A development team does not want to handle patching or infrastructure and only wants to focus on writing code. Which cloud model fits?

PaaS (Platform as a Service) is the correct choice because it provides a complete development and deployment environment in the cloud, allowing developers to focus solely on writing and deploying their application code. The cloud provider manages the underlying infrastructure, including operating systems, patching, networking, and servers. SaaS (Software as a Service) would be incorrect because it refers to fully managed applications that users consume, not a platform for developing new applications. IaaS (Infrastructure as a Service) is incorrect because while it provides virtualized computing resources, the user is still responsible for managing the operating system, middleware, and runtime, including patching. DRaaS (Disaster Recovery as a Service) is a specific service for disaster recovery, not a general development platform.
