Cloud Computing- The 3 Service Delivery Models

Cloud Computing- The 3 Service Delivery Models

01 Feb 2023

Cloud computing refers to the on-demand availability of different computing resources. These include things like networking, storage, data management, etc. This technology paradigm is best for companies who are looking to optimize their business processes. This concept is a mesh of different tools and terminologies. In this blog, we will learn about the 3 main service delivery models of cloud computing.

Benefits of Cloud Computing

Cloud offers the following benefits to the SMEs as well as large business enterprises:

  • Cost optimization
  • Scalability
  • Flexibility
  • Data loss prevention
  • Increased collaboration
  • Faster time to market

Apart from these, there are numerous other benefits of this technology. However, the ones mentioned above are the most prominent ones.

Cloud Computing Service Delivery Models

Cloud, primarily offers three main service delivery models i.e. SaaS, PaaS, and IaaS. We will separately explain each of these below:


Software as a Service (SaaS)

Software as a Service (SaaS) is the most common cloud computing model. It provides end users with the software and applications hosted by others. All the end users need is a browser and a good Internet connection. With these two conditions met, they can access any SaaS application out there. Examples include Gmail, Microsoft Office 365, Slack, etc. The benefits of using SaaS include cost savings since you do not need to purchase any expensive licenses. Also, the software management and updates are entirely handled by SaaS providers. 

Platform as a Service (PaaS)

At times, SMEs are good at developing software and applications. However, they find it hard to acquire the underlying platforms. PaaS provides ease to such businesses by leveraging the underlying platforms as a service. This service delivery model is best suited for organizations that wish to simplify app development and management. PaaS offloads the burden of managing the underlying infrastructure from the shoulders of an organization. Thus the organization can focus more on its production than on management. Examples include Google App Engine, Adobe Commerce, AWS Elastic Beanstalk, etc.

Infrastructure as a Service (IaaS)

The cloud computing model that offers the maximum control to the end users is IaaS. It is such an interesting model of the cloud in which the infrastructure is not hosted on-site. Rather the infrastructure is hosted by the cloud but you have complete access to it. IaaS allows you to get the maximum benefit out of all the hardware and software resources. Meanwhile, their management is entirely handled by the cloud service provider. For example, Google Compute Engine, Microsoft Azure, Amazon Web Services, etc. all follow the IaaS model.

Which Cloud Computing Service Delivery Model is Best for You?

All three cloud computing models offer exceptional benefits. However, you still have to decide which model best suits your needs. If you want to run multiple applications without paying for their licensing, then SaaS should be your choice. For having a platform to run diverse applications, you should consider PaaS. Finally, for optimizing infrastructure costs to the fullest, you should go for IaaS.


Cloud computing has indeed revolutionized the entire world of technology. Therefore, if you are looking to increase your business productivity, you should instantly choose the best service delivery model for you. However, if you want to go for SaaS, then you should take the services of Folium AI.
