Mystery

**Hey fellow AWS enthusiasts! ✨** This April we welcome **[Philipp Hoyer](https://www.linkedin.com/in/philipp-hoyer-621555174/)**, Lead Engineer at Rackspace Technology. He'll walk us through a journey of AWS' popular containerization services Amazon ECS and Amazon EKS running on Fargate by discussing which fits best for which use case, where EKS can make you go nuts and when ECS might shines brighter - or vice versa. **📆 Tonight's Agenda** 19:00 - Welcoming **19:15 - Talk by Phillip** 20:15 - Networking Thanks to our friends at **[CodeCam:N](https://www.codecamp-n.com/)** who open their offices for us and sponsor food and drinks for this evening. Looking forward to seeing you 👋🏻 Nora & Frank \-\-\- The talk ⤵️ **An AWS Container Journey - The Good, The Bad and The Ugly featuring ECS and EKS** EKS on Fargate promises fully managed Kubernetes with zero node management—but the reality is often more complex than expected. This talk explores the journey of building a production workload on EKS Fargate, starting with the initial motivations and architectural decisions. It uncovers three non-obvious pitfalls that only surface during real-world implementation, including challenges with load balancing, EFS integration, and logging. For each case, the underlying issues and the required workarounds are dissected to reveal the hidden operational complexity behind the “serverless” promise. Based on these insights, the talk takes a critical look at whether ECS on Fargate would have been the simpler alternative. It provides a concise overview of ECS, highlights its own limitations, and delivers a direct comparison between ECS and EKS. The session concludes with clear, experience-driven guidance on when to choose which service—helping teams avoid costly assumptions and make better architectural decisions in AWS container environments. The speaker⤵️ Philipp is a Lead Engineer at Rackspace Technology who enjoys turning complex cloud architectures into solutions that actually work in practice. He started in software development, moved through the DevOps world of pipelines, containers, and Kubernetes, and eventually specialized in AWS. He has built and operated cloud solutions ranging from big data and streaming platforms to containerized and serverless workloads. With experience in both insurance and automotive, his focus today is on real-world cloud challenges—especially the ones that don’t show up in the docs.

Speaker: **Hrvoje Novak, Anita Banjac,** **LARES - Laboratory for Renewable Energy Systems - FER** Title: **Python as a Research Workhorse: From Data to Optimal Control in Smart City Systems** Python is often seen as a glue language for automation and data analysis, but in research it becomes a powerful platform for modeling, optimization, and control. We show how it is used to build advanced decision-support and control algorithms for large-scale technical systems – starting from real-world measurements and nonlinear system models, we move through machine learning and optimization-based control, illustrating how these pieces come together in real smart city applications. We will take a behind-the-scenes look at how advanced control solutions are built, tested, and deployed in complex, real-world systems. \-\-\-\-\-\-\-\- We are in for a treat! Join us on **Tuesday** at MaMa to hear researchers from FER share their experiences from projects they did with industry partners solving real-world problems on a scale. Drinks and friendly discussion afterwards at [Old Pharmacy Pub](https://maps.app.goo.gl/AeaRdnBrMqPiRhvPA) 🍻🍷🥤☕️

\| Neki istraživački projekti trebaju prenijeti ogromne količine podataka\. Korištenje stolnog računala i uobičajene mreže možda nije najbolja opcija za postizanje optimalnih performansi\.

**Our April novel is: *The Hong Kong Widow* by Kristen Loesch** **This month’s novel blends gothic atmosphere with historical fiction and chilling horror, set against the haunting backdrop of China. The book is 368 pages in print and 10 hours and 42 minutes on audiobook.** In 1950s Hong Kong, Mei is a young refugee of the Chinese Communist revolution struggling to put her past in Shanghai behind her. When she receives a shocking invitation—to take part in a competition in one of the city's most notorious haunted houses, pitting six spirit mediums against one another in a series of six séances over six nights, until a single winner emerges—she has every reason to refuse. Except that the hostess, a former Shanghainese silent film star, is none other than the wife of the man who once destroyed Mei’s entire life. It is promised the winner will receive a fortune, but there is only one prize Mei wants: revenge. Decades later, the final night of that competition has become an infamous urban legend: The police were called to the scene of a brutal massacre but found no evidence, dismissing it as a collective hallucination. Mei knows what she saw, but now someone else is convinced they know what she did. She must uncover the truth about the last night she ever spent in that house—even if the ghosts of her past are waiting for her there. . . .

**Connected Westerville Night of Networking** *April Edition: The Introduction Economy* You've been to the networking events. You've done the small talk. Collected the cards. Forgotten the names. And walked out feeling like you just wasted two hours of your life. The problem isn't you. It's the format. Most networking events put you in a room and tell you to figure it out. So everyone defaults to elevator pitches and business talk, and nothing real gets built. Here's the truth about networking that most people miss: Your network isn't just who you know. It's who thinks of you when they're talking to someone else. *That's* The Introduction Economy. And it only works when relationships are real. There's a reason people who come once keep coming back. It starts with seven minutes that feel nothing like networking. Then we open it up. Free networking. More conversations. More momentum. This is a room full of corporate professionals, entrepreneurs, business owners, creatives, and career builders in the Westerville and Columbus area. The mix is the magic. You might never do business with everyone you meet tonight. But someone in this room will think of *you.* **By name**. So, the next time someone needs exactly what you do, you get the recommendation. **April 14th. RSVP now.** **When:** Tuesday\, April 14th \| 6:15 PM \-\- 8:00 PM **Where:** Vineyard Community Center \| 6000 Cooper Rd\, Westerville\, OH 43081

The topic for April is "Water" Speak Easy: true stories, told live. The idea is simple: an audience, an open microphone, and great stories. Hilarious, gripping, poignant- it's up to you. Audiences are invited to come to listen or come to tell as folks from all corners of Columbus offer their stories live on stage! Held at Wild Goose Creative's warm, intimate space, this night of tales occurs on the 3rd Thursday of every month. Doors open at 6:30 pm, show starts at 7:00 pm. Please arrive early if you want to tell, as we generally only have room for a limited number of tellers, and the sign-up sheet has a tendency to fill up fast. Formed around the idea that people need stories--they're what hold and draw us together--SpeakEasy celebrates the strangeness and commonness of being human. And in a world of smartphones, Facebook, Twitter, and more . . . it gives people a real, breathing, in-person way to connect. The night is geared for true stories of all kinds, taking the best tales told around kitchen tables, in darkened pubs, on the street corner, and at late-night parties and giving them an audience. Speak Easy is also a great outlet for performers, writers, and artists looking to share their favorite stories and perfect their skills. We strongly encourage tellers to please tell the story rather than read it so we keep within the spirit of good storytelling and stay engaged with the audience. All are welcome. Hang around after the show for a drink and build community!
