AWS (Amazon Web Services) Certification Practice Exam

Which of the following cloud service models is designed for application deployment, allowing developers to build, test, and deploy their applications?

1. Infrastructure as a Service (IaaS)

2. Software as a Service (SaaS)

3. Platform as a Service (PaaS)

4. Network as a Service (NaaS)

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

Platform as a Service (PaaS) is specifically designed to facilitate application deployment by providing a comprehensive environment for developers to build, test, and deploy applications. PaaS offers a set of tools and services that extend beyond just computing resources, enabling developers to focus on the creative aspects of application development without having to manage the underlying infrastructure, such as servers or storage. With PaaS, developers can take advantage of pre-configured infrastructure, middleware, and development frameworks that streamline the workflow from coding to deployment. This model significantly enhances productivity since it allows developers to collaborate, automate testing and deployment, and scale their applications as needed without getting bogged down by infrastructure management. In contrast, the other cloud service models serve different purposes. Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, granting users control over operating systems and applications but requiring more management effort. Software as a Service (SaaS) delivers fully functional applications over the internet, which users access directly, but does not allow for custom application development. Network as a Service (NaaS) focuses on networking capabilities and connectivity options rather than application development. These distinctions highlight why PaaS stands out as the optimal model for developers looking to deploy applications
