A developer is creating a new web application but does not want to be responsible for server or infrastructure maintenance. Which of the following cloud models is MOST likely to be used by the develop

Private cloud means the organization owns and manages the entire infrastructure, which directly contradicts the developer's desire to avoid maintenance responsibilities.

SaaS (Software as a Service) delivers ready-to-use applications to end-users and is not a platform for developing new applications.

PaaS (Platform as a Service) removes even more responsibility, including operating system and runtime management, but IaaS still satisfies the condition of not being responsible for *server or infrastructure maintenance* at the physical hardware level.

Hybrid cloud is a deployment model combining private and public clouds, not a service model that defines the level of infrastructure management by the user for a new application.

IaaS (Infrastructure as a Service) provides virtualized computing resources where the cloud provider manages the physical servers, networking hardware, and virtualization infrastructure. This allows the developer to avoid responsibility for physical server maintenance and infrastructure operations, while still having control over the operating system and applications.
