Aiven's PG Studio is now in Early Availability, allowing you to work with your Aiven for PostgreSQL instances, directly in the Aiven Console. Over the last several decades, PostgreSQL has been steadily climbing its way to the top of popularity amongst DBAs and app developers. With the rise of AI development, PG has become the tool that you can build with at many different development stages. This starts at the home of your data, which is the Aiven for PostgreSQL service page in the Aiven Console.

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.

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.

From free hobby projects to $5/month developer setups and enterprise-scale clusters, Aiven for PostgreSQL scales with you. Find the perfect tier for your data. Our aim is to make your use of PostgreSQL in the cloud as easy as possible, however you’re using it. Whether you are just starting to learn the ropes or you're managing a global-scale enterprise database, the platform should adapt to you, not the other way around.

Inkless clusters upgrade classic topics with 90% faster recovery and 10x faster scaling with infinite storage, while adding diskless topics.

At Aiven, we use and contribute to open source to build our managed data platform. In the early days of Aiven for PostgreSQL, robust cloud-native tools for high availability and streaming backups did not exist at the level we needed. So we built our own. We created pglookout to monitor replication and handle failovers, and we built pghoard for backup and restore using object storage. These tools served us and thousands of our customers well for years. But the open-source PostgreSQL ecosystem has grown.

After reviewing all the submissions, we realised we could not have chosen just one winner. When we launched Aiven's Free Tier Kafka competition with a $5,000 prize pool, we wanted to see what the community could build. What we got back was incredible: genuine creativity, technical depth, and projects that are truly inspiring to the Apache Kafka community. After reviewing all the submissions, we realized we could not have chosen just one winner.

We are thrilled to announce that the OpenSearch major version 3 (3.3.2) is available on Aiven for OpenSearch, only a few weeks after its upstream release! The major version 3 of OpenSearch is a foundational upgrade, built on a new, high-performance core, marking a significant step forward in performance and usability. This means that as an Aiven customer, you get immediate access to a faster, more efficient search experience, all fully managed.

The Valkey JSON module implements native JSON data type support within Valkey, allowing users to efficiently store, query, and modify complex, nested JSON data structures directly. This overcomes previous architectural complexities, such as needing to serialize entire documents as strings or flatten data into hashes, by providing native handling for nested data models.
