SaaS, IaaS, and PaaS – What Is The Difference? Iaas, Paas & Saas

The advancement of technology and the use of the internet have completely changed the way people interact, consume content, and have fun. However, this change also extends to the business world, improving money savings and agility in solving problems.

In offices all over the world, professionals use outsourced systems in their daily lives, which include everything from video editing programs to CRMs, internal communication, and much more.

With most of these services, the companies that use them don’t necessarily buy them once to install them on certain devices. This would limit access for employers.

Instead, the software required to run the business is accessed remotely via a login and password and can be accessed from any device with an internet connection.

This software access (services, products, and infrastructure) is classified as SaaS, IaaS, and PaaS, and can be accessed through Cloud Computing.

All of these acronyms may sound confusing at first, but stay with me to learn what they all mean and how these concepts are more common in your day-to-day life than you might think.

Before I explain SaaS, IaaS, and PaaS, let me first explain Cloud Computing, which is the technology at the heart of everything.

What Is Cloud Computing?

Cloud computing is a method of hosting and distributing software over the internet. This technology assumes that the user (individual or company) does not require the system itself, but rather the benefits it provides.

The user can access various software through Cloud Computing, and all they need is a device with internet access, eliminating the need to download or install programs that are only available on one device.

The main advantages are cost savings for the user, who only pays for what he needs, and agility, because all access is done remotely.

Cloud computing is responsible for the existence of concepts such as SaaS, IaaS, and PaaS, which are the focus of this article. But what are these terms, and how do they affect people’s and businesses’ daily lives?


Quoting our own article: Software as a Service (SaaS) is a software distribution model in which a cloud provider hosts features and delivers them over the internet as a service.

There are many famous companies using the SaaS model, and a great example is Netflix.

Thinking about Netflix is a great way to understand SaaS. You don’t have to pay a high price for physical media when you want to watch a movie because you already pay a monthly fee for your account, which grants you access to their entire catalog.

It is very common for SaaS companies to charge for services with monthly fees or annual packages, which allows them to offer their software to a large number of users at a low cost.

Here are some examples of companies that use SaaS as a business model:


Infrastructure as a Service (IaaS) is when a user contracts infrastructure services remotely rather than purchasing hardware. Memory, storage, routers, and servers are a few examples.

Infrastructure as a Service (IaaS)

In the IaaS model, the user has access to the infrastructure without incurring high costs for expensive devices such as servers.

One of the most significant advantages is that you can customize the hiring of infrastructure to your monthly requirements. With this model, you can hire a server capacity that can be increased as needed, in an agile and remote manner.

Platform as a Service (PaaS) refers to the hiring of a platform to create, modify, and optimize software and applications. Instead of investing in in-house resources, simply hire this service and your IT team will have access to a fully functional internet-based environment.

A major benefit of this model is the customization of features. Your development team has access to a complete environment, which allows them to add or modify features according to their needs.

Furthermore, because it is remote access, your developers can work from home without interfering with access to necessary resources.

Understanding these models is critical to knowing exactly what your business requires, saving money, and reducing implementation time.

Hopefully, you are now better acquainted with the different models and which would work best for you as a user or as part of your business solution.
