3 Common Pitfalls in Microservice Integration
summary
Shows concrete demos using Camunda BPM with Spring Boot, Postman and a Node.js worker to orchestrate retries, timers and compensation; one demo creates ten payment instances, job retries run every minute and a retry policy tries three times before compensating. Uses Netflix Hystrix for circuit breaking, references AWS Step Functions and Kafka alternatives, reports a user case running ~20 million processes daily and an observed 61 failed credit-card attempts recovered via compensation.
