OVA
OVA (Open Virtual Appliance) is like a pre-packaged computer system that can be easily moved between different cloud platforms or servers. Think of it as a digital box containing a complete, ready-to-use software setup. When companies need to move their applications or systems from one place to another, they often use OVAs because it's like moving an entire computer system as one neat package, rather than moving all the pieces separately. It's commonly used with systems like VMware and VirtualBox, which are popular tools for running multiple virtual computers on a single physical machine.
