However, when the application grows and needs to run across 3 to 4 different servers, you will be shocked to realize that pure Docker is simply not enough. A broken cable, a power outage, or just a node catching fire — who will automatically move your application to a healthy node? That&rsquo;s exactly when we need Orchestration, specifically the Kubernetes ecosystem.</p>https://vinhmdev.com/posts/intro-a-tale-of-2-servers-udp-ports-and-k3s/Sun, 12 Apr 2026 00:00:00 +0000https://vinhmdev.com/posts/intro-a-tale-of-2-servers-udp-ports-and-k3s/<h2 id="the-unintended-cluster-origin" class="relative group">The Unintended Cluster Origin <span class="absolute top-0 w-6 transition-opacity opacity-0 -start-6 not-prose group-hover:opacity-100"><a class="group-hover:text-primary-300 dark:group-hover:text-neutral-700" style="text-decoration-line: none !important;" href="#the-unintended-cluster-origin" aria-label="Anchor">#</a></span></h2><p>It all started with an incident that was somewhat&hellip; ironically amusing.</p> <p>I had a web project that needed to be deployed urgently. Instead of renting a VPS online as usual, I texted a senior friend in the industry to ask if he had any spare servers to let me use. Very enthusiastically, he immediately threw me the details of a server to get to work.</p>
