Cloud computing is a general term for anything that involves delivering hosted services over the internet
What are the different types of cloud computing services?
Cloud computing can be separated into three general service delivery categories or forms of cloud computing:
1. IaaS
2. PaaS
3. SaaS
IaaS
IaaS providers, such as Amazon Web Services (AWS), supply a virtual server instance and storage,
as well as application programming interfaces (APIs) that let users migrate workloads to a virtual machine (VM).
IaaS providers offer small, medium, large, extra-large, and memory- or compute-optimized instances,
in addition to enabling customization of instances, for various workload needs.
PaaS.
In the PaaS model, cloud providers host development tools on their infrastructures. Users access these tools over the internet using APIs, web portals or gateway software.
PaaS is used for general software development, and many PaaS providers host the software after it's developed.
Common PaaS products include Salesforce's Lightning Platform, AWS Elastic Beanstalk and Google App Engine.
SaaS.
SaaS is a distribution model that delivers software applications over the internet; these applications are often called web services.
Users can access SaaS applications and services from any location using a computer or mobile device that has internet access.
the SaaS model, users gain access to application software and databases. One common example of a SaaS application is
Microsoft 365 for productivity and email services.
