Cloud computing services are categories mainly three types as below:
1. SAAS - Software as a services
2. PAAS - Platform as a services
3. IAAS - Infrastructure as a services
As in the above picture you can see end use can hit only SAAS model and internally SAAS hit to PAAS and IAAS.
1. SAAS (Software as a services):
II. Communications As A Service (CAAS)
III. Network As A Service (NAAS)
IV. Monitoring As A Service (MAAS)
1. SAAS - Software as a services

1. SAAS (Software as a services):
- SASS services = SAAS + PASS + IAAS
- This services is just start using the software after getting the license or free one just need to register and start using.

3. IAAS (Infrastructure as a services):
- IASS is purely hardware environment and this includes virtual machine,storage, load balancing and networking.
- This can quickly scales up and down on demand.
4. Other cloud services:
I. FAAS (Function as service) : This follow the serverless architecture.II. Communications As A Service (CAAS)
III. Network As A Service (NAAS)
