Understanding PaaS vs SaaS vs IaaS: Detailed Differences and Use Cases

In the present day, cloud services are raging in the market. Many IT giants provide a range of cloud services at competitive prices. Emerging business owners in the market are unaware of the exact difference between these offerings and are unaware of which option fits best for their business.

There are three crucial cloud concepts, namely PaaS (Platform as a Service), SaaS (Software as a Service) and IaaS (Infrastructure as a Service). There are more subsets of cloud models that include CaaS (Container as a Service), DaaS (Desktop as a Service), etc. Here we will break down the differences between the top 3 cloud concepts that can help you decide which fits perfectly to fulfil your business needs.

To start with, let us first understand cloud computing basics

Software as a Service

Software as a Service allows end-users to connect to and use the cloud-based apps over the internet like emails, calendar, Microsoft Office 365, Google G-Suite etc.

Cloud vendors provide the complete freedom to work on the procured software, which is entirely maintained and managed by the vendors without worrying about the underlying infrastructure and updating the software for security patches.

For organizational use, we can rent sophisticated business applications such as customer relationship management (CRM), enterprise resource planning (ERP) and document management and pay for using these apps by subscription.

Platform as a Service:

Platform as a Service supplies an on-demand environment for developing, testing, delivering and managing software applications. It makes development easier for developers to create mobile or web apps faster, without worrying about the underlying infrastructure like servers, storage, networking.

PaaS Characteristics:

Use Cases:

When multiple developers or external parties are working on the development project, PaaS is the best option to bring speed and flexibility to the development process.

Infrastructure as a Service

It is the most basic computing service that rents essential compute, storage, networking, and operating system resources on-demand on the pay-as-you-go model. Migrating your organization’s IT infrastructure to the cloud reduces the maintenance of the physical data centre, saves money, and gains some real-time business insights.
