What’s SaaS?
Software as a service (or SaaS) is a way of delivering applications over the Internet—as a service. Instead of putting in and sustaining software, you simply access it by way of the Internet, freeing yourself from complex software and hardware management.
SaaS applications are generally called Web-primarily based 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
A good way to understand the SaaS model is by thinking of a bank, which protects the privacy of every customer while providing service that’s reliable and secure—on a large scale. A bank’s customers all use the identical monetary 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 customers and applications share a single, widespread infrastructure and code base that’s centrally maintained. Because SaaS vendor shoppers are all on the same infrastructure and code base, distributors can innovate more quickly and save the valuable development time previously spent on maintaining numerous versions of outdated code.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 enterprise processes without affecting the widespread infrastructure. Because of the way SaaS is architected, these customisations are unique to every company or person and are always preserved through upgrades. Meaning SaaS providers can make upgrades more usually, with less customer risk and far lower adoption cost.
Higher Access
Improved access to data from any networked system while making it simpler to manage privileges, monitor data use, and ensure 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 possibly can customise with point-and-click ease, making the weeks or months it takes to update traditional enterprise software appear hopelessly old fashioned.
SaaS Traits
Organisations are now growing SaaS integration platforms (or SIPs) for building additional SaaS applications.

Infrastructure as a Service (IaaS) – the provider hosts hardware, software, storage and other infrastructure part

Everything as a service (XaaS) – which is essentially all of the “aaS” tools neatly packaged together.
The payment model for these kinds of companies is typically a per-seat, per-month charge based on usage – so a enterprise only has to pay for what they need, reducing upfront costs.
SaaS v packaged software

A business might end up needing to support a wide number of systems side by side, but find it tricky to integrate them as they were coded and constructed differently.
This approach additionally introduced upfront costs for software and licences and doubtlessly servers for the software to sit on.
