Virtualization: Run Multiple Systems on One Machine

Virtualization allows you to run multiple operating systems simultaneously on a single physical machine. Hypervisors like VMware ESXi, KVM, Hyper-V, and VirtualBox create isolated virtual machines (VMs) that behave like independent physical computers.

Virtualization is fundamental to modern IT — from development environments and testing labs to production server consolidation and cloud computing. Our books cover both Type 1 (bare-metal) and Type 2 (hosted) hypervisors.

• Resource Efficiency: Run 10+ servers on one physical machine
• Cost Savings: Reduce hardware, power, and cooling costs
• Cloud Foundation: Cloud computing is virtualization at scale
• Development: Instantly create and destroy test environments
• Disaster Recovery: VM snapshots and live migration

• System Administrators: Manage virtual infrastructure
• Developers: Create isolated development environments
• IT Students: Build practice labs without multiple machines
• Cloud Engineers: Understand the foundation of cloud services

• VMware vSphere and ESXi
• KVM and QEMU on Linux
• Hyper-V on Windows Server
• VirtualBox for desktop virtualization
• VM management and optimization
• Snapshots and cloning
• Live migration and high availability
• Storage for virtual environments
