant architecture, in which all users and applications share a single, widespread infrastructure and code base that’s centrally maintained. Because SaaS vendor purchasers are all on the identical infrastructure and code base, vendors can innovate more quickly and save the valuable development time previously spent on maintaining numerous versions of outdated code.

Easy Customisation

The ability for every consumer to easily customise applications to fit their enterprise processes without affecting the common infrastructure. Because of the way SaaS is architected, these customisations are distinctive to every firm or user and are always preserved through upgrades. Meaning SaaS providers can make upgrades more typically, with less customer risk and much lower adoption cost.

Better Access

Improved access to data from any networked gadget while making it simpler to manage privileges, monitor data use, and guarantee everybody sees the identical information at the similar time.

SaaS Harnesses the Consumer Web

Anybody familiar with Amazon.com or My Yahoo! will be acquainted with the Web interface of typical SaaS applications. With the SaaS model, you’ll be able to customise with point-and-click ease, making the weeks or months it takes to replace traditional enterprise software seem hopelessly old fashioned.

Organisations at the moment are creating SaaS integration platforms (or SIPs) for building additional SaaS applications. The consulting firm Saugatuck Technology calls this the «third wave» in software adoption: when SaaS moves beyond standalone software functionality to turn into a platform for mission-critical applications.
