FreeBSD on Firecracker
I'm not wanting to sound snoody. What use-cases do firecracker instances and the likes chime?<p>I use FreeBSD for everything from my colocated servers, to my own PC. By no means am I developer; seasoned Unix Admin at best. Bare-metal forever but welcome to the future. Especially anything that contributes to the OS.<p>However I hear buzz words like Lambda and Firecracker and really have no idea where the usage is. I get docker, containers, barely understand k8s but why do you need to spin up a VM only to tear it down compared to where you could just spin up a VM and use it when you really need to. Always there, always when.<p>Is it purely a cloud experience, cost saving exercise?
