Unikernel

So, you know how your computer needs an operating system like Windows or Mac OS to work? Well, a unikernel is kind of like a really special operating system.

Instead of being big and complex like those other operating systems, a unikernel is teeny tiny - it's designed to do only one thing really well. That means it can get the job done quickly and efficiently.

For example, let's say you want to make a website. Using a regular operating system like Windows or Mac OS, you'd need to install a big web server program that can do all sorts of things. But with a unikernel, you can just include the specific parts of the web server that you need. That way, the unikernel is smaller and faster, and it focuses only on the tasks you need it to do.

Think of it like a really simple tool - a hammer is just for hitting nails, right? It's not a saw or a screwdriver. In the same way, a unikernel is just for doing one thing, but it does that one thing really, really well.
