Microservices in action at the DutchNationalPolice
summary
Private OpenStack cloud runs about 500 servers with roughly 24 PB storage and serves ~65,000 users; a 30-person product line builds ~50–100 Spring Boot services (Java, Kotlin/Scala experiments), Angular/TypeScript front ends, Kafka streams, Cassandra/Mongo/MySQL backs, Ceph storage and Consul + SSE client-side discovery with Ribbon for service calls. CI uses GitLab, Jenkins pipelines, Terraform/Ansible, Nomad scheduler; mutation testing (PITest), Gatling twice daily, Graylog/Zipkin/Grafana for ops; deployment is zero-downtime and works, but frontend monolith, auth LDAP scaling and shared-code coupling remain challenges.
