Another important aspect of routine maintenance are cluster rebalances and expansions. If you have world-class experts running the service, the risk is not huge. Getting data into EC2 costs money, and depending on your network setup (VPC, private link, or public internet), you may need to pay both when sending and receiving data. Don’t forget that until KIP-500 is merged, Kafka is not just brokers—we need to run Apache ZooKeeper™ too, adding three or five nodes and their storage to the calculation. And what if GitHub cost me $5 a month? Make sure you account for monitoring (Kafka has many important metrics)—either with a service or self-hosted, and you’ll need a way to collect logs and search them as well. : Unveiling the next-gen event streaming platform, Project Metamorphosis Month 2: Cost-Effective Apache Kafka for Use Cases Big and Small, Unifying Streams and State: The Seamless Path to Real Time, Reducing the Total Cost of Operations for Self-Managed Apache Kafka, Measuring TCO: Apache Kafka vs. Confluent Cloud’s Managed Service, Project Metamorphosis Month 8: Complete Apache Kafka in Confluent Cloud, Project Metamorphosis Month 7: Reliable Event Streaming with Confluent Cloud and Proactive Support.
