PaaS and IaaS are two of the earliest and most widely used cloud computing services. They are similar in some ways, yet fundamentally different types of platforms. In simple words, IaaS is the combination of PaaS, Operating System, Middleware, and Runtime.

Enterprises must understand these differences to choose the right type of cloud service for a given use case. Infrastructure-as-a-Service (IaaS) offers added control and flexibility over cloud infrastructure but is more complex to manage and optimize. In contrast, Platform-as-a-Service (PaaS) solutions offer the tools and the infrastructure required to expedite deployment. 

However, security, integration, and vendor lock-in are issues to look at in PaaS. This blog explains the definitions of IaaS vs. PaaS, its benefits and drawbacks, and a few examples of both IaaS and PaaS.

IaaS vs. PaaS– Definitions

Infrastructure as a Service (IaaS) offers on-demand access to virtualized IT infrastructure through the internet. Mostly, IaaS offerings allow access only to the core infrastructure components like compute, networking and storage. Users can install and manage the software they want to run on their cloud-based infrastructure.

Platform as a service (PaaS) offers the infrastructure to host applications and also software tools to help clients build and deploy the applications. PaaS simplifies the entire setup and management of both hardware and software.

Comparatively, PaaS is less flexible than IaaS and mainly caters to a narrow set of application development or deployment approaches. To be honest, they are not general-purpose replacements for an enterprise’s complete IT infrastructure and software development workflow.

IaaS vs. PaaS- Benefits

Infrastructure-as-a-Service solutions offer networking, storage, servers, operating systems, and other resources required to run the workloads. Infrastructure is made available by making use of the virtualization technology and can be used on a pay-as-you-go model.

Benefits of IaaS solutions are:

Platform-as-a-Service solutions offer cloud-based environments for developing, testing, running, and managing web-driven and cloud-driven applications. Companies get a state-of-the-art development environment without the need to buy, build or manage the underlying infrastructure. 

Benefits of PaaS solutions are:

IaaS vs. PaaS- Disadvantages

Disadvantages of IaaS are:

Disadvantages of PaaS are:

IaaS vs. PaaS- Examples

Examples of IaaS are:

AWS- Amazon Web Services

Microsoft Azure

Google Cloud

Digital Ocean

Alibaba Cloud

Examples of PaaS are:


Elastic Beanstalk from AWS

Engine Yard

Open Shift from RedHat


IaaS and PaaS are the most impressive emerging technologies ruling the world of cloud computing currently. Both have their own benefits and disadvantages. However, understanding the details given above can help identify which of these services will be beneficial for you to use. The choice depends on the requirements of specific workloads. 

To keep up with the emerging standards of modernization, enterprises must invest in cloud computing. Not only will it help in serving your customers better, but it will also help your business grow. It will remove the complexities and limitations that traditional IT infrastructures pose. Once you’ve decided that, choose whether you must opt for IaaS or PaaS, depending on how you want to run your cloud-based applications.
