Alternative Energy

***[IMPORTANT NOTICE registration is HERE](https://luma.com/j8czeuvr)*** Join **Aerospike, Start.io, and Contentsquare** for an evening of deep technical talks and peer-level discussion on the real trade-offs behind operating modern real-time systems in production - where tail latency, throughput predictability, scalability, and cost efficiency are constantly in tension. This event will move past theory and into hard-earned production lessons: scaling beyond RAM constraints, migrating high-throughput workloads from Redis to Aerospike, designing architectures driven by real cloud cost models, and uncovering the non-obvious pitfalls of migrating real-time systems from AWS to GCP. Topics range from VPC architecture and traffic steering differences to NVMe and local SSD behavior, and why familiar operational playbooks often fail across clouds. This event is designed for engineers and architects already running latency-sensitive, high-scale systems - where milliseconds matter, growth is relentless, and infrastructure decisions directly impact performance, reliability, and cost. ​ **Agenda** **​17:30 – 18:00 - Welcome drinks & networking** ​**18:00 – 18:10 - Opening Remarks – Speed vs Capacity: Designing Data Systems for Real-Time Scale** *Oshrat Ben-Avi Zabludovitz, Israel Country Manager, Aerospike ​* **18:10 – 18:30 - Scaling Past RAM: Architecture Lessons from Our Redis-to-Aerospike Migration** *Ilan Huchansky, Data Platform Team Leader, Start. io* ​As Start.io scaled, our legacy Redis-based architecture for the user-profiles database reached significant operational limits, particularly during high-traffic periods, node failures, and scaling events. To maintain our strict performance SLAs while reducing operational overhead, we embarked on a search for a more robust, cost-effective NoSQL solution. In this session, we will share the architectural lessons learned while evaluating the database landscape - including our comparisons with alternatives - and our ultimate migration to Aerospike’s Hybrid Memory Architecture. We’ll discuss how we moved past RAM constraints to achieve sub-millisecond performance at massive scale without compromising on availability or data consistency. ​ **18:30 – 18:50 - Boosting Cost Efficiency with Cost-Aware Architecture** *Doron Hoffman, Chief Architect, Contentsquare* ​ In this session, we explore the critical role of cost-aware architecture in achieving optimal cost efficiency for modern software systems. As organizations increasingly rely on cloud services, microservices, and distributed computing, understanding and managing costs becomes paramount. ​We’ll discuss the shift from traditional architecture to cost-aware design and examine how architectural decisions directly impact operational expenses. Through a real-world example, we’ll share lessons learned from evaluating multiple cloud providers and their services using cost models and how rearchitecting with cost as a first-class concern made a measurable difference. ​Attendees will gain practical insights into designing cost-efficient systems that balance performance, scalability, and financial constraints, enabling more sustainable growth. ​ **18:50 – 19:10 - The Latency Leap: Hard Lessons in Migrating Real-Time Systems from AWS to GCP** *David Gerchikov, Senior Software Engineer, Aerospike* ​ Moving a stable web application between clouds is challenging; migrating a high-throughput, real-time system is far more delicate. When heartbeats are measured in milliseconds, the “invisible” differences between AWS and GCP—from VPC architecture to NVMe and local SSD behavior—can determine whether a migration succeeds or fails. ​This session goes beyond basic service mapping to explore the real friction points of moving a real-time engine from AWS’s regional model to Google Cloud’s global fabric. We’ll cover networking and traffic-steering gotchas, why AWS operational playbooks often don’t translate, and how storage lifecycle constraints in GCP Local SSDs force changes in node management to preserve predictable performance and reliability. ​ **19:10 – 20:30 - Networking and fun** ***[IMPORTANT NOTICE registration is HERE](https://luma.com/j8czeuvr)***

How Claude-powered systems actually get hacked. We'll go straight into the attacks people are running right now: prompt injection, jailbreaks, agent and tool exploits, and what red-teaming the Claude ecosystem really looks like. 🍕 **18:00 – 18:30** · **Gathering, Pizza & Drinks** 📣 **18:30 – 18:45** · **Welcome + Latest Claude Updates** · Organizers 💻 **18:45 – 19:15** · **JavaScript Is All You Need: Exploiting Agentic Workflows for API Key Theft** · Eden Katz, GenAI Security Tech Lead @ Alice. Building with AI APIs? This one matters. Alice's research shows that API key creation on platforms like Anthropic relies on cookie-based auth alone — so a malicious browser extension or a compromised agent skill can silently mint a new key and ship it elsewhere. No MFA, no warning, no expiration. As agents get trusted with autonomous code execution and client-side access, the line between safe tool use and serious vulnerability collapses. JavaScript really is all you need. 👾 **19:15 – 19:45** · **Securing coding agents: Unpacking Threats and Defences** · Bar Kaduri, Principal researcher @ Capsule Security *AI coding agents like Claude Code, Copilot, and Cursor now write, execute, and ship code with unprecedented autonomy, often straight to production. But this privileged access opens a unique attack surface, as recent incidents like prompt poisoning and deleted databases reveal. This session breaks down the real-world threats facing coding agents and delivers practical, actionable defences for securing your AI-assisted development pipeline.* 🍻 **19:45 – 20:00** · Drinks & Geek Out

Join us at Unity of Columbus for our Weekly Reiki Share, a peaceful and uplifting gathering for connection, healing, and growth. A Reiki Share is a time where Reiki practitioners and students come together to give and receive healing energy in a supportive and welcoming environment. These sessions will be moderated by Columbus Unity Reiki. Reiki is a hands-on energy healing method from Japan that first came to the United States in 1938. Since then, it has grown in popularity and is now widely practiced throughout the West. All levels are welcome, and you do not need to be a practitioner at Unity of Columbus to attend. If you are a Reiki practitioner, a Reiki student, or simply interested in becoming a Reiki student, we warmly invite you to join us. Come practice your healing techniques, learn new approaches, receive healing energy, and connect with a like-minded community in a space of relaxation, renewal, and positive energy.
