Frameworks Unplugged: Building Distributed Systems in Pure Java
summary
Shows how to build a simple session‑replicated cluster in pure Java using the JDK HttpServer, sockets and a ConcurrentHashMap and demonstrates JDK HttpServer for endpoints, multicast discovery for peer detection, and byte serialization tradeoffs. Implements queues, executor pools and point‑to‑point TCP for replication, explains why Java serialization breaks across versions, demonstrates vector clocks and last‑write‑wins conflict resolution, and shows a working demo while warning about lost updates and scaling limits.
