Episode notes
Message Bus Fundamentals
- Modern message buses enable durable and reliable distributed applications.
- They facilitate asynchronous communication and decoupled architectures using brokers like RabbitMQ.
ATM Analogy
- ATMs exemplify asynchronous, durable transactions.
- They store withdrawal records and process them later, ensuring functionality even during outages.
Message Brokers vs. Event Streaming
- Message brokers use queues and message locking.
- Event streaming systems like Kafka are partitioned log files, offering replayability but different semantics.
