TL;DR Aiven for OpenSearch is where you search logs from every service, with OpenSearch Dashboards included and a built-in integration for Aiven service logs. When several destinations need the same logs, or traffic bursts and mapping changes put logs at risk, put Aiven for Apache Kafka in front: applications write once, Kafka buffers and replays, and sink connectors route logs to OpenSearch, object storage and Aiven for ClickHouse.

Explore how AI coding agents can be exploited through trusted files, hooks, and MCP tools, and learn how to secure agent workflows against hidden instructions and persistent threats. Why the most dangerous instructions aren't the ones you type into the chat box For the past decade, autocomplete guessed your next line. It was helpful, annoying, or flat-out wrong, depending on the day.

The faster teams deploy, the more releases fail, and burnout climbs right with it. What 700 engineers told Harness about AI-scale delivery. Lenny's Newsletter put out its 2026 tech workforce survey this year, and you should read the whole thing. The headline stats: significant burnout jumped from 44.7% to 55.7% of tech workers in a year. Career optimism dropped from 54.8% to 48.7% over the same period of time.

As an Android developer, you’ll almost always have access to a device. However, when handling hardware, the device that you actually need often happens to be already in use, set up incorrectly, stored in another lab, or simply waiting to be reset. That’s when Android development costs start to increase.

The Australian Medicare AI agent incident highlights a broader shift in cybersecurity. AI does not need to create new vulnerabilities to increase risk. Its ability to continuously discover, test, and pursue existing weaknesses places greater emphasis on maintaining secure configurations over time, not just fixing issues once. Security teams are used to the idea that determined attackers will keep looking for a way in.

Peak traffic tests every service a purchase touches. Take these four steps before it arrives, and cover the days when your team is stretched thinnest.

A provider outage ten days before Black Friday 2025 showed how exposed peak-season revenue can be. Here’s what downtime costs, how to estimate your own number, and the questions to ask your teams before traffic arrives.

If a checkout slows down or an API call fails, why can the cause stay hidden for so long while every service dashboard looks fine? One customer click in a microservices setup may hit a gateway and a few backend services first, then a queue or a database. Every hop logs its own events, yet none of those logs points back to the original request. Distributed tracing was created to solve exactly this. Zipkin arrived early, as one of the first open-source tracers.

Why do logons crawl at one branch while headquarters is fine, or an admin group gain a member nobody approved, and no alert says a word? Trace any of those back far enough and you usually reach Active Directory. Since email, VPN, file shares and line-of-business software all lean on it for credentials, a directory fault rarely looks like itself and tends to show up as a network outage or a bug in some other application. Most of these faults creep in.

We just wrapped O11yDay London, and one theme ran through every session: writing code is no longer the hard part. Review queues, attention, operating agents in production, runaway token bills, and proving any of it is worth the money are where teams are getting stuck. The teams making progress are the ones who can see what's happening in production. Here are some highlights. We'll have videos available in the near future.
