We recently announced the Limited Availability (LA) launch of Aiven Apps, which lets teams define, run, and scale production-ready, real-time applications using container and Compose-based workflows they already know. It provides a managed, stateless runtime that runs directly inside your data perimeter, letting you deploy applications alongside open-source data services like PostgreSQL and Apache Kafka.

Many businesses see emissions reduction as a cost sink: assigning people, maintaining compliance, the hard labor of calculating carbon signatures. That view is out of date – and a new partnership between Aiven and data provider OxygenIT demonstrates why. Our premise: your carbon footprint isn't just about understanding emissions; it's about understanding your business. Today, we're announcing a new service that helps with both.

In the high-stakes world of Online Travel Agencies (OTAs) like Expedia, Hopper, Priceline, and Airbnb, seconds matter. A traveler searching for a "beachfront stay in Hawaii" isn't just looking for a room — they are reacting to weather changes, fluctuating flight prices, and social media trends. Traditional travel platforms often rely on stale data: yesterday's search history or last week's preferences. To truly compete, travel platforms must pivot to Real-Time Context Engineering.

Luckily, in Kafka cache invalidation is not an issue, but we still need to name things. Let me tell you a story about naming things in Kafka.

Half a year ago, we launched a free tier cloud Kafka. We have 16,808 clusters so we got curious: what are these builders telling us about the state of Apache Kafka? The headlines this quarter suggest Kafka is dying because the streaming market is consolidating. At Aiven we see the opposite. Kafka is not shrinking. It is spreading outward from enterprise platform teams into the hands of individual builders. We are now seeing >200 new Kafka clusters created per day on the free tier.

When we launched the Free Tier, we made a promise: graduating to a paid tier shouldn’t feel like switching platforms. It should simply feel like tapping “Continue watching in HD”. The Developer Tier for Aiven for Apache Kafka is that upgrade. $35 a month for the serious, ongoing workloads that haven’t yet reached enterprise scale. Everything we said was coming is now live.

Discover Aiven for DataHub: a fully managed, open-source data catalog that gives your teams and AI agents the context they need to find and understand data. According to an MIT study, 95% of AI projects fail to deliver value. I've been thinking about why that number is so stubbornly high, and I've come to believe the answer isn't about models,compute or even data quality in the traditional sense -It's about context.

One space character, one broken backup. See how Aiven’s engineering team traced an OpenSearch k-NN bug to its source and implemented a lasting fix. Backing up your OpenSearch indexes via the Snapshot process is vital for disaster recovery, allowing you to restore the indexed data, cluster configuration and state if something goes wrong.

Unify your code and data. Aiven Apps lets teams deliver real-time applications faster, without building new platforms. No lock-in. No custom pipelines. No egress surprises. We are excited to announce the Limited Availability (LA) launch of Aiven Apps! For over a decade, Aiven has simplified how you store and stream data with an open-source foundation. Over that same time, data volumes have exploded, and so has the friction caused by the distance between where your data is stored and where your code runs.

In this episode of Get Kafka-Nated, host Hugh Evans is joined by Stanislav Kozlovski, Apache Kafka committer, independent consultant, and author of 2 Minute Streaming — a newsletter with over 7,000 subscribers. After six years at Confluent, including time on the Kafka Serverless team, Stan went independent and has been writing and consulting full-time. He's one of the most recognised voices in the Kafka community, with over 50k followers across social media. In this session we go somewhere the streaming industry rarely goes honestly: Kafka costs.

In this episode of Get Kafka-Nated, host Hugh is joined by Anatolii Popov, Senior Software Engineer at Aiven, to dive into one of the most talked-about integrations in the modern data stack: Kafka to Apache Iceberg. Anatolii was accepted to speak at Iceberg Summit 2026 on debugging the Kafka Connect Iceberg Connector, and in this session we’ll cover the talk he would have given, including common failure modes, debugging locally, catalog complexities, and where the integration is heading next.

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%.

March 11th, 4PM GMT Yingjun Wu is the founder and CEO of RisingWave Labs, a company building a distributed SQL database for stream processing, with over a decade of experience spanning academic research and large-scale production systems. In this episode we'll be sitting down for a coffee and a conversation with Yingjun's about what a streaming database actually is, how message brokers and streaming databases fit together in real-world architectures, and what his journey from database researcher to founder has taught him.

In Episode 3 of Elephant in the Room, we move from discussion to delivery with a hands-on, live build of a real, community-focused application. Join Jay Miller, Abigail Mesrenyame Dogbe and Andres Pineda as they collaboratively design and build a CFP (Call for Proposals) review platform using PostgreSQL and Django. The aim: create a practical tool that helps speakers receive better feedback and helps organisers discover new and diverse voices.

Tired of not knowing why your home lab containers are crashing? In this video, we’ll walk through how to set up a consolidated logging pipeline using Aiven for PostgreSQL (with TimescaleDB), Fluentd and Grafana — all running on my upgraded Mac Mini home lab. The key insight: never keep your troubleshooting tools on the same machine that's giving you problems!

In this episode, we sit down with Viktor Kessler, co-founder of Vakamo, major contributor to Lakekeeper, and organiser of Apache Iceberg Meetup Europe, to explore the evolving world of Apache Iceberg. From architectural deep dives to open-source governance, Viktor shares insights from building an Iceberg REST catalog in Rust, launching a company around open data governance and growing the European Iceberg community from Dublin to Vilnius.

In Episode 4 of Elephant in the Room, we tackle a question many teams struggle with: how do you protect sensitive customer data from your own developers while still running and improving your web application? Join Jay Miller (Aiven) and Tim Schilling of Djangonaut Space as they explore a real-world privacy challenge. Djangonaut Space’s application process requires collecting personal information from applicants, but reviewers and contributors should not have access to identifying details. The goal: enable fair review and active development without exposing sensitive data.
