You probably do not need Kubernetes

Many developers unnecessarily adopt complex tools for small projects. For RAG chatbots with limited content, a vector database is often redundant because the system can simply paste matching pages into the prompt. Similarly, Kubernetes is designed for managing numerous services across multiple machines with independent teams. For small apps with few users, a single VPS is more efficient. Avoiding these over-engineered solutions reduces monthly costs and eliminates unnecessary technical complexity during early development stages.
