    Question

    Which cloud service model allows developers to deploy

    their applications without managing the underlying infrastructure?
    A Infrastructure as a Service (IaaS) Correct Answer Incorrect Answer
    B Software as a Service (SaaS) Correct Answer Incorrect Answer
    C Platform as a Service (PaaS) Correct Answer Incorrect Answer
    D Functions as a Service (FaaS) Correct Answer Incorrect Answer
    E Database as a Service (DBaaS) Correct Answer Incorrect Answer

    Solution

    PaaS provides a platform where developers can deploy, manage, and test their applications without dealing with hardware provisioning, OS installation, or runtime environments. Services like Microsoft Azure App Services and Google App Engine abstract the complexities of the infrastructure, allowing developers to focus on coding. PaaS also offers pre-configured environments for testing and integration, reducing deployment time significantly. For instance, PaaS is ideal for building web applications where auto-scaling and integrated development tools simplify workflows. Why Other Options Are Incorrect :

    1. IaaS : Provides raw infrastructure like virtual machines, requiring developers to manage the OS and middleware.
    2. SaaS : Delivers ready-to-use software over the internet, unsuitable for custom app deployment.
    3. FaaS : Focused on serverless architectures for small, stateless functions rather than comprehensive applications.
    4. DBaaS : Specifically for database provisioning, not a general-purpose application development platform.
