Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

Which service allows for creating and managing applications without having to manage the underlying infrastructure?

1. Infrastructure as a Service (IaaS)

2. Platform as a Service (PaaS)

3. Software as a Service (SaaS)

4. Function as a Service (FaaS)

The correct answer is: Platform as a Service (PaaS)

Platform as a Service (PaaS) provides a complete development and deployment environment in the cloud, allowing developers to build, manage, and run applications without worrying about the underlying infrastructure. With PaaS, users can focus on the creative aspects of app development, such as coding and testing, rather than dealing with the hardware, servers, storage, network configuration, or operating systems that support their applications. PaaS typically includes a set of tools and services to facilitate the development process, including integrated development environments (IDEs), application hosting, database management, and middleware. This model streamlines the application development lifecycle, enabling faster delivery of applications and innovation by abstracting and managing the complexities of the infrastructure. In contrast, Infrastructure as a Service (IaaS) offers virtualized computing resources over the internet, which necessitates the management of servers, storage, and network resources. Software as a Service (SaaS) delivers software applications over the internet on a subscription basis, focusing more on end-user interaction rather than application development itself. Function as a Service (FaaS) is a serverless computing model that allows developers to run code in response to events but still requires consideration of the code execution context. By utilizing PaaS
