What is AWS's responsibility under the Shared Responsibility Model?

Under the Shared Responsibility Model, AWS is responsible for maintaining the physical hardware that supports its cloud services. This includes everything from the physical infrastructure, such as servers, storage devices, and data centers, to the security and maintenance of that hardware. AWS ensures that these components are secure, resilient, and available for use within their cloud environment.

This division of responsibilities allows users to focus on securing their applications and data without needing to worry about the underlying infrastructure. In contrast, application-level security, user data encryption, and network traffic routing are typically the responsibilities of the customer. Each party has clear areas of focus that collectively contribute to the security and functionality of cloud services.
