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 maintaining software, you simply access it through the Internet, freeing your self from advanced software and hardware management.

SaaS applications are sometimes called Web-based mostly software, on-demand software, or hosted software. Regardless of 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
An excellent way to understand the SaaS model is by thinking of a bank, which protects the privacy of each buyer while providing service that is reliable and safe—on an enormous scale. A bank’s prospects all use the identical financial systems and technology without worrying about anyone accessing their personal information without authorisation.

A "bank" meets the key characteristics of the SaaS model:

Multitenant Architecture
A multitenant architecture, in which all users and applications share a single, widespread infrastructure and code base that is centrally maintained. Because SaaS vendor shoppers 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can innovate more quickly and save the valuable development time previously spent on maintaining numerous versions of outdated code.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 each consumer to easily customise applications to fit their business processes without affecting the frequent infrastructure. Because of the way SaaS is architected, these customisations are distinctive to each firm or user and are always preserved by upgrades. That means SaaS providers can make upgrades more typically, with less customer loyalty risk and far lower adoption cost.
Higher Access
Improved access to data from any networked device while making it easier to manage privileges, monitor data use, and guarantee everyone sees the same information on the similar time.
SaaS Harnesses the Consumer Web
Anyone acquainted with Amazon.com or My Yahoo! will be acquainted with the Web interface of typical SaaS applications. With the SaaS model, you can customise with point-and-click ease, making the weeks or months it takes to replace traditional enterprise software seem hopelessly old fashioned.
SaaS Developments

The consulting firm Saugatuck Technology calls this the "third wave" in software adoption: when SaaS moves past standalone software functionality to grow to be a platform for mission-critical applications.

SaaS v packaged software

Using packaged software placed a burden on the IT crew which could turn right into a bottleneck for projects.
A business may end up needing to help a wide variety of systems side by side, but discover it tricky to integrate them as they had been coded and built differently.
This approach additionally introduced upfront costs for software and licences and doubtlessly servers for the software to sit on.
