Question
Which of the following best differentiates between
server-based virtualization and hypervisor-based virtualization?Solution
Hypervisor-based virtualization is categorized into two types: Type 1 (bare-metal) and Type 2 (hosted). In Type 1, the hypervisor directly interacts with the hardware, eliminating the need for a host OS. This approach provides better performance and scalability, making it suitable for enterprise-level virtualization. On the other hand, server-based virtualization operates within a host operating system, utilizing software to create and manage virtual machines. This makes it more accessible but less efficient than hypervisor-based solutions. For instance, enterprise environments often use hypervisors like VMware ESXi (Type 1) for better resource management and performance. Why Other Options Are Incorrect :
- Physical vs logical partitioning : Both virtualizations rely on logical partitioning to allocate resources dynamically; this option is incorrect.
- Cross-platform OS : Both types support cross-platform OS, especially in hypervisor-based setups with proper configurations.
- Shared kernel : This describes containerization, not server-based virtualization.
- Hardware-level isolation : Hypervisor-based virtualization provides superior hardware isolation compared to server-based virtualization.
