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, releasing your self from complicated software and hardware management.

SaaS applications are typically 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 great way to understand the SaaS model is by thinking of a bank, which protects the privacy of every buyer while providing service that's reliable and secure—on a massive scale. A bank’s prospects all use the identical monetary systems and technology without worrying about anyone accessing their personal information without authorisation.

A "bank" meets the key traits 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 clients are all on the same infrastructure and code base, vendors can innovate more quickly and save the valuable development time beforehand spent on maintaining quite a few versions of outdated code.

Easy Customisation

The ability for every person to easily customise applications to fit their business processes without affecting the common infrastructure. Because of the way SaaS is architected, these customisations are distinctive to every firm or consumer and are always preserved by means of upgrades. Which means SaaS providers can make upgrades more usually, with less buyer risk and much lower adoption cost.

Higher Access

Improved access to data from any networked machine while making it simpler to manage privileges, monitor data use, and guarantee everyone sees the same information on the similar 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'll be able to customise with level-and-click ease, making the weeks or months it takes to replace traditional business software appear hopelessly old fashioned.

SaaS Developments

Organisations are now 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 beyond standalone software functionality to grow to be a platform for mission-critical applications.

SaaS is considered one of a number of cloud computing options for business IT issues. Other ‘as-a-Service’ options embrace:

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

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 providers is typically a per-seat, per-month cost based on usage – so a business only has to pay for what they want, reducing upfront costs.

SaaS v packaged software

Prior to now, companies bought and relied on packaged software – from multi-application systems covering spreadsheets, databases and electronic mail to specialist packages for particular tasks like project management or enterprise intelligence.

Packaged software – the drawbacks

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

This software wanted to be evaluated, bought, installed, kept safe, maintained and repeatedly upgraded on in-house systems by the internal IT department.

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

A business might find yourself needing to help a wide variety of systems side by side, but find it tricky to integrate them as they have been coded and constructed differently.

This approach also presented upfront prices for software and licences and potentially servers for the software to sit on.

The prices of the CRM software and hardware may mean it will not be affordable for small businesses. It could also be troublesome to scale up quickly in response to growth or change.
