Which term includes delivering hosted services over the internet, such as infrastructure as a service or platform as a service?

The term that encompasses delivering hosted services over the internet, including infrastructure as a service (IaaS) and platform as a service (PaaS), is cloud computing. This model allows businesses and individual users to access and utilize computing resources, storage, and application services over the internet without needing to own and manage the underlying hardware and software infrastructure.

Cloud computing provides flexibility, scalability, and cost-effectiveness, as users can pay for these services on a subscription basis instead of investing heavily in physical infrastructure. It facilitates remote access and collaboration by allowing users to work from anywhere with internet connectivity, contributing to operational efficiency and resource optimization.

In contrast, outsourcing generally refers to the practice of hiring external organizations to handle certain business functions, which does not specifically imply service delivery over the internet. Machine learning is a subset of artificial intelligence focused on the development of algorithms and models that allow computers to learn from data, and while it may utilize cloud computing resources, it does not specifically pertain to the delivery of hosted services over the internet.
