Which cloud model allows developers to focus on coding without managing the underlying infrastructure?

The Platform as a Service (PaaS) model is specifically designed to enable developers to focus on writing and deploying code without the need to manage the underlying infrastructure. PaaS provides a comprehensive environment that includes the hardware, software, and tools necessary for development, often including databases, middleware, and development frameworks. This abstraction allows developers to concentrate on their application logic and user experience rather than on server management, network configurations, and other infrastructure-level tasks.

PaaS environments often come with built-in scalability, so applications can automatically adjust to changing demand, and include integrated development tools that expedite the coding process. This significantly enhances developer productivity, as they can leverage cloud services for application hosting and deployment while benefiting from the flexibility and efficiency that a managed platform provides.

The other options represent different cloud models with varying levels of control and management responsibilities. Infrastructure as a Service (IaaS) offers the most control over the infrastructure and requires users to manage operating systems, storage, and networks, while Software as a Service (SaaS) provides complete software applications on a subscription basis, but offers no control over the underlying platform. Function as a Service (FaaS) allows for event-driven execution of code, but is typically seen as a more
