Meet AURA: The Open-Source Agent Harness for Production AI : Autonomous Incident Response Demo

Watch AURA autonomously respond to a production incident in real time—from building its reasoning context and querying PagerDuty and ClickHouse, to triggering a human-in-the-loop approval with the on-call SRE, to removing the stuck pod and validating remediation. Every behavior is defined in a simple config. AURA is Mezmo's AI-powered incident response agent built for platform engineers and SREs managing high-volume telemetry pipelines.

The Modern Messaging Primer: Navigating the Shift from Legacy Middleware to Open Source Innovation

The shift from legacy middleware to open-source innovation promises agility and cost savings, but introduces the 'Modernization Tax'—operational complexity that requires new approaches to observability, governance, and management across hybrid messaging environments.

Icinga as Open-Source MSP Monitoring Software: Multi-Tenant Monitoring for IT Service Providers

If you run a managed service provider, your RMM software is the backbone of daily operations. Remote management, patch cycles, ticketing workflows – it handles the essentials. But if you’re monitoring more than a few dozen client environments, you’ve likely noticed that monitoring and management are not the same thing. And that difference matters more the larger you grow. This post is not about replacing your RMM.

Get Kafka-Nated S2E4: Debugging the Kafka-Iceberg Connector

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.

Open Source Cloud Cost Management Tools: OpenCost, Kubecost, and More

Open source software is an essential component of business operations. According to Harvard Business School, 96% of commercial software includes open source code. If companies were to build these tools from scratch, it would cost an estimated $8.8 trillion — roughly 3.5 times what companies currently spend on software. That’s not great for the bottom line. Many open source solutions are also available as standalone tools. Consider Kubernetes.
