Demystifying the Three Pillars of Cloud Computing: IaaS, PaaS, and SaaS (2024)

FAQs

What are the three pillars of cloud computing? ›

Cloud Computing encompasses three primary categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

3 COMPONENTS OF CLOUD TECHNOLOGY: SAAS, PAAS, AND IAAS

The provider updates, maintains, and rolls out new versions of the software to consumers. Thus, consumers no longer have to purchase every new release of the software.

IaaS builds the infrastructure of cloud-based technology. PaaS helps developers build custom apps via an API that can be delivered over the cloud. And, SaaS is cloud-based software companies can sell and use.

The main three types of cloud computing are public cloud, private cloud, and hybrid cloud. Within these deployment models, there are four main services: infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS), and serverless computing.

Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) are the big three cloud service providers today.

Cloud computing has three main cloud service models: IaaS (infrastructure as a service), PaaS (platform as a service), and SaaS (software as a service).

IaaS, PaaS, and SaaS stand for infrastructure-as-a-service, platform-as-a-service, and software-as-a-service. IaaS provides a pay-as-you-go approach for storage, networking, and virtualization. In addition, PaaS includes even more services like hardware and software development tools available via web.

In a nutshell, IaaS provides access to resources such as virtual machines and virtual storage, PaaS provides execution environments, application development, and deployment tools, and SaaS provides software as a service to end-users.

PaaS is most often built on top of an IaaS platform to reduce the need for system administration. It allows you to focus on app development instead of infrastructure management. SaaS offers ready-to-use, out-of-the-box solutions that meet a particular business need (such as a website or email).

What are the 3 main types of cloud deployment models? ›

The three main types of cloud deployment models are private, public, or hybrid. Selecting your desired model depends on your specific requirements.

Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) are the cloud service providers with the largest market share, collectively capturing over 65% of spending on cloud infrastructure services.

Platform as a service (PaaS) is a cloud computing platform where a third party offers the necessary software and hardware resources. These offerings enable clients to develop, run, and manage business applications without maintaining the infrastructure required for such software development processes.
