1. Stand-alone Virtualization
Definition: A virtualization deployment where a single hypervisor host runs one or more virtual machines (VMs) without being part of a cluster or shared environment.
Characteristics:
- No integration with other hypervisor nodes.
- VMs are tightly bound to the local compute and storage resources of that one host.
- Lacks features like automatic failover, centralized monitoring, or distributed resource scheduling.
- Useful for isolated workloads with minimal fault tolerance needs.
Technologies/Tools:
- VMware Workstation, Oracle VirtualBox, Microsoft Hyper-V (local instance)
Limitations:
- No High Availability (HA) – if the host fails, all VMs are lost until the host is manually restored.
- No scalability – adding new resources requires manual setup and migration.
- Single point of failure for both compute and storage.
Example: A software engineer uses VirtualBox on their laptop to spin up Ubuntu, Kali Linux, and Windows 10 VMs for testing multi-platform applications.
