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 maintaining software, you merely access it via the Internet, liberating yourself from complex 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, including 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 each customer while providing service that’s reliable and secure—on a large scale. A bank’s customers all use the same 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, common infrastructure and code base that’s centrally maintained. Because SaaS vendor purchasers are all on the same infrastructure and code base, distributors can innovate more quickly and save the valuable development time beforehand spent on maintaining numerous versions of outdated code.

Easy Customisation

The ability for every user to simply customise applications to fit their business processes without affecting the widespread infrastructure. Because of the way SaaS is architected, these customisations are distinctive to every company or consumer 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 easier to manage privileges, monitor data use, and ensure everyone sees the same information on the same time.

SaaS Harnesses the Consumer Web

Anyone familiar with Amazon.com or My Yahoo! will be familiar with the Web interface of typical SaaS applications. With the SaaS model, you possibly can customise with level-and-click ease, making the weeks or months it takes to replace traditional business software appear hopelessly old fashioned.

SaaS Trends

Organisations are actually developing 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 past standalone software functionality to change into a platform for mission-critical applications.

SaaS is one in every of several cloud computing solutions for business IT issues. Other ‘as-a-Service’ options include:

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

Platform as a Service (PaaS)

Everything as a service (XaaS) – which is essentially all of the «aaS» tools neatly packaged together.

The payment model for these kinds of services is typically a per-seat, per-month cost based mostly on utilization – so a enterprise only has to pay for what they need, reducing upfront costs.

SaaS v packaged software

In the past, businesses purchased and relied on packaged software – from multi-application systems covering spreadsheets, databases and e-mail to specialist packages for particular tasks like project management or enterprise intelligence.

Packaged software – the drawbacks

To use sales and marketing for example, a enterprise could have used on-premises software for CRM.

This software wanted to be evaluated, purchased, put in, kept safe, maintained and usually upgraded on in-house systems by the interior IT department.

Using packaged software positioned a burden on the IT group which may turn into a bottleneck for projects.

A enterprise might find yourself needing to support a wide variety of systems side by side, but find it tricky to integrate them as they had been coded and built differently.

This approach additionally presented upfront costs for software and licences and probably servers for the software to sit on.

The prices of the CRM software and hardware would possibly mean it is not affordable for small businesses. It could also be difficult to scale up quickly in response to development or change.
