STATELESS vs STATEFULL SERVERS At its core, the client–server model is simple. Clients initiate requests, servers process those requests and return responses. But the real design complexity begins when you ask a seemingly small question: where does state live? In stateless systems, the server does not retain any client-specific information between requests. Every request must carry all the data required for processing. This makes scaling significantly easier, because any request can be handled by any server instance. It also explains why stateless systems lean heavily on cryptography, such as signed tokens and JWTs, to establish trust and identity without server-side memory.
