What does the 'shared responsibility model' in cloud computing define?

The 'shared responsibility model' in cloud computing is fundamentally about defining the distinct security responsibilities of the cloud provider and the customer. Under this model, the cloud provider is responsible for securing the infrastructure (including hardware, software, networking, and facilities) that supports the cloud services. In contrast, the customer is responsible for securing their own data, managing access controls, and configuring the services properly.

This delineation helps both parties understand their roles and responsibilities when it comes to security and compliance. For instance, while a cloud provider may ensure that their data centers are secure, the customer must ensure that their applications and data are protected from unauthorized access and breaches.

The other choices do not accurately reflect this central concept. The separation of data is not a core element of the model; it specifically addresses security responsibilities rather than just data separation. Cost allocation pertains to pricing structures in cloud service models and does not relate to security responsibilities. Licensing agreements are more about how software can be used rather than defining roles in security between the provider and the customer.
