IaaS vs PaaS


Cloud computing is everywhere now, and there is a need for adapting to it because as the requirements are going high side by side with technology. It is becoming very tough for an on-premises software/environment to satisfy those needs, so to ease up things cloud computing came into the picture. Cloud Computing’s motive is to provide scalable resources online either on-demand or pay-as-you-go model it depends upon your needs. What makes a cloud-like one of the most significant players in the market is its scalability towards the resources and also the network access associated with it. Cloud computing has its services to carry out the tasks, and these tasks include giving out the executable environment, software, servers, etc. These tasks more broadly could be labelled as needs from the user or the client-side, which is not able to host so much of resources from its side. These services have their names, norms, and regulations which if put together is capable of covering up all the requirements of the client-side. Namely, we have three types of services available which are SaaS, i.e. software as a service, PaaS, i.e. platform as a service, IaaS, i.e. Infrastructure as a service they all collectively are instrumental. I bet you have already heard about them at some point in your professional life. Today our primary focus is on putting light on PaaS, i.e. platform as a service and IaaS, i.e. Infrastructure as a service. So let’s get started.

Platform as a Service

What is Platform as a Service? 

Platform as a service provides the programming executable run-time environment, data storage, servers, networking sector or in-short covers up 80% of your resource requirements which if decided to take it on-premise would cost a lot. It supports the complete life cycle of building and delivering web applications. What is happening is, the service provider sorts all the needs except application and data. 

One trendy thing which is very much around the platform as a service which is booming the market and that is CPaaS, i.e. Communication Platform as a service which allows users to add communication capabilities like videos, audio, etc. in your application or your product. This also allows the user to add new features like notifications, pop-ups, etc. which help to increase the interaction between the client and the supplier. 

What is the need for Platform as a Service?

If you think/see the current trend in technology, you cannot ignore the positive effects of the cloud in the current technology sector. If you take the case of Paas it is providing the environment for you to build, develop and run your web application which was a huge task a few years back but Paas completely revolutionized it. And the definition is sufficient to explain why. 

Infrastructure as a Service

IaaS, PaaS, and SaaS they all come under all cloud paradigm whose whole motive is to provide on-demand network access to the shared computing resources, which is very costly if chosen individually. It is getting offered to the clients/user where billing is very flexible, which users can optimize based on their needs. Infrastructure as a service plays a crucial part in the cloud as it is providing the computer architecture for you to add your middleware, operating system, application, data, etc. as per your needs. It is offering data storage, virtualization, servers, and networking to the user while all other is getting added by the user. It is in-short, giving you an ideal environment to build, For example, you rented a house, and it was delivered to you in a semi-furnished manner, so make your home look happening, you will start adding your things. I hope this example gave you some idea what Infrastructure is providing you.

What is the need for Infrastructure as a Service?

The popularity of Infrastructure as a service is high in the market, and there are so many examples of IaaS around you. I am not pointing that they all are only working on the IaaS no, they do have their own PaaS and SaaS as per their needs. But IaaS play a role of the base for building an architecture of entity be it a software, product or web application.

Benefits of IaaS and PaaS

Benefits of IaaS

  • Infrastructure 

It may sound straightforward that Infrastructure is getting provided. Still, the reality is, the cost-cutting you would be achieving after IaaS is high if you compare it to the simple on-premise services.

  • Scalability

The scalability associated with the IaaS is very hard to ignore its sheer size could be stretched as per your needs.

  • Time to Market

In the end, time to market is the only thing left to point whether you have achieved something through your entity or not. And as we all know, every minute passing is very crucial in the industrial market so even the slightest delay could cause you massive damage. So for that Infrastructure is providing you the less time to market so that you can deploy your application on time without any delay.

Benefits of PaaS

  • Rapid Development

The thing rapid development is very much crucial if you want your product/application to be built at a fast pace. The rapid growth associated with PaaS is the most significant advantage why most of the tech-giants opt for PaaS while building their application. Everything required is available already so instead of spending time on setting-up with middleware and operating system, you could work on your data and the development of your application.

  • Cost-Effective

While every cloud service if cost-effective in their way. So if you talk about PaaS cost-effectiveness, then you could easily take an idea from the resources you are getting and using them to develop and run your application. Supplies used are very costly if counted and priced as an individual entity.

Challenges of IaaS and PaaS

Challenges of Infrastructure as a Service

  • Internet

The Internet plays a crucial part while you are working on the cloud if you don’t have a proper fluent internet connection, then you may face problems in your cloud user environment while working. No one wants any hindrance in there as it might cause a delay in your project delivery cycle.

So, one biggest flaw in all the services is its Infrastructure, platform, etc. is somewhat associated with the internet connection.

  • Data Security

As Infrastructure follows a multi-tenant architecture than you might face some security issues as well. As having multi-tenancy, your work could easily get affected by the configurations of others if not paid proper attention.

The main crux is Infrastructure as a Service is suitable for small projects where demands keep on changing but if you put IaaS in the massive project than you could face problems as you will find yours in a situation where it would be becoming very hard to keep up with the modifications and changes that are going on and those changes that need to be done shortly. 

And even sometimes it would be hard to gather the resources from the vendor in the times when the vendor will not be able to fulfil your demands because of some concerning reasons. In this, you will feel sometimes restricted towards the customization, so you better be looking or having a proper approach.

Challenges of Platform as a Service

  • Internet

Internet here is a crucial issue which we have already covered in the challenges of IaaS.

  • Compatibility

Not every Infrastructure on the platform is residing is compatible with the configuration which the user wants. So, this creates a massive issue while you will be having a chunk of other handy resources. Still, because of compatibility issues, they end up going in vain, which not only wasting the important of yours but your efficient resources.

  • Dependency

Just like the Internet is sometimes creating problems the addictions associated with cloud from the vendor side is creating a massive problem in the cloud services available which are limiting the software to give their best or more broadly you will not be getting that efficient product in the end.


To succeed in the area of cloud services you need to attain that speed, you to earn that reliability and you have to have that support to have a proper vision and a team to give you a back when something goes wrong. When we ta about working with PaaS, you have to have those skills nurtured and efficient to achieve something; otherwise, you will get affected and because you the whole company might also get affected.

 It is no good and evil in the cloud it depends upon the need of the enterprise and the environment the enterprise is working or wants to work, and if all goes well, then there will be no stopping back.
