DevOps at Scale: Achieving a Zero-Downtime Migration for 80 Million Daily Requests
How do you pull off a seamless data platform migration in a mission-critical environment—without taking your systems offline? In this talk, we’ll delve into how our team leveraged DevOps and agile principles to execute a zero-downtime migration from AWS OpenSearch to Elastic.co’s Elasticsearch, handling over 80 million daily requests.
Attendees will learn how we used parallel ingestion pipelines, weighted routing for gradual traffic cutovers, and massive data synchronization to ensure a smooth transition. We’ll highlight the observability and feedback loops that guided our decision-making, along with the iterative practices that allowed us to pivot quickly and maintain confidence throughout the migration. You’ll walk away with practical insights on designing resilient architectures, mitigating risk, and applying DevOps best practices to tackle large-scale migrations—without leaving your users in the dark.
The Road to Mordor: An Engineer's Guide to Simplifying Complex Features
We’ve all been there—your company has a groundbreaking new idea, and your team gets the exciting task of bringing it to life. It can be both exciting and nerve-wracking. Your challenge lies in navigating through a sea of unknowns to transform this vision into a tangible, production-ready solution. It can feel like embarking on an epic journey, full of obstacles and uncertainty.
In this session, we’ll explore practical strategies for turning what seems like an impossible task into a successful project. We’ll walk through techniques to break down complex features into manageable parts, convert unknowns into knowns, and deliver functional products. Whether you’re solving technical challenges or steering the project forward, this talk will help you navigate the road ahead, ensuring your project reaches its final destination—without falling into the fires of Mount Doom.
Leveraging LLMs with Spring AI
In 2025, it’s hard to find an application that isn’t enhanced with some form of AI capabilities. If you’re curious about the AI buzz but unsure how to integrate it seamlessly with your existing Spring applications, this session is for you. We’ll explore essential AI terminology and create a Spring-based application that easily integrates with various Large Language Models, such as OpenAI’s GPT-4o. Time permitting, we’ll demonstrate creating effective prompts, utilizing OpenAI’s function calling, and implementing Retrieval Augmented Generation (RAG).
Lightning-Fast Lambdas: Modern Java’s Comeback on AWS
You’ve heard the rumors—Java is “too slow” or “too heavy” for serverless. But what if we told you that modern Java frameworks can deliver near-instant cold starts and rival typical Lambda languages on AWS? In this session, we’ll dispel outdated myths by building a small Quarkus-based Lambda for a real-world scenario, showing how you can keep startup times low and memory costs minimal. We’ll compare performance metrics, walk through native image builds with GraalVM, and show how Java’s new breed of frameworks is turning skeptics into believers. Join us to see how you can harness the power of Quarkus, reduce those dreaded cold starts, and prove that Java is more than ready for the serverless era.
