The Differences between IaaS, SaaS, and PaaS

Cloud | | Industry Thoughts

IaaS, SaaS, and PaaS are all cloud computing solutions. When you need to create an app for your business you have a couple different options, so it’s important to understand the differences between IaaS, SaaS and PaaS. You can either build something yourself, use something that’s already built, or build something off of something someone has already started.

IaaS (Infrastructure-as-a-service)

This is the most basic of the three. The service provider has created the infrastructure, and that’s it. This allows the developer to create their own platform and software. The responsibility of maintaining and updating the system falls on the developer and not the provider. This service provides more flexibility and requires a higher amount of technical knowledge… or at least knowing someone who does.

SaaS (Software-as-a-service)

SaaS comes with infrastructure, the platform and even the software.

Depending on the SaaS’s purpose, it could include e-commerce, enterprise or other types of software already installed on the platform. SaaS are for businesses who don’t want to deal with the maintaining or creating the software for their applications.

SaaS doesn’t offer the flexibility of creating custom software like IaaS, but instead offers more generic software for consumers.

PaaS (Platform-as-a-service)

We’ve written a brief overview of PaaS before, so check that out too.

PaaS is going to offer you the hardware and the infrastructure for running applications over the internet. The service provider has already built the infrastructure and the platform, so all the developer has to do is write their program and deploy it. Boom. That was simple. Maintenance falls on the PaaS provider; so that’s one less thing the developer has to worry about.

But for a lot of people, that’s just a lot of words. So, here’s a chart to help show the differences between IaaS, SaaS and PaaS and where responsibilities lie. (Thanks to the CIO Research Center for this awesome graphic).
