The shared responsibility model in cloud computing delineates the responsibilities of both the cloud provider and the customer:

Shared Accountability:

Infrastructure Security: Both the cloud provider and the customer share responsibility for securing the infrastructure. The provider ensures the security of the physical infrastructure and foundational services, while the customer is responsible for securing their applications, data, and configurations.

Provider Responsibilities:

Physical Infrastructure: The cloud provider manages and secures the physical data centers, servers, networking, and storage. This includes ensuring physical security, hardware maintenance, and infrastructure resilience.

Basic Services: The provider also secures the underlying services such as virtualization, network, and storage infrastructure.

Customer Responsibilities:

Application and Data Security: Customers are responsible for securing their applications, data, and configurations. This includes implementing security measures such as encryption, access controls, and monitoring within their cloud environment.

Compliance and Governance: Customers must ensure their use of the cloud services complies with relevant regulations and governance standards.
