PaaS vs. IaaS: What's The Difference?

Perhaps you've heard your IT team take on a PaaS vs. IaaS debate lately, and you're still mystified over what these acronyms mean. If you're new to cloud services, you're probably still trying to understand many of the "as a service" options cloud providers give you. PaaS and IaaS are two of the most popular, though you also have SaaS (Software as a Service), and many others placing your business tools in the cloud.

PaaS vs. IaaS: What's The Difference?PaaS stands for "Platform as a Service" and gives you a platform for developing software delivered through the web. You could say it's similar to SaaS, except the key difference is that PaaS isn't simply providing web-based software.

IaaS stands for "Infrastructure as a Service", and it has some similarities to PaaS. However, it's more comprehensive in giving you business tools specific to your applications.

Still, you're perhaps a little confused over the real difference between these two. Let's look more in detail at what features each brings to show you reliable comparisons.

The Real Benefits to PaaS

If you've grown frustrated recently at having to constantly manage your operating systems, PaaS eliminates this by not being reliant on upgrades or versioning on your server. For your software development team, this makes deploying code less likely to fail because of OS versions not matching and makes continuous delivery more achievable.

Anything related to infrastructure for development becomes available through the cloud for access at any time.

But the characteristics of PaaS go beyond the above generalities. With varying services and other features, you can do things to help bring better integration and collaboration.

What Characteristics in PaaS Stand Out?

One aspect you'll appreciate is your demand for resources has scalability whenever it's needed in your company. When you experience a sudden influx of growth, you don't have to invest your own capital into expanding your servers to keep up with demands. PaaS lets you scale up or down instantly for what you need while having your cloud provider give you needed updates.

As for other services, it gives you everything you need for application management, software testing, deployment, and hosting without having any physcial infrastructure.

Since you're using the cloud, you have universal access to these features, meaning multiple employees can access your development application. During times when your team is out of the office, they can still work through the cloud platform using a mobile device.

The Benefits of IaaS

If you're a startup, investing in infrastructure may become a major budgetary constraint that IaaS fixes. It provides all the IT infrastructure you need to run a business without having to build a physical data center.

The cost of IaaS varies depending on how much infrastructure you need, effectivley avoiding unneccesary spending on server power.  It is also very scalable, which means you can easily expand as you needs increase.

As a growing organization, you may not want to commit to hardware and software investments right away until testing what you need. IaaS allows you to do this at a reasonable price and scale appropriatley to your organizations needs as they change.

So What's the Difference Between PaaS and IaaS?

The real difference is IaaS gives you more to manage than with a PaaS. More precisely, your applications, data, middlewear, OS versions, and security are all managed by you through IaaS. Through PaaS, you only manage your applications, while security and your database get controlled by the hosting vendor.  It eases the burden on developers, and make deployments a breeze.

What they have in common is the reliable management by your provider for the virtualization, servers, storage, networking, and data centers as a whole.
