Google Cloud Digital Leader Practice Exam

Which cloud computing service model provides an environment to develop and deploy cloud applications?

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)

The selected answer, Platform as a Service (PaaS), is the correct one because PaaS specifically offers an environment that allows developers to build, deploy, and manage applications without having to handle the underlying infrastructure. PaaS provides a comprehensive set of tools and services that streamline the development process, such as application hosting, middleware, development frameworks, and database management. This model allows developers to focus on writing code and building applications rather than worrying about the hardware or operating system, making it ideal for software development and deployment. In contrast, Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet but requires users to manage everything from the operating system upwards, including installing and configuring software applications. Software as a Service (SaaS) delivers fully functional applications over the internet, often eliminating the need for users to manage software installation or maintenance, but it does not provide a development platform. Function as a Service (FaaS) allows developers to run code in response to events, focusing on executing small units of code. While it supports application development, it lacks the broader environment and integrated tools that PaaS provides for more comprehensive application development and deployment.
