Infrastructure as a Service (IaaS): The provider offers computing resources such as servers, storage, networks and virtual machines that users can rent and manage via a web portal or an API. Examples: Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP).

Platform as a Service (PaaS): The provider offers a web-based environment where developers can build cloud applications using a database, operating system and programming language provided by the provider. Examples: Heroku, Google App Engine, AWS Elastic Beanstalk.
