**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. Get in contact with Philipp on [LinkedIn](https://www.linkedin.com/in/philipp-hoyer-621555174/) \-\-\- **Please note:** At the event, photos and videos will be taken for marketing purposes both by our hosts and our location sponsors. We try to offer a hybrid experience by providing a video stream of the talk. There will be no recording published after the event. Please also keep in mind, that we try our best effort to provide a good streaming experience. We don't offer a professional stream, so delays, technical issues or other interference are a matter to be tolerated.

Most developers never see the switch happen. In this talk, we'll explore how mutex work under the hood and how the runtime decides which face to show. Through a series of benchmarks, we'll observe mutex behavior under increasing contention and across different core counts to see both modes in action. 9:05 PM: Networking Networking over drinks and food *** Hosted By Natalie Pistunovich, Organizer Ole Bulbuk, Organizer Tim Scheuermann, Organizer Anderson Queiroz, Organizer Complete your event RSVP here: https://gdg.community.dev/events/details/google-gdg-berlin-golang-presents-hybrid-april-golang-meetup-2/.

Tatry IT Ťa pozýva na pravidelné stretnutie o aktuálnych a zaujímavých (nie len) digitálnych a IT témach. Eventy organizujeme v spolupráci s [Coworking Poprad](https://coworkingpoprad.sk). Príď na meetup Tatry IT Community na tému Salesforce. Salesforce si veľa ľudí spája najmä s obchodom, no v praxi ide o oveľa širšiu platformu. V tejto prezentácii ukážem, čo Salesforce vlastne je, kde sa používa, aké typy procesov na ňom firmy stavajú a prečo je zaujímavý aj pre ľudí mimo Salesforce sveta. Pridám aj svoj vlastný príbeh, krátky pohľad do prostredia Tourlane a na záver spomeniem aj nonprofit oblasť, kde Salesforce ponúka oprávneným organizáciám licencie zdarma. \ **Speaker: Karol** Zaregistruj sa [tu](https://docs.google.com/forms/d/e/1FAIpQLSdZALAk-Kau7oEudSai555Ut7vDRroJlB1WqFri9DkdxnqCSA/viewform?usp=publish-editor). Slido: #tatryit **PROGRAM:** 18:00 Privítanie 18:10 Salesforce: viac než len CRM 19:00 Q&A a Networking Event budeme [streamovať](https://www.youtube.com/@tatryitcommunity/streams) a môžete si ho pozrieť aj neskôr na YouTube kanáli Tatry IT community (https://youtube.com/live/XrcPOTK6zm0).

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'! Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life. Mission: grow, support, and provide community for atheists in Central Ohio. Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists. All attendees are welcome but should support our vision. Atheists of Columbus (AoC) is part of Omnipresent Atheists (OA).

AoC was founded in 2012 as a networking, social group for Central Ohio area humanists, skeptics, atheists, agnostics, nonbelievers, freethinkers, and the curious. It was a member of Columbus CoR and held weekly meetings, mostly on Fridays, for several years but then operated as an online only group for some time. In November 2018, Omnipresent Atheists (OA), a group that routinely meets on Tuesdays, invited AoC to merge. Omnipresent Atheists is a member of the Columbus Coalition of Reason (ColumbusCoR.org).

Join us as we get together to get together to help those in need at this CMG Gives Back event! We have a great little community of Movie Group friends so rather than see a movie this time, we’ll help “create a better world” by helping serve those in need. Here are complete details and our plan for this event: FAITH MISSION – GRANT KITCHEN: The Faith Mission kitchen and dining room serves residents 3 meals a day, every day of the year. For this event, our group will help prepare food, serve meals, assist residents in the dining room, wash dishes, and clean surfaces. PLAN: We will be preparing / serving / cleaning for BRUNCH from 10:30am to 12:30pm and have space for a total of 7 volunteers. Please arrive at 10:20am and wear closed-toe shoes and long pants. LOCATION: Faith Mission – Grant Kitchen is located at 245 N. Grant Ave. Enter the kitchen at Dock 1 (in the back of the building), indicated in the attached map. On-site parking in the adjacent lot and street parking is available in the surrounding area. Below are some links / attachments with additional info/details: IMPORTANT REMINDER: Our group will be providing all of the volunteers on this day so a firm RSVP count is essential. Please only sign up if you are certain you’ll be able to attend. If something unavoidable comes up, please try to update your RSVP no later than one week prior to the event. With few exceptions, no shows or cancelations within 1 week of the event will not be eligible for future CMG Gives Back events. I appreciate your understanding as we try to ensure the agencies have the volunteers needed to provide the essential services they provide to the vulnerable population they serve. Our Partner Agency for this event is Lutheran Social Services! A huge THANK YOU to all of YOU for volunteering at this (and any of our previous) CMG Gives Back events! Should be a good/fun/meaningful time together, Dan
