SaaS, PaaS, IaaS — which of these cloud service models should you use?
We’ll explain the differences so you have a better understanding.
Cloud service models come in three types:
- IaaS (Infrastructure as a Service)
- PaaS (Platform as a Service)
- SaaS (Software as a Service)
Each of these cloud service models have their own set of benefits that could serve the needs of your organisation.
The type you choose will depend on how you use it — whether for hosting (IaaS), building (PaaS) or consuming (SaaS).
If you're slightly confused, don't worry.
We'll take an in-depth look at each of the cloud service models mentioned above.
If you do anything that requires the raw computing power of data centers, you'd use IaaS.
Basically, IaaS providers enable you to consume the computing power of physical data centers through the Internet.
In short, IaaS providers put infrastructure components such as networking, storage, server and virtualization online to be consumed.
Mostly, these infrastructure components are made available by third-party providers such as Microsoft Azure or Amazon Web Services (AWS).
As IaaS allows you to host services online without possessing any hardware, managing physical infrastructure in-house might soon become a thing of the past.
When IaaS is for hosting, PaaS is for building.
When your organisation is developing software, the solution it needs is PaaS.
In addition to networking, storage, server and virtualization, PaaS providers also take care of the O/S, middleware and runtime.
This makes PaaS the perfect canvas for all your development needs – regardless how big or small.
With a near endless ability to build and destroy, PaaS will definitely supercharge any variety of projects you might have.
If IaaS is for hosting, and PaaS is for developing, then SaaS is for consuming.
When using software in the past, you may have had to first install it on your device with a tangible CD or by means of a downloaded code.
Today, most software is delivered as SaaS over the Internet and consumed in a browser.
SaaS solutions come in all shapes and sizes.
But what they all have in common is that they can be consumed through a monthly subscription.
This also means that service providers manage the entire IT stack when it comes to SaaS, from the network to the applications.
Consequently, you won’t be able to host or build IT.
But SaaS allows you to lean back and simply consume IT – at your leisure.
By now you hopefully have a better idea about the bigger picture when it comes to cloud service models.
But what are the practical applications when it comes to IaaS, PaaS and SaaS?
Let’s look at the modern workplace to find out!
When you think about how we work today, you’ll quickly realise that we all need some basic things to be productive: a laptop, Internet, an O/S and, you guessed it, applications!
Joe Public might argue that equipping your employees with the software they need is the easiest thing to do.
Far from it!
How do you host it (IaaS), how do you build it (PaaS) and how should it be consumed (SaaS)?
The options are endless.
This is where AHP comes into play.
AHP is an orchestration platform that allows IT administrators to manage and control IT ecosystems, and users to work productively in a self-defined manner.
The trick is that all of this can be done through a single pane of glass!
Basically, this allows you to run and consume any app, on any desktop, from any infrastructure.
Cloud service models come in three types: IaaS (Infrastructure as a Service), PaaS (Platform as a Service) and SaaS (Software as a Service).
And the great thing about them is that they're scalable, giving you the ability to grow – minus the hassle.
The easiest way of doing so is by means of a single pane of glass.
