SaaS, PaaS and IaaS: Understanding the Differences
In the world of cloud computing, it’s easy to get confused by all the acronyms and buzzwords thrown around. One of the most commonly used terms is the “SaaS, PaaS, and IaaS” combo. These three acronyms are often used interchangeably, but they refer to different services. In this post, we’ll break down what each of these terms means, and how they differ.
As a business owner, you’re likely well-versed in the various cloud computing services available to you. However, it can be challenging to understand the distinctions between SaaS, PaaS, and IaaS. We’ll try to break down the differences between these services through real-world examples, so you can make an informed decision about which one(s) your business needs.

SaaS: Software as a Service
“SaaS removes the need for businesses to install and run applications on their own computers or in their own data centers. This can result in significant cost savings.” — Marc Benioff, CEO of Salesforce.
SaaS, or Software as a Service. This type of cloud computing service delivers software applications over the internet on a subscription basis. SaaS allows you to access your software remotely, which means you don’t have to worry about installation or maintenance. Consider the example of a small business owner, who used to spend hours managing customer relationships using excel sheets and email. By subscribing to a SaaS-based CRM system, the business was able to automate many tasks and streamline its customer interactions. Examples of SaaS include web-based email services, customer relationship management (CRM) systems, and online office suites.

PaaS: Platform as a Service
“PaaS is a way of providing a platform for developing and deploying applications, without having to worry about the underlying infrastructure. This allows developers to focus on what they do best — writing code.” — Bill Gates, former CEO of Microsoft.
Next up is PaaS, or Platform as a Service. This type of service provides a platform for developing and deploying applications. Imagine a start-up company that was working on a new application. With PaaS, the company was able to access the servers, storage, and networking needed to run the application, as well as development tools, databases, and other services, without having to worry about managing the underlying infrastructure. They were able to focus on building and deploying their application and bringing it to market faster. Examples of PaaS include Heroku, AWS Elastic Beanstalk, and Google App Engine.
IaaS: Infrastructure as a Service
“IaaS makes it possible for businesses to rent computing resources on demand, rather than having to invest in their own hardware. This can help companies to scale their infrastructure up or down as needed, and only pay for what they use.” — Larry Ellison, co-founder of Oracle.
Finally, there’s IaaS, or Infrastructure as a Service. This service allows users to rent computing resources on demand, such as servers, storage, and networking. A large e-commerce company, for example, may experience a huge spike in traffic during the holiday season. Rather than investing in expensive hardware to handle the increased traffic, the company can use IaaS to scale its infrastructure up or down as needed and only pay for what they use. This means they can handle a surge in traffic without overspending on infrastructure they may not need for the rest of the year.
Examples of IaaS include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.
In summary, SaaS, PaaS, and IaaS are all different types of cloud computing services that can be used to meet different needs. SaaS is a way to deliver software applications over the internet, PaaS is a platform for developing and deploying applications, and IaaS is a way to rent computing resources on demand. Understanding the differences between these services can help you make better decisions about which one(s) your business needs.
“The cloud is the most important innovation in enterprise IT since the mainframe, and SaaS is the most important aspect of the cloud.” — Matt Holleran, Managing Director at Amplify Partners.
