Types of cloud computing
Basically, there are 3 types of cloud computing:- Software as a Service (SaaS) - It allows companies to use the software without purchasing them, which reduces the company's expenditure. And since the software is already installed on the cloud server, they can be quickly deployed and help save time.
- Platform as a Service (PaaS) - It allows developers to build applications, data etc. and handles the infrastructure, OS, and services required to run these applications.
- Infrastructure as a Service (IaaS) - It allows companies to rent infrastructure from a cloud provider to run their applications and OS. AWS is more of an IaaS.
