Hi folks! Welcome to our June Cloud Native London meetup! Join us to hear from our two fantastic speakers and network with your fellow techies over pizza and drinks, or alternatively chat and following along on Youtube or LinkedIn! 6:00 Pizza and drinks 6:30 Welcome 6:45 Universal Mesh: Connect and Secure Everything (Mark Boddington, HAProxy Technologies) 7:15 Building Abstractions That Matter: A Developer Platform on Kubernetes (Chaamini Mangaleswaran, WSO2) 7:45 Wrap up See you there! Cheryl (@oicheryl) **Universal Mesh: Connect and Secure Everything (Mark Boddington, HAProxy Technologies)** Managing connectivity across diverse business units, clouds, locations, and partners is a complex challenge for large organizations. Traditional solutions like VPNs and firewalls provide network-level connectivity, while Service Mesh offers application-aware traffic management for cloud-native environments – but there’s a huge difference in how these connectivity models are managed, secured, and observed. Universal Mesh bridges this gap with a unified interconnectivity model – delivering the benefits of Service Mesh in a resource-efficient model that works across your entire infrastructure. Universal Mesh brings together North-South and East-West communication in a consistent pattern to connect every cloud, app, and service. Join us to discover how Universal Mesh simplifies connectivity management, unifies security and governance, and provides consistent control over traffic flows—regardless of where your applications run or how they’re built. *Mark began his career at the close of the last millennium, working as a "pimply faced youth" (PFY) managing mini-computers (not Raspberry Pis) and 'windoze boxen' for a local brick company. He eventually specialized in Unix Systems Administration and joined NetBanx, a Silicon Fen company, where he managed and secured the application infrastructure for one of the very first payment gateway operators.* *In 2006, Mark leveraged his Unix and Networking expertise in a post-sales role at Zeus Technology, a web-server and software Load Balancer vendor. Six months later, he transitioned to pre-sales. He is currently at HAProxy - the world's fastest and most widely used software load balancer - essentially doing the same thing (but with a dash more kubernetes).* *Connect on Linkedin: [https://www.linkedin.com/in/mark-boddington](https://www.linkedin.com/in/mark-boddington)* **Building Abstractions That Matter: A Developer Platform on Kubernetes (Chaamini Mangaleswaran, WSO2)** Kubernetes provides powerful building blocks, but turning those blocks into a usable developer platform is hard. Many platform teams end up assembling CI pipelines, deployment tools, portals, and monitoring systems, only to pass the resulting complexity on to developers.In this talk, I’ll share the thinking behind OpenChoreo, an open-source, modular platform designed to sit on top of Kubernetes and make it easier for developers to build and run software without needing to understand everything underneath. The key idea is simple: introduce the right abstractions, so developers can focus on shipping features while platform teams retain control and consistency.In this talk we will discuss practical examples of what to hide, what to expose, and how to avoid turning Kubernetes itself into a developer-facing interface. If you’re building or struggling with an internal developer platform, this talk is for you. *Check out [https://www.oicheryl.com/cloudnativelondon](https://www.oicheryl.com/cloudnativelondon) if you're interested in speaking or sponsoring.*

**We're back at Salisbury House for our summer London Airflow Meetup! Join fellow members of the data engineering community for an evening of engaging talks, great food and drinks, and exclusive swag!** **PRESENTATIONS** ***Talk #1: The Orchestration Layer: A Blueprint for Scaling Dynamic DAGs with Integrated Data Quality Gates*** * **Speaker**: [Vasudev Maduri](https://www.linkedin.com/in/vasudevmaduri/), Staff Data Engineer, Admiral Group Plc Ensuring high-quality data, accuracy, completeness, and schema validity is essential for building data trust. However, scaling data quality checks across diverse datasets often leads to duplicated boilerplate Python code, human error, and a massive bottleneck for Data Engineering teams. In this talk, we’ll explore how to shift data quality from a backlog of tech debt into an automated, self-serve developer experience directly tied to Airflow. We will demonstrate how to build a multi-faceted data observability framework that empowers end-user teams to define their own DQ rules without writing any Python code. By hiding complex Airflow code, users simply select their parameters—YAML configurations that instantly translate into fully dynamic, end-to-end DAGs, including in-flight data quality gates. The core of this session focuses on the technical implementation of integrated DQ checks that live directly *inside* the generated pipelines. You’ll learn how this metadata-driven approach enables a "shift-left" strategy for data observability, automatically enforcing data contracts and routing alerts without manual engineering intervention. ***Talk #2: Self-healing Data Pipelines in Airflow*** * **Speaker**: [Nilesh Khandalkar](https://www.linkedin.com/in/nileshskhandalkar/), Senior Manager, Capgemini Modern data pipelines remain largely reactive—failures trigger alerts, manual retries, and ongoing operational overhead for engineering teams. As systems scale, this approach introduces fragility, delays, and growing complexity in maintaining reliable workflows. This session explores how to design self-healing data pipelines in Airflow using practical patterns such as intelligent retries, conditional branching, and targeted recovery mechanisms. Real-world failure scenarios are used to illustrate how pipelines can detect issues, trigger remediation steps, and resume execution without full restarts or human intervention. The session also looks ahead to how AI-assisted anomaly detection can further enhance these systems by identifying unexpected patterns and enabling more proactive, resilient data workflows. ***Talk #3: What We Got Right (and Wrong) Building a 50-Source Data Platform on Airflow*** * **Speaker**: [Arnaud Caldow](https://www.linkedin.com/in/arnaud-caldow-384423142/), Senior Data Engineer at Collibra Collibra helps enterprises govern their data, but how does Collibra's own data team manage the data that powers the business? The answer is an Airflow-based platform that stitches together dlt, dbt, Kubernetes and Collibra's own product for governance -- all orchestrated through 87 DAGs serving 12 business domains. This talk traces a data point's journey through the stack: from API extraction via dlt pipelines running inside KubernetesPodOperator pods, through a layered dbt architecture where platform engineers standardize data and analysts build business models on top, into analytics outputs that serve multiple business teams, and finally back into Collibra Data Governance via reverse-ETL integration DAGs. Along the way, I'll share the patterns that emerged from operating this at scale: how we evolved from one-off custom pipelines to a reproducible framework that's documented well enough for AI subagents (or a new hire) to generate models from scratch, how our own Pod Operators let us test feature branches on shared environments, and how we're leveraging that same mechanism to migrate from Redshift to BigQuery (and from Airflow 2 to Airflow 3) without downtime. Behind the scenes, a 1Password-backed pipeline diffs credential hashes nightly, catching rotations before they break a DAG. **AGENDA** * **5:30-6 PM:** Arrivals, networking, food & drinks * **6-7:45PM:** Presentations * **7:45-8PM:** Networking

We start June by reading Amanda Montell's 2019 effort, *Wordslut: A Feminist Guide to Taking Back the English Language*. Our first non-fiction of 2026 is a 'brash, enlightening, and wildly entertaining work of pop linguistics and a feminist look at gendered language and the way it shapes us.' (Book jacket) '[Montell], reporter and feminist linguist, deconstructs language—from insults, cursing, gossip, and catcalling to grammar and pronunciation patterns—to reveal the ways it has been used for centuries to keep women and other marginalized genders from power.' -Waterstones https://www.goodreads.com/book/show/53066379-wordslut In the eternal hope of good weather in London in the spring/summer, we will have the meeting in Haz St Paul's lovely outdoor area. So come along for some great atmosphere, delicious Turkish food, and insightful discussion. N.B. We will be charging an event fee of £3, non-refundable, to discourage no-shows and contribute to the running costs of the group. Please only sign up if you intend to come along as space is limited to make for an effective discussion!

We are bringing Microsoft Build sessions to Columbus Ohio! The Central Ohio Azure Meetup and Central Ohio .NET Developer's Group (CONDG) are coming together to bring some of the labs and breakouts from Microsoft Build to your backyard. In this free, 1 day event, you are going to Build stuff with us! And yes, there will be free food. So please RSVP for a head count!

We've moved to guild.host Look for us there. https://guild.host/events/buckeye-cocoaheads-nscoders-tcbrk5

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

*Note: this is a demonstration event only, you **will not** shoot you own images. However, if you bring your camera we can test it for compatibility with the studio lights.* Bondage elements can add an extra layer of emotion and artistry to your images. Sample images on the internet are however dominated by BDSM style shots that are often sexualized and emphasize the model being in distress. In this demonstration Rachel and I show ways to use bondage elements in an artistic way. We explore the types of accessories that work best in artistic images and the best way to photograph them. Our model is Rachel Adams, an internationally known fetish model with many years of experience in this genre.

**Latest Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for speakers for our Monthly Meetups!
