A server, a monolith, Postgres, maybe a load balancer in front. For most products that was the entire architecture, and it held.</p> <p>Now the same conversation opens with API gateways and doesn&rsquo;t stop: Kubernetes, service meshes, Kafka, Redis, three databases because each one is good at one thing, gRPC, GraphQL, Elasticsearch, Terraform, Prometheus, tracing, sharding, replication, autoscaling.</p> <p>The awkward part is that none of it is junk. Every one of those tools exists because someone hit a real wall: more users, more data, more teams, more regions, more nines of uptime.</p>
