Which cloud service model is best suited for developers looking to build applications without managing the underlying infrastructure?

1. IaaS

2. SaaS

3. PaaS

4. DaaS

The correct answer is: PaaS

The Platform as a Service (PaaS) model is specifically designed for developers who want to focus on building and deploying applications without the complexity of managing the underlying infrastructure. In the PaaS model, the cloud provider takes care of the hardware, networking, storage, and operating system, allowing developers to concentrate on writing code and developing applications. This means that developers can quickly create applications without worrying about setting up and maintaining servers, networks, and databases. PaaS provides development tools, middleware, and database management systems within its platform, which further accelerates the development process. This model also supports collaboration among development teams, making it easier for multiple developers to work on the same application from different locations. In contrast, models like Infrastructure as a Service (IaaS) require users to manage and configure the underlying infrastructure, which may not suit developers who prefer to focus on high-level application development. Software as a Service (SaaS) delivers fully functional applications to users but does not provide the flexibility for developers to build and develop new applications. Data as a Service (DaaS) generally refers to the delivery of data on demand, which is not directly relevant to application development. Hence, PaaS is the optimal choice for developers looking
