IaaS (Infrastructure as a Service) is a cloud computing model that delivers on-demand infrastructure resources to organizations via the cloud, such as compute, storage, networking, and virtualization1. Customers do not have to manage, maintain, or update their own data center infrastructure, but are responsible for the operating system, middleware, virtual machines, and any apps or data1. Therefore, IaaS gives customers full control over the operating system(s) running on their cloud computing platform, as well as the flexibility to customize and configure their infrastructure according to their needs2. References: What are the different types of cloud computing? | Google Cloud, PaaS vs IaaS vs SaaS: What’s the difference? | Google Cloud
