Virtualization
Virtualization is a technology that creates virtual versions of physical computing resources, such as servers, storage devices, networks, or operating systems. It allows multiple virtual machines (VMs) or containers to run on a single physical machine by abstracting the underlying hardware, enabling efficient resource utilization and isolation. This concept is fundamental in cloud computing, data centers, and modern IT infrastructure for scalability, flexibility, and cost savings.
Developers should learn virtualization to build scalable and portable applications, especially in cloud-native and DevOps environments. It is essential for creating isolated development and testing environments, deploying microservices in containers, and managing infrastructure in platforms like AWS, Azure, or Kubernetes. Use cases include server consolidation, disaster recovery, and enabling multi-tenancy in software-as-a-service (SaaS) applications.
