IaaS offers virtualized computing resources over the internet, providing users with access to virtual machines, storage, and networking infrastructure. It allows users to deploy and manage virtualized servers and other infrastructure components, giving them control over the hardware environment on which they can develop, deploy, and run their solutions. While PaaS (Platform as a Service) provides a platform with development tools and runtime environments, it does not typically offer access to the underlying hardware components in the same way that IaaS does. PaaS abstracts away the hardware layer, allowing developers to focus on building and deploying applications without managing the infrastructure.

When considering cloud models, the one that provides hardware environment equivalent components for developing a solution is Infrastructure as a Service (IaaS)
