Case Study: JobCloud achieves event-driven modernization and zero-downtime Kafka operations with Aiven for Apache Kafka

JobCloud builds event-driven architecture with Aiven

JobCloud, owner of Switzerland’s largest job boards, faced a tangle of legacy systems and wanted to modernize to an event-driven architecture without directly touching strange APIs. After evaluating streaming options and choosing Apache Kafka for its ecosystem and connectors, JobCloud selected Aiven and its managed Aiven for Apache Kafka service to avoid the heavy operational burden of running Kafka themselves.

Aiven delivered a fully managed Kafka platform that acts as a message bus between JobCloud’s disparate systems, with integrations into Grafana/Prometheus and Slack for monitoring and alerts. The result: minimal operational overhead, seamless scaling over the past three years, and virtually no interruptions—“we’ve never had any problems with Aiven”—with the team rarely noticing Kafka is running and only a single, quickly resolved support case.
