What Aiven for Apache Kafka is
Aiven for Apache Kafka is a managed Apache Kafka service that handles provisioning, patching, backups, security, and high availability. It runs on AWS, Google Cloud, Azure, DigitalOcean, OVH, and UpCloud, though available clouds depend on the plan. Tiered storage and diskless topics can keep topic data in cloud object storage, allowing storage and compute to scale separately. The service includes a managed Schema Registry, Kafka Connect compatibility, a REST proxy, and predictive consumer-lag monitoring. Aiven describes its clusters as self-healing, with automatic node recovery and deployment across availability zones. Connections can use mTLS or SASL authentication with ACL authorization, and stored data is encrypted. The Free plan costs nothing and includes 250 KiB/s throughput, three days of retention, and five topics with two partitions each. Developer costs $35 a month; Professional costs $180 a month and lists unlimited throughput, connections, partitions, and retention. A free 30-day trial is available for more memory or advanced features.
