title: What is a headless service, what does it do/accomplish, and what are some legitimate use cases for it?
body: <p>I've read a couple of passages from some books written on Kubernetes as well as the <a href="https://kubernetes.io/docs/concepts/services-networking/service/#headless-services" rel="noreferrer">page on headless services in the docs</a>. But I'm still unsure what it really actually does and why someone would use it. Does anyone have a good understanding of it, what it accomplishes, and why someone would use it?</p>
