In their own words
Aiven for Apache Kafka
Aiven for Apache Kafka is a managed Kafka service that handles provisioning, patching, backups, security, and high availability. It runs on AWS, Google Cloud, Azure, DigitalOcean, OVH, and UpCloud, with cloud availability varying by plan. Tiered storage and diskless topics can keep topic data in cloud object storage so storage and compute scale independently. A managed Schema Registry powered by the open-source Karapace project is included, alongside predictive consumer-lag monitoring, Kafka Connect compatibility, and a REST proxy. Aiven describes clusters with automatic node recovery and multi-node deployment across availability zones, and lists a 99.99% uptime SLA for Professional. Connections can use mTLS and/or SASL authentication with ACL authorization; stored data is encrypted. The Free plan costs nothing and is capped at 250 KiB/s throughput, three days of retention, and five topics with two partitions each. Developer costs $35 a month, while Professional costs $180 a month. A free 30-day trial is listed for more memory or advanced features.
Pravega
Pravega is an open-source, self-hosted storage system built around durable append-only streams for continuous, unbounded data. Streams hold parallel byte sequences, can scale as ingestion changes, and use automatic tiering to scale-out storage. Data may be retained indefinitely, allowing applications to read current and historical events. Pravega describes exactly-once delivery and processing with ordering guarantees despite client, server, or network failures, and transactions can write event sets atomically. It targets streaming applications, IoT data, and batch or interactive analytics. Connectors are listed for Apache Flink, Spark, Hadoop, Presto, Boomi, and Apache NiFi; client languages include Java, Rust, and Python. Deployment options include a single-process standalone server or distributed mode with Docker Compose. Distributed production deployments list Java 11, supported long-term storage, ZooKeeper 3.6.3, and BookKeeper 4.14.1. TLS and role-based access control are configurable.
