Which cloud computing model allows clients to rent software accessed over the internet?

The model that allows clients to rent software accessed over the internet is Software as a Service (SaaS). This model provides users with access to software applications hosted on a cloud infrastructure, enabling them to use the software via a web browser without the need for local installation or management. Clients benefit from the convenience of subscription-based access, automatic updates, and the ability to scale usage based on their needs. This approach reduces the requirements for physical hardware and IT maintenance, making it an attractive solution for many organizations.

Infrastructure as a Service (IaaS) primarily provides virtualized computing resources over the internet, allowing users to rent virtual machines and other fundamental computing infrastructure. Platform as a Service (PaaS) offers a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. Network as a Service (NaaS) enables users to manage network services and infrastructure on a subscription basis but does not focus on software applications. Each of these models serves different purposes in the cloud computing ecosystem; however, SaaS specifically addresses the requirement for software access over the internet.
