Join us for an Apache Kafka® x Apache Flink® meetup on Wednesday February 25th from 6:00pm in Dublin hosted by Autodesk! **Venue:** Autodesk 1 Windmill Lane, 2nd Floor, Dublin D02 F206 **PLEASE BRING A FORM OF VALID ID AND REGISTER WITH YOUR DETAILS FOR SECURITY PURPOSES/BUILDING ACCESS. THANK YOU!** **Agenda:** * 6:00pm: Doors open * 6:00pm – 6:30pm: Food, Drinks & Networking * 6:30pm - 7:15pm: John Byrne, Sr. Manager, Partner Applied Solutions, Confluent * 7:15pm - 8:00pm: Rishayah Kumar Trivedi, Senior DevOps/SRE Engineer, Autodesk & Douglas Hobson, Principal DevOps/SRE Engineer, Autodesk * 8:00pm - 9:00pm: Additional Q&A and Networking **First Speaker:** John Byrne, Sr. Manager, Partner Applied Solutions, Confluent **Title of Talk:** Flink State: Design Choices You Can’t Undo *(on Confluent Cloud)* **Abstract:** A practical look at how state behaves when running Flink on Confluent Cloud, the early design decisions teams often underestimate (keyed state, TTLs, upgrades, reprocessing), and the kinds of problems that only show up months later. **Bio:** John Byrne is a Sr. Manager, Partner Applied Solutions at Confluent, the company founded by the original creators of Apache Kafka®. With a strong background in data engineering, John previously worked for Slice, Registers of Scotland, and Sopra Steria, where he specialized in event streaming, ETLs, and data governance. Passionate about GIS, mapping, and ETL processes, he has delivered talks at FOSS4G and developed production-grade ETL projects incorporating spatial data and mapping technologies. In his spare time, John enjoys playing golf and coaching his local youth rugby team. **Second Speakers:** Rishayah Kumar Trivedi, Senior DevOps/SRE Engineer, Autodesk & Douglas Hobson, Principal DevOps/SRE Engineer, Autodesk **Title of Talk:** To Production and Platform: Our Kafka Journey, DR Strategy, and Kafka-as-a-Service **Abstract:** In various organisations, multiple teams have historically had to build Kafka the hard way, spending months on security hardening, compliance validation, observability, and disaster recovery, often repeating the same work with inconsistent outcomes. The result is slow onboarding, duplicated effort, and operational silos that don’t scale as more streaming use cases come online. In this talk, we walk through our Kafka production journey on AWS MSK: how we began with a POC, what it really takes to make Kafka production-ready, and the key platform decisions we had to take to standardise the architecture and operations. We’ll then dive into disaster recovery for streaming applications where the hard problems aren’t just infrastructure failover, but event continuity and restoring pipelines under pressure. We’ll share our HA DR approach for Kafka-backed systems, including an active/passive regional strategy, and practical failover/failback considerations to minimise RPO/RTO. Finally, we’ll close with our Kafka-as-a-Service (KaaS) vision for Autodesk teams: self-service, policy-driven deployments and service tiers that let internal teams onboard in hours instead of months so the product teams can focus on building streaming features, while the platform provides consistent guardrails for security, reliability, and recoverability. Attendees will leave with a checklist of production-ready requirements for Kafka, a clear mental model for DR in streaming systems and a set of platform patterns for evolving towards Kafka-as-a-Service. **Bios:** **Rishayah Kumar Trivedi (Senior DevOps/SRE Engineer, Autodesk)** Rishayah is a Senior DevOps/SRE engineer at Autodesk's data streaming and processing platform team with 9+ years of experience building scalable cloud infrastructure and automating enterprise deployments. He holds industry-recognised credentials in AWS, Kubernetes, and DevOps, and has led many initiatives improving reliability, performance, and security through Shift-left approach, IaC and CI/CD best practices. **Douglas Hobson (Principal DevOps/SRE Engineer, Autodesk)** Douglas is an accomplished Principal Devops/SRE engineer in Autodesk's data streaming and processing platform team with extensive experience in cloud architecture, infrastructure automation, and systems reliability. With a proven track record at various firms, he has led global teams in building scalable, secure, and high-performing cloud environments.

**Overview** === He's back! For our February event, we are thrilled to welcome a special guest out of semi-retirement: John Ryan. As a former Snowflake employee and current Data Superhero, John has been there since the beginning. In fact, he and I co-hosted Ireland’s first-ever Snowflake event. Since the venue was a converted church, we called it the **"Church of Data."** It was the perfect setting to kick off our Snowflake evangelism. **Abstract** === Moving from on-premises data platforms to cloud isn’t just a technology change — it’s a cost and operating model shift. Many teams underestimate this and end up with performance issues, spiralling spend, or both. This session explains why traditional on-prem thinking breaks down in Snowflake, how Snowflake is designed to scale, and where customers commonly go wrong. Using real lessons from three large Snowflake customers, we’ll walk through: What “scale up” really means in Snowflake (and when not to use it) Three common mistakes that quietly drive cost and poor performance What actually worked in production — not theory, not marketing slides This is a practical, experience-based session aimed at engineers, architects, and technical leaders who want Snowflake to run faster without wasting money.

***Mountain Skills for Only €120 / course*** Ever wanted to learn the skills you need to become a competent navigator in the Irish mountains, the UK, the Alps or beyond! As a fully qualified mountain guide and course provider for Mountaineering Ireland and the UK, I run Mountain Skills which is a nationally accredited course and is delivered in an upland environment. Hiking in Ireland can be challenging not only because of its wilderness, but the island has very little sign posted hiking trails in the mountains or hills. In addition to this, as being an island in the Atlantic we experience the forces of nature; storms and weather events. In other words, Ireland is probably the best place in Europe to learn a new outdoor skill like Mountain Skills. The aim of this course is to help you learn the skills you need to get out hiking in the hills and mountains independently, safely and responsibly. You will learn how to navigate with confidence by any type of weather conditions. A Mountain Skills course is run over 2 days in an upland environment and covers: Map reading, map description, map scale, contour lines, land and ground features, navigation legs, simple navigation techniques, setting the map, the 5 D, estimation of direction & destination, grid reference, mountain hazards, hypothermia, mountain environment, timing, pacing, route planning, route card, emergency procedures, personal equipment, safe movement skills, river crossing and much more… Some level of fitness is essential in taking part in this course. Each course (MS1 / MS2) is a 20 hour syllabus which includes indoor and outdoor sessions and night navigation (MS2) **A course includes:** Maps and compass provided, tea breaks, course notes, 3 route cards, a free hiking day practice as part of a weekend. **For Only €100 for under 18 and students and €120 for adults.** Accommodations can be provided Feb 21-22 MS1 Comeragh, Co.Waterford Feb 26/March 01 - MS2 in Glenmalure, Co.Wicklow March 21-22 MS1 Glenmalure, Co.Wicklow March 28-29 MS2 Glenmalure, Co.Wicklow April 09-10 MS1 Glenmalure, Co.

The next Dub\|Sec meetup will take place in the Dublin Workday offices on February 25\, 2026\. Workday are delighted to be hosting this Infosec event in conjunction with Dub\|Sec and the Women in Cybersecurity Community Association \(WICCA\)\. In order to ensure your place on the evening, please sign up through [this link](https://invites.envoy.com/group-invite/TQWwzJ2WyL5lED4D). We'll be there from 6.00pm. Our first speaker will start at around 7pm. **19:00 - Building a digital beehive: The cluster that wasn't real, but the attacks were** by Arnav Tripathy Kubernetes is everywhere now—and so are attacks against it. Misconfigurations, exposed APIs, and overly permissive RBAC have made clusters a prime target, while most security tools stop at scanning images and YAML instead of showing what attackers do after they get in. This talk introduces KubeDecoy – a lightweight, open-source Kubernetes honeypot built from familiar components: vcluster, Falco, Falcosidekick, and NGINX. The goal is simple: stand up a convincing fake cluster, expose realistic attack surfaces, and quietly observe how real adversaries interact with them. **19:40 - OffSec x AI : The Rise of Autonomous Pen-testing Agents** by Manav Bankatwala. As we are witnessing a shift from static security scanners to "Agentic AI", tools that don't just find signatures, but actively reason, plan, and exploit like a human hacker. This talk will explore the current state of AI in offensive security, using the open-source tool Strix as a live case study. If you would like to speak at any future Dub\|Sec\, please email us at [info@dubsec.ie](http://info@dubsec.ie/)! Join us for some drinks, food and general chat about infosec. Everyone is welcome whether you’re a pro, an amateur or just curious about the field!

Join us for this Thursday evening cycle on the southside of the city up to the Killakee viewpoint and back. It’s a decent climb and offers some great views over the city. Warning: this cycle has a steep/long climb. Back and front lights on your bike are essential for this cycle. The total distance is 25km, and so not far but it has 350m of climbing taken on all at once. For perspective, 350m is about twice the amount of climbing as the Thursday Howth cycle. If you are unsure of your ability to do this, I recommend trying the Thursday Howth Cycle first. We do not go fast up the climb, we go as slow as needed. Here is our plan for the evening: 1️⃣We leave at 6:30PM from Portobello Harbour 2️⃣We cycle south through Rathfarham and climb up to Killakee via Stocking Lane 3️⃣ We'll head back to starting point via Cruagh Road. 4️⃣ If time allows, we'll make a stop at The Merry Ploughboy pub for a break and refreshment before heading back to the start.

Dublin Dataviz is delighted to welcome Andy Kirk as our first speaker of 2026! Andy is the founder of [Visualising Data](https://visualisingdata.com/) and works with [clients around the world](https://visualisingdata.com/clients) as a data visualisation design consultant and prolific [trainer](https://www.visualisingdata.com/training/). He is a a four-times published [author](https://www.visualisingdata.com/book/) and host of the ‘[Explore Explain](https://www.visualisingdata.com/podcast/)’ video and podcast series. In his talk, **The 7 Hats of Data Visualisation (Revisited!),** Andy will showcase the value and richness of data visualisation as a key literacy in this contemporary digital age. We all have a stake in this, whether that is through our roles as creators, consumers or coordinators, but it can appear to be a substantial challenge to fully embrace the multi-disciplinarity of this subject, whether as individuals or more generally across organisations. Framed as the ‘7 hats’ of data visualisation, Andy will look back over his 15+ years of experience developing an expertise in this subject to present his view of the major competency ‘ingredients' that make up the all-round talent recipe of a visualiser today. He will differentiate the knowledge required from skills necessary to demonstrate, the attitudinal maturity from the technical intelligence. He will also advise on some of the strategies that will help you continue to develop and refine your data visualisation literacy. Join us for what's going to be an amazing evening, with pints in Arthurs pub surely to follow.

We present a hands-on Demo from the Google Cloud Professional Architecture Exam Learning Path Location: 1 O'Connell Street Lower, North City, Dublin, D01 TX31

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer. Thanks to our 2026 sponsors: [Clarivoy](https://www.clarivoy.com), [What Box Consulting Group](https://www.whatboxconsultinggroup.com), [Conductrics](https://www.conductrics.com), and [Piwik PRO](https://piwik.pro) More info at [cbusdaw.com](https://cbusdaw.com)

Join us at Losing Weight in Columbus at Bloc Garten on a Saturday afternoon. This will be an active and engaging day, in lieu of our weekly check in. Why climbing you may ask? Because that's what I know best, and also since its and indoor sport, its great for a winter time hobby! Join us and find out what it's all about! We'll also do a brief check in to see how everyone is doing. Day passes cost 23$ + 7$ shoe rental fee for a total of 30$ [https://5.life/bg/](https://5.life/bg/)
