DDBaaS

Explanation

IaaS (Infrastructure as a Service) provides virtualized computing resources over the internet, including virtual machines (VMs), storage, and networking. Public cloud IaaS providers such as AWS EC2, Microsoft Azure Virtual Machines, and Google Compute Engine let technicians provision and manage VMs on demand. SaaS (B) delivers complete software applications to end users (e.g., Microsoft 365) and does not expose underlying infrastructure. PaaS (C) provides a platform for developers to build and deploy applications without managing the underlying OS or hardware. DBaaS (D) is a specialized managed database service. Only IaaS gives the technician direct control over a virtual machine.
