Enterprise Messaging with Apache Pulsar

Challenge

The client needed to consolidate a heterogeneous messaging landscape (Tibco Rendezvous, Kafka, ArtemisJMS) into a future-ready platform that is geo-redundant, highly available, and scalable, while staying open for future integrations.

Approach

I designed and implemented a multi-layer enterprise messaging platform based on Apache Pulsar, combining operational safety, automation, and governance:

• Cluster design with geo-redundancy and failover strategy
• Protocol support for Pulsar-native, Kafka interop, MQTT, and AMQP
• Governance model with tenants, namespaces, RBAC, and encryption
• Declarative object management via custom Ansible modules
• Evaluation of commercial offerings under digital-sovereignty criteria
• Custom tooling for health checks, data pumps, self-fencing, and load testing
• End-to-end observability in Prometheus/Grafana

Snapshot

• Industry: Industrial enterprise
• Time frame: 2024-2025
• Technologies
  • Apache Pulsar
  • Golang (custom tools and data pumps)
  • Kubernetes / bare metal
  • Prometheus / Grafana stack
  • Ansible (custom Pulsar modules)
  • TLS, JWT, RBAC

The platform delivers stable, high-throughput data streams and serves as a central integration layer for business-critical systems.
