What is AWS's responsibility under the shared responsibility model?

Under the shared responsibility model, AWS takes on specific responsibilities to ensure the security and availability of its cloud infrastructure. One of these key responsibilities is restricting access to data centers. This involves implementing rigorous physical security measures to protect the facilities that house AWS's hardware, ensuring that only authorized personnel have access to these locations. This is a fundamental aspect of the cloud provider's duties, as it helps safeguard the underlying infrastructure that customers rely on for their services.

The shared responsibility model delineates the division of security responsibilities between AWS and its customers. While AWS manages the security of the cloud (including the physical security of data centers), customers are responsible for securing their applications and data within that cloud. Understanding this model is crucial for managing security in the cloud effectively.
