What technology allows for the implementation of secure, shared resources in a cloud environment?

1. Virtualization

2. Containerization

3. Multi-tenancy

4. Isolation

The correct answer is: Virtualization

The implementation of secure, shared resources in a cloud environment is best achieved through multi-tenancy. This technology allows multiple customers or "tenants" to share the same infrastructure and resources while keeping their data and applications separate and secure from one another. Multi-tenancy efficiently utilizes resources, leading to cost savings and simplified management for service providers. While virtualization plays a role in creating isolated environments on a single physical machine, it does not specifically address the sharing of resources among different tenants in a cloud environment. Similarly, containerization allows applications to run in isolated environments, but it is not specifically designed for enabling the shared access that multi-tenancy supports. Isolation, while important for security, refers to the separation of different environments or workloads rather than the shared aspect of resources.
