Cloud Computing is primarily broadly categorized as:

1. Infrastructure-as-a-Service.

2. Platform-as-a-Service.

3. Software-as-a-Service.

Infrastructure as a service (IaaS) is a type of cloud computing service that offers essential compute, storage and networking resources on demand, on a pay-as-you-go basis.

Software as a service (SaaS) is a software distribution model in which a cloud provider hosts applications and makes them available to end users over the internet. 

Cloud platform services, also known as Platform as a Service (PaaS), provide cloud components to certain software while being used mainly for applications. 

Big data as a service (BDaaS) is the delivery of data platforms and tools by a cloud provider to help organizations process.
