Which cloud service category grants access to an application platform?

1. IaaS

2. PaaS

3. SaaS

4. TaaS

The correct answer is: PaaS

PaaS, or Platform as a Service, is the correct answer because it specifically provides a platform that allows developers to create, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. PaaS solutions include middleware, development tools, database management systems, and other services that help streamline the application development process. In contrast, IaaS, or Infrastructure as a Service, offers virtualized computing resources over the internet but does not specifically focus on application platforms. It provides the basic infrastructure such as servers, storage, and networking capabilities, which developers would still need to manage and configure to build applications. SaaS, or Software as a Service, delivers software applications via the internet on a subscription basis and is fully managed by the service provider. While it provides users access to applications, it does not offer the same level of control and flexibility in application development and deployment that PaaS does. The term TaaS, or Testing as a Service, is not a widely recognized cloud service model and generally refers to cloud-based testing services, which do not encompass the broader application platform capabilities intrinsic to PaaS. Thus, PaaS is indeed the service category that directly grants access to
