The Future of Kafka and Steaming
Join Jeff Mery and Josep Prat as they discuss the future of Kafka and Streaming. In this deep dive, we break down the architectural shifts and hidden "taxes" currently hitting the data streaming ecosystem—and how to engineer your way out of them. In this video, you’ll see: The "Streaming Tax" Breakdown: A transparent look at how 3x replication, inter-AZ egress, and eCKU markups are inflating your TCO by up to 500%.
The Four Factors of Production-Ready PostgreSQL
Discover how Aiven makes the 4 factors of production-ready PostgreSQL easy A database isn't production-ready just because your application can query it. To be truly ready for production, your PostgreSQL setup must be able to survive node failures, block unauthorized network access, handle sudden connection spikes without crashing, and tell you exactly why a query is running slow. Let’s explore these four factors and how Aiven puts being production-ready on easy mode.
What does the IBM acquisition of Confluent mean for the future of streaming and Kafka?
On December 8th, 2025, IBM announced a definitive agreement to acquire Confluent in a deal valued at $11 billion. It is a massive moment for our industry. The acquisition was finalized on March 17th, 2026. For some, this looks like a safe bet; a way for enterprise giants to finally "get" real-time data. But for those of us who have spent our careers in open source software and data infrastructure, it feels different. There’s a sense of wondering “when is the other shoe going to drop?”.

Say Goodbye to ZooKeeper
Automated, Zero-Downtime KRaft Migrations Now Available on Aiven The Apache Kafka ecosystem has been steadily moving toward a simpler, more scalable architecture with KRaft (Kafka Raft), leaving ZooKeeper behind. In March 2025, Kafka 4.0 dropped support for ZooKeeper entirely. Since June 2025, all new Aiven for Apache Kafka services have been deployed with KRaft by default, allowing our users to benefit from faster partition scaling and simplified cluster management.
Deterministic Simulation Testing in Diskless Apache Kafka
Aiven put Diskless Kafka through 2,200 logical hours of chaos testing using Antithesis. Here's how it held up. Testing is a necessary pillar in any software development lifecycle. At the same time, it's a fundamentally incomplete process - a cat-and-mouse game. You can't test what you can't imagine and distributed systems have a nasty habit of producing failures that no one on the team imagined.
However you Postgres, we've got you covered

Our aim is to make your use of PostgreSQL in the cloud as easy as possible, however you’re using it.
