Before we dive deep into choosing which cloud service is best for your company.

What is SaaS?

Software as a service (SaaS) is related to an application hosted by the provider and it will be available to its subscribers on the internet.

SaaS allows its user to download the application by using an internet connection with confirmation on subscription.

SaaS provides the latest up-to-date applications in the latest version to its consumers. This helps developers to maintain revenue for maintaining their product.

What is PaaS?

Platform as a service (PaaS) provides the entire cloud environment for the process of development on the internet for developers.

It allows developers to create simple to complex and hybrid cloud apps for business software.

Likewise, SaaS provides up-to-date latest technological versions with tools to reduce the cost of getting the latest versions. So it is quite similar to SaaS in maintenance.

What is IaaS?

Infrastructure as a Service (IaaS) allows users to perform many tasks with their hardware.

This is majorly used by service providers who maintain their own data centers. This includes on-premise storage space, advanced computing, or special processors services.
