Introduction to Virtualization
Virtual Machines (VMs) are software-based computers that run on your physical hardware, allowing you to create isolated environments for development and testing. This is particularly useful in DevOps where consistency across different stages of the deployment pipeline is crucial.
Key Concepts
- Host Machine: The physical machine running the virtualization software.
- Guest VMs: Virtual machines running inside the host machine.
- Bridged Adapter: Assigns a real IP address to the guest VM, allowing it to communicate directly with other devices on your network.
- NAT (Network Address Translation): Isolates the guest VM from external networks but allows it to
