Paas vs Iaas vs Saas: Decoding Various Cloud Computing Service Models

Posted By : Anmol Kalra | 19-Oct-2021


The world is swiftly evolving to adapt to the growing changes that businesses put forward and experiencing unprecedented strain on maintaining a cost-effective and robust IT Infrastructure. But thanks to Cloud Computing and its multiple service models – PaaS, SaaS, and IaaS firms now have the alternative to move beyond on-premise IT Infrastructure for advanced processing and storage capacity. They have come to rely on various IT platforms, and software offered as a service. 


The future of computing is set in the clouds! Missing out on it can curb down the progress and performance capabilities of a company. But before we go deeper in decoding cloud computing seamlessly, let’s shed some light on cloud computing?

What is Cloud Computing?

In a nutshell, cloud computing means computing using the Internet as a medium to deliver services and resources.

While traditional computing requires you to use programs, store data, or retrieve files with hardware or components connected to a primary computer. Cloud computing empowers computers to benefit from shared resources and databases of computers connected to a single network.


Basically, every computation occurs using the Internet or the cloud. Still, Cloud computing is beneficial since we can store all our data on remote databases instead of being limited to storage devices or local hard drives. This extends to single files as well as complex programs or software.

Many people and firms look up to cloud computing due to its efficiency and cost savings methodology.


When it comes to relocating your business to the cloud, you encounter three basic types of cloud computing services: Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS).

And in this blog, we'll help you decode these three key cloud computing models, which will eventually help you find the suitable tech configuration for your business.


Types of Cloud Computing

Cloud computing comes in a wide diversity, depending on the needs of the business and the goal of the cloud provider. Cloud services can be deployed using three ways: public, private, and hybrid cloud


  • Public cloud: A cloud environment created from resources not maintained by the end-user, which can be redistributed to other occupants. e.g., Microsoft Azure, Amazon Web Services, and Google Cloud.
  • Private cloud: Refers to cloud computing resources that are used solely by a single business. A private cloud can be located physically on the company's on-site data center.
  • Hybrid cloud: Hybrid clouds have the functionality of both. It combines both public and private clouds. 


PaaS, SaaS, and IaaS stand for Platform-as-a-Service, Software-as-a-Service, and Infrastructure-as-a-Service, respectively. Each describes different methods of how you can benefit from the cloud for your organization. 


While conventional computing solutions require managing your own IT infrastructure and in-house software service, IaaS provides pay-as-you-go storage, networking, and virtualization approaches. In addition, PaaS includes even more benefits like hardware and software development tools available via the web. And with SaaS, you get the most significant degree of vendor management by “renting” complete software solutions.

Infrastructure as a Service (IaaS)


It provides a virtual stock of computing resources over the cloud. An entire range of computing infrastructures such as storage, servers, networking hardware alongside maintenance and support can be borrowed by IaaS cloud provider service. IaaS is a highly scalable solution and offers businesses more flexibility than other on-premise solutions.


Businesses and firms can opt for computing resources of their requirement without installing hardware on their premises. Microsoft Azure, Google Compute Engine, and Amazon Web Services are some leading IaaS cloud service providers.

There are some prominent characteristics of IaaS -

  • GUI and API-based access is available
  • Services provided are highly scalable
  • Resources are available as a service
  • Automated administrative tasks
  • Dynamic and flexible routine

Platform as a Service (PaaS)


This cloud computing platform is created for programmers to test, develop, run, and manage applications.


Implementing this service simplifies the process of organization software development. The virtual runtime atmosphere provided by this service gives a convenient space for testing and developing applications. The servers, storage, and networking provided are manageable either by the firm or a platform provider.


There are various occasions when a Platform-as-a-Service (PaaS) would be a great idea. For example, if you have several developers working on the same development project, PaaS would be a great way to streamline the workflow.


There are some prominent characteristics of PaaS -


  • Accessible to various users via the same development application.
  • Provides an ability to "Auto-scale".
  • Support multiple languages and frameworks.
  • Integrates with databases and web services.
  • Builds on virtualization technology, which eases resources to be easily scaled up or down as per the business need. 

Software as a Service (SaaS)


This service is also known as "on-demand software". It is software in which the applications are entirely hosted by a cloud service provider. Users can easily access these applications and data with the help of an internet connection and web browser. This service offers software tailored to the organization’s individual needs.  Just like IaaS, customers have access to servers and data centers managed and maintained by third-party providers.


These are the prominent characteristics of SaaS -


  • Easily accessible over the internet
  • Managed from a central location
  • Updates are applied automatically.
  • Services can be hosted on a remote server
  • The services are purchased on the pay-as-per-use basis
