Final answer:
Devices in a virtualized data center are characterized by their ability to be managed separately from the physical hardware. This separation provides flexibility and efficiency in resource management but does not inherently make the system more secure or use fewer resources compared to physical data centers.
Step-by-step explanation:
A fundamental characteristic of devices in a virtualized data center is that they are manageable separately from the underlying hardware. Virtualized environments allow for the abstraction of server, storage, and networking resources, meaning that these resources can be managed, allocated, and re-allocated independently of the physical devices they reside on. This capability is crucial to the efficiency and flexibility of virtualized data centers, enabling IT administrators to optimize resources, perform maintenance without significant downtime, and quickly adapt to changing business needs.
While virtualization can improve resource utilization and may reduce some costs associated with physical hardware, it does not inherently use less resources than devices in a physical data center. Moreover, virtualized devices can indeed be accessed from anywhere on the Internet provided there are appropriate network configurations and security measures in place, making them highly available. However, security is a complex topic, and while virtualization can offer certain security benefits through isolation and encapsulation, it does not automatically make systems 'more secure' and introduces its own unique security considerations.
