In this video, I break down the real-world answer to “Docker vs Kubernetes” — and it’s not what most people expect. If you’re running three microservices, you don’t need Kubernetes. I explain why Docker Compose is the best starting point when you have less than ~5 services and a small team. One docker-compose.yml is enough to run a solid multi-container stack, ship fast, and avoid adding complexity you simply don’t need yet. Then I tell you exactly when Kubernetes actually makes sense in production: when you cross the threshold of 10+ services, your team grows (think 15+ people), or you genuinely need independent scaling and high availability. Compose scales your whole stack together, which means if one service needs more capacity, you may end up scaling databases/caches along with it whether they need it or not. Kubernetes, on the other hand, scales individual services based on demand and spreads workloads across multiple nodes so failures don’t take everything down. My main takeaway is simple: Kubernetes solves coordination problems that don’t exist in smaller setups, and the hidden cost is operational overhead — monitoring, logging, secrets, network policies, and the organizational learning curve. Start simple with Compose, migrate only when complexity demands it. Don’t solve problems you don’t have yet.
