**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.

\| Neki istraživački projekti trebaju prenijeti ogromne količine podataka\. Korištenje stolnog računala i uobičajene mreže možda nije najbolja opcija za postizanje optimalnih performansi\. Postavljanje DTN čvora nije uvijek jednostavno: postoji više vrsta softvera\, određene parametre na poslužiteljima treba prilagoditi\, a udaljenosti dodatno smanjuju performanse TCP‑a\. Projekt GN4‑3, u sklopu aktivnosti WP6 T2, proveo je niz testova koristeći GÉANT Testbed Service (GTS). Rezultati su objavljeni u matrici, a dokumentacija i skripte za postavljanje čvorova u dockeriziranom okruženju dostupni su na DTN wiki stranici (https://wiki.geant.org/display/DTN). ## About Network engineer (CCNA, CCNP). My research interests are in the field of secure network communication, implementation of new network protocols and WANs technology (L2 MPLS, multicast, GMPLS, SDN...).

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) 🍻🍷🥤☕️
