Based on the cloud provider, we are talking about both:
IaaS (Infrastructure-as-a-Service), PaaS (Platform-as-a-Service), SaaS (Software-as-a-Service), or, Storage, Database, Information, Process, Application, Integration, Security, Management, Testing-as a provider.
If the cloud provides a development platform, and this includes an operating system, the application language, website, and web server, the model is called Platform-as-a-Service (PaaS), its possible examples being Google App Engine, Microsoft. Azure, Salesforce. A functional machine can be constantly upgraded and upgraded with PaaS, resources can be accessed from a variety of resources, and editing can be done in groups (distributed locally).
Software-as-a-Service (SaaS), in the end, is approaching where customers are able to access multiple software programs in the payment process through basic deployment. As bad as buying certified packages, they are usually very expensive. I would like to end on the note that cloud computing is the future and I think it is only forward from here on.
