Abstract
This talk explores Corrosion, an open-source solution built on SQLite that delivers fast, eventually consistent replication across distributed nodes. Initially developed at Fly to replace Consul for service discovery, Corrosion has evolved to power the platform, enabling the rapid dissemination of machine and service data across numerous nodes with a p99 latency of one second. Leveraging technologies such as Conflict-free Replicated Data Types (CRDTs) for conflict resolution, the SWIM gossip protocol for membership management, and the QUIC transport protocol, Corrosion is implemented in Rust and is open-source. In this talk, we will explore these technologies, dive into architectural and design decisions, and discuss how Corrosion is used in production at Fly. Whether you're familiar with these concepts or they're new to you, join us for an in-depth look at Corrosion.
QCon London 2025 is a three day conference for senior software engineers, architects and team leads. An international program committee of working engineers selects every session. Patterns and practices, not products and pitches.

10:35 Fleming (3rd Fl.) Session architecture Architecture in the Lead: Scaling Today, Shaping Tomorrow Matthew Clark, Ian Arundale The BBC’s websites and apps handled well over 100 million visitors in 2024, with 40 million people arriving on UK Election night alone. That’s a lot of scale for an architecture to handle, but it’s just the beginning. 11:45 Whittle (3rd Fl.) Session augmented reality Developing Meta's Orion AR Glasses Jinsong Yu Software Engineer @Meta, Led the Development of Orion AR Glasses Software Stack, Previously @Google and @Microsoft Meta announced the Orion AR Glasses in September 2024. It is a time machine to demonstrate that it's possible to build an immersive augmented reality experience in a glasses form-factor. There were numerous technical challenges to make this a reality. 13:35 Rutherford (4th Fl.) Event Connecting the Dots: Architectures (Limited Space - Registration Required) 14:45 Churchill (Ground Fl.) Session AWS serverless Kraken's Serverless Architecture for Keeping the Grid Green Kevin Bowman Platform Engineering @KrakenTech (Octopus Energy), Previously @SkyBet and Others, Passionate About Removing Friction From Getting Stuff Successfully Into Production The green energy transition is real, and happening, but it needs technology to make it successful. Everything from renewable energy generation onto the grid, to how consumers use energy, needs technology to be effective and keep up with today's demands. 15:55 Whittle (3rd Fl.) Session Fast Eventual Consistency: Inside Corrosion, the Distributed System Powering Fly.io Somtochi Onyekwere Software Engineer @fly.io, Previously Developer Experience Engineer @Weaveworks This talk explores Corrosion, an open-source solution built on SQLite that delivers fast, eventually consistent replication across distributed nodes. 17:05 Fleming (3rd Fl.) Session AI/ML Lessons Learned From Building LinkedIn’s First Agent: Hiring Assistant Karthik Ramgopal, Daniel Hewlett In October 2024, we announced LinkedIn’s first agent, Hiring Assistant to a select group of LinkedIn customers.
