Software Architecture

Dear Community, this March we are gathering as part of [Exasol Xperience 26](https://www.exasol.com/events/exasol-xperience/). This is an event worth being part of, Exasol team was so kind to host us for the evening. Please visit the event page and chech the exciting agenda. Distinguished speakers, inspiring topics! If you would like to attend the event free of charge, let us know and we will provide you a ticket. If you prefer to attend our session only, register with your full name below. We also have two awesome speakers that will fill the night with AWS content as usual! 18:30 - Warming up and networking chat 18:45 - Intro by AWS UG Berlin & Exasol 19:00 - 19:40 - **Philipp Hoyer // An AWS Container Journey - The Good, The Bad and The Ugly featuring ECS and EKS** EKS on Fargate promises fully managed Kubernetes without EC2 management, but it comes with more hidden complexity than expected. In this talk, I compare running containers on AWS Fargate with EKS versus ECS based on real project experience. Philipp is Senior AWS DevOps Engineer at Rackspace Technology, where he helps automotive customers design and operate reliable cloud and container platforms on AWS. 19:40 - 20:00 - Network break with snacks & drinks 20:00 - 20:40 - **Piotr Pabis // How we cut ECS Startup by 30% - SOCI Deep Dive** "What are docker images anyway? How are they formed? What is a other container registry? I want to go from first principles - presenting TAR files, composing an image, combining it with a JSON manifest and explaining how SOCI technology improves the speed of lazy loading required files and layers. HTTP range requests, GZIP table of contents, many things. I will try to make it understandable for the casual Docker user as well as nerds who want to know how this works under the hood." Piotr is a Senior Platform Engineer at About You and a well-known Community Builder in AWS. He works mostly improving legacy projects, Terraform and migrating old stuff to ECS. =================================================== **Very Important: There is no "waitlist" for our regular sessions.** However, there are limited seats available.

He's back! The inventor of EventStorming is once again joining the Berlin Collaborative Modeling Meetup for an evening of massive learning, massive laughter, and no doubt a massive number of sticky notes. Here is the agenda: **Collaborative Reverse Roadmapping** We'll put future events on a timeline to build the future we want to happen and make it tactically sound. We'll leverage ideas from * EventStorming (surprise!) * Futurespective * Traditional planning And we'll explore a tool that will enable strategic planning and overcome deadlocks. This is a rare opportunity to spend time with a true thought leader in the DDD community and the person who contributed to the world the whole premise of our meetup. He's full of insights and stories, wit and wisdom, and we are lucky to have him drop by to share them with us. Don't miss this one! **Please do not RSVP if you do not intend to come. For this event only, we have to limit attendance.** As always, everyone is welcome. You don't need to be a software engineer to participate.

Chitta Walks is for people whose days move fast, while the mind never fully lands. Thoughts keep looping even when nothing is urgent. The body moves, but attention is elsewhere. Over time, this disconnect drains clarity and ease. This walk is a simple reset. We meet in Berlin’s Tiergarten and walk at a gentle pace. Parts of the walk are in silence, with light guidance and a few short prompts. The walk itself is the practice, bringing body and mind back into the same moment. No apps. No performance. Just a clear space to slow down and notice what is happening. If you want to slow down without withdrawing from life, join a Chitta Walk. ✨ **What to expect (approx. 90 minutes):** * A short arrival and orientation * A guided silent walk (phones off, no conversation) * One concise science-based impulse on attention or stress * Optional reflection in pairs or small groups * A simple takeaway or experiment for daily life 🚶**Who this is for:** * Professionals, creatives, and people in transition. * People who feel mentally busy and want more clarity and balance. * Those curious about mindfulness, but grounded and practical. * Anyone comfortable with silence and gentle self observation. 🔔 **Practical notes:** * Duration: 60-90 minutes * Wear comfortable shoes and weather-appropriate clothing * No prior experience needed * Group size is limited to keep the space quiet and focused 🧭 **Facilitator:** My name is Partha Sarathi, you can call me PS. I have lived in Berlin for over 12 years. With a background in physics and materials science, my interest in mindfulness grew through personal experience with stress and health challenges. I facilitate the space and structure of the walk, inviting shared exploration rather than instruction. 🤔 **Why Chitta Walks?** Chitta is a Sanskrit word referring to the mind or field of awareness, used here in a practical, non-religious sense. Chitta Walks is about noticing how the mind works by slowing down and walking together. Mindful walking makes thought patterns visible in real time, while moving and sensing in the world. The name points to a simple capacity: noticing what is happening in the mind without immediately trying to fix, judge, or optimize it. 🌿 **Possible effects:** A calmer nervous system. Clearer attention. A felt sense of being more present in your body. Subtle insights into how your mind reacts under everyday conditions. A quieter, more grounded way of moving through the city. **Come as you are. Walk. Notice. Leave with a little more space inside.**
