The three main types of cloud computing as-a-service options are infrastructure, platform, and
software. Each one covers a different level of management for you:
IaaS (Infrastructure as a Service): IaaS includes all of the infrastructure components that
are needed to run your applications, such as servers, storage, and networking.
PaaS (Platform as a Service): PaaS provides a platform for you to develop and deploy your
applications. This can include tools for development, testing, and deployment.
SaaS (Software as a Service): SaaS is a complete application that is offered to users over
the internet. This means that you do not need to install or manage any software on your own.
