SaaS, PaaS and IaaS- Major Differences Between the 3 Cloud Topics

‍In the software world, new acronyms are popping up faster than new internet-based businesses. The growth of cloud computing has led to a proliferation of new cloud computing acronyms and their meanings. What is even more confusing is that these terms are used interchangeably, often with no explanation as to what they mean or how they differ from one another.

If you are not exactly sure what the differences are between Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) or whether you should use them in your business, read on. This blog post will explain everything you need to know about these terms, so you can choose which one(s) might be right for your business.

What is SaaS?

SaaS stands for Software as a Service and refers to a software model that provides software applications to customers via the internet. While SaaS can be any type of software, it is most frequently used to describe business software, like Salesforce or Microsoft Office 365.

Saas allows users to access software applications through the Internet or mobile devices without having to install or maintain the software themselves. Saas providers typically charge monthly fees for their services, which can be broken down into per-user, per-month and per-seat fees. It is like renting space in someone else’s building; you don’t have to worry about maintaining it or paying for equipment. You just pay for their services and get what you need when you need it.

What is PaaS?

Platform as a Service (Paas) is software that allows users to develop applications on top of an operating system (such as Linux) or other tools (such as an app store). This means that developers can create applications without having to learn how these platforms work first. They simply write code and upload it to the platform where it runs without any further configuration required by the user.

Unlike Saas where developers are responsible for maintaining the application code, Paas providers offer maintenance and support services so developers don’t have to worry about it. Paas providers typically charge monthly fees for their services, which can be broken down into per-user, per-month and per-seat fees

What is IaaS?

IaaS stands for Infrastructure as a Service and refers to a service that provides hardware resources like servers, storage and networks. IaaS can be useful if your business wants to use a specific hardware setup, or if it needs to support a large number of users at once, but doesn’t want to purchase hardware. IaaS is commonly used when businesses want complete control over the hardware being used for example, if your company has very specific hardware requirements or needs to support a large number of users at once.

Final Words

Saas, Paas, and IaaS are different types of software delivery models. While Saas is the most common model for new businesses, Paas and Iaas are common models for established businesses.
