VMDK
VMDK (Virtual Machine Disk) is a file format used to store the contents of a virtual machine's hard disk drive in virtualization environments. It encapsulates disk data, including partitions, file systems, and files, allowing it to be used as a virtual disk by hypervisors like VMware vSphere, Workstation, and Fusion. The format supports features such as snapshots, thin provisioning, and encryption, making it integral to virtual machine management and deployment.
Developers should learn VMDK when working with VMware-based virtualization, as it is the default disk format for VMware products, essential for creating, managing, and migrating virtual machines. Use cases include setting up development or testing environments, deploying applications in virtualized data centers, and performing backups or disaster recovery using VM snapshots. Knowledge of VMDK is also valuable for integrating with cloud platforms like VMware Cloud on AWS or automating VM provisioning with tools like Terraform.
