Let us talk about them.


What are Cloud Service Models and Their Types?

Cloud service model is a term that defines the method of how a cloud service provider delivers cloud services to its customers and how it is managed. There are three main types of cloud service models that a provider can serve and a user can avail of – SaaS, IaaS, and PaaS.

You can access these through the internet via web browsers or web applications that are available on the market. The cloud service models are designed to enable various teams to collaborate online on a single platform for their work.

Instead of relying on-premises software or their local servers, companies are now preferring to outsource their storage requirements to cloud service providers. This has benefitted the companies by relieving them from the responsibility of maintaining infrastructure and ensuring data safety.

So, here is a brief description of the cloud service models to help you know them better.


Software as a service or SaaS is a cloud-based delivery model for software services. In this model, the cloud provider develops and maintains cloud application software.  It offers automatic updates for SaaS applications and makes software available to the users via the Internet.

It is a pay-as-you-go service that can be used for free with limited access to features or by a paid licensed subscription with a wider variety of features available.

Since it is a cloud-based service, the SaaS cloud model requires no installations or downloads in your current on-premise software infrastructure. This will exempt your organization from the pain of installing the software to each computer and the effort required for supporting and maintaining it.

Where initially SaaS was designed to serve a single business purpose, it has now evolved to connect varied sections from financials, procurements, supply chains, human resources, and every other requirement to run your business processes. Some examples of SaaS are Dropbox, Google Docs, Microsoft Office 365, etc.


Infrastructure as a Service or IaaS is one of the primary types of cloud computing model which essentially provides virtual computer resources including computing, storage, and network resources through the cloud.

An IaaS cloud provider may supply you with basic software infrastructure along with maintenance and support of the software system. It is an on-demand service based on a pay-as-you-go policy.

You may choose and use the computer resources you need for your business objectives without having to actually deploy hardware on your premises.

Migrating your organization’s infrastructure to an IaaS cloud solution will allow you to lower your on-premises data center maintenance, save money on hardware expenditures, and receive real-time business analytics. IaaS solutions allow you to scale your IT resources up and down according to the demand.

They also assist you in swiftly provisioning new apps and enhance the resilience of your underlying infrastructure. Some of the leading IaaS cloud service providers are Amazon Web Services, Google Compute Engine, and Microsoft Azure.


Platform as a Service or PaaS, is simply a cloud platform where you can build, test, and organize various applications for your organization. It is basically working on an operating system from a remote server. Implementing PaaS will streamline your company’s entire software development process.

Further, its virtual runtime environment provides an ideal platform for creating and testing apps. It is subscription-based and offers variable pricing choices based on your business’s needs.

It is either your company or your cloud service provider that is in charge of managing the full set of cloud resources available in the form of servers, storage, and networking.

In short, PaaS is a flexible, scalable cloud platform where you can develop, deploy, run, and manage varied apps. Examples of PaaS include Google App Engine and AWS Elastic Beanstalk.


Choosing between SaaS, IaaS, PaaS

Before you choose any one of the cloud service models, let us put them under close inspection. This will help you choose the best fit for your company.

Benefits of SaaS

  • Affordability: SaaS is affordable as it helps reduce the expenditures associated with purchasing, installing, maintaining, and upgrading computing hardware.
  • Accessibility: Global accessibility, access from anywhere using any device eliminating the pressure on on-premise infrastructure.
  • Ready to use: SaaS services may be easily set up and made operational. To have access to quick and powerful computer resources, you need to simply sign up for the service.

Benefits of IaaS

  • Cost-effectiveness: Using an IaaS cloud architecture eliminates the need to deploy on-premise hardware, lowering expenses.
  • Scalability: IaaS is the most adaptable cloud computing platform that enables you to scale your computer resources up or down in response to demand.
  • Easy deployment: IaaS allows you to install servers, processing, storage, and networking to get up and running in no time.

Benefits of PaaS

  • Cost-effectiveness: PaaS is cost-effective as it allows access to most state-of-the-art resources without paying much for them.
  • Reduced development time: As the computing resources involved are provided by the cloud service providers, it reduces the development time.
  • Multiple language support: PaaS supports multiple programming languages enabling developers to seamlessly build applications for different projects.
  • Improved collaboration: PaaS can assist in connecting your team distributed in various locations and integrating their tasks on a single platform. Thus, PaaS gives you enhanced team collaboration.
