The cloud computing service model in which a provider’s applications run on a cloud infrastructure and the consumer does not manage or control the underlying infrastructure is known as:1 pointInfrastructure as a Service (IAAS)Software as a Service (SAAS)Platform as a Service (PAAS)Identity as a Service (IDAAS)

Sure, let's break down the question step by step to find the correct answer.

1. Understanding the Question:

   • The question is asking about a cloud computing service model.
   • In this model, the provider's applications run on a cloud infrastructure.
   • The consumer does not manage or control the underlying infrastructure.

2. Analyzing the Options:

   • Infrastructure as a Service (IAAS):
     • Provides virtualized computing resources over the internet.
     • Consumers manage the operating systems, applications, and data.
     • The underlying infrastructure is managed by the provider.
   • Software as a Service (SAAS):
     • Delivers software applications over the internet.
     • The provider manages the infrastructure, including servers, storage, and networking.
     • Consumers use the applications without managing the underlying infrastructure.
   • Platform as a Service (PAAS):
     • Provides a platform allowing customers to develop, run, and manage applications.
     • Consumers manage the applications and data.
     • The underlying infrastructure and platform are managed by the provider.
   • Identity as a Service (IDAAS):
     • Provides identity and access management services.
     • Focuses on authentication and identity management.
     • Not directly related to running applications on a cloud infrastructure.

3. Matching the Description:

   • The description specifies that the consumer does not manage or control the underlying infrastructure.
   • The provider's applications run on the cloud infrastructure.
   • This matches the characteristics of Software as a Service (SAAS).

4. Conclusion:

   • The cloud computing service model described in the question is Software as a Service (SAAS).

So, the correct answer is: Software as a Service (SAAS).

     • Provides a platform allowing customers to develop, run, and manage applications.
     • The provider manages the infrastructure and platform.
     • Consumers manage the applications they develop.

     • Focuses on authentication and identity management.
     • Not directly related to running applications on a cloud infrastructure.

3. Matching the Description:

   • The description specifies that the consumer does not manage or control the underlying infrastructure and that the provider's applications run on the cloud.
   • This matches the characteristics of Software as a Service (SAAS), where the provider manages everything, and the consumer simply uses the application.

4. Conclusion:

   • The correct answer is Software as a Service (SAAS).

So, the cloud computing service model described in the question is known as Software as a Service (SAAS).
