Virtual Machines: Foundations of System and Process Virtualization

Virtualization is the backbone of modern cloud computing and system administration, yet how virtual machines actually operate remains a mystery to many. This text-based course demystifies the inner workings of both system-level and process-level virtual machines. You will transition from simply using virtual machines to understanding their core architecture, execution engines, and resource management strategies, enabling you to optimize applications with confidence. What you'll learn: 1. Understand the core differences between system virtual machines and process virtual machines. 2. Learn how hypervisors manage CPU, memory, and I/O virtualization. 3. Explore the internals of managed runtimes, including bytecode execution and garbage collection. 4. Compare traditional virtualization with modern containerization and microVM architectures. 5. Practice analyzing resource allocation and isolation boundaries. Starting with fundamental definitions and key terminology, the course guides you through hypervisor architecture, memory virtualization, managed runtimes, and modern cloud-native virtualization techniques. This course is designed for beginner software developers, system administrators, and computer science enthusiasts who want a solid conceptual foundation in virtualization, with no prior systems programming experience required.
