Multi-tenancy is a fundamental characteristic of cloud computing, where multiple customers share the same physical infrastructure while maintaining separate and secure environments for their data and applications. This structure can lead to shared security responsibility because both the cloud service provider and the customers must collaborate to ensure adequate security measures are in place.

In a multi-tenant environment, the cloud service provider is responsible for securing the underlying infrastructure, including physical hardware, virtualization layers, and network connectivity. Meanwhile, customers are responsible for securing their own applications, data, and access controls. This division of responsibilities creates a shared security model, where both parties take active roles in maintaining security and compliance.

Understanding this shared security responsibility is crucial because it highlights the importance of both provider and customer involvement in safeguarding cloud environments. Organizations leveraging multi-tenant cloud services must recognize their role in protecting their data and configurations to mitigate risks effectively.
