Airbnb’s Great Migration: Building Services at Scale

So you’ve decided to migrate from monolith to microservices, what next? Such a redesign to service-oriented architecture (SOA) is a long, arduous journey that benefits from an incremental, iterative approach. Yet, such a migration often must be done while still shipping new features, accelerating developer velocity, and growing the team in addition to ensuring there are no performance regressions.

This talk recaps my QCon SF 2018 “Great Migration” presentation then continues the story with a focus on how Airbnb is building, operating, and scaling its expanding network of services. Though our re-architecture to SOA is still ongoing, we are already seeing various benefits including improved performance, developer productivity, build and deploy times, and site reliability.

Key takeaways: 

• Understand design principles for building scalable, performant services
• Plan for dependencies: how to sequence decomposition into services and an API gateway
• Learn best practices for standardization, reliability, and performance when migrating architecture
• Identify ways to shift product culture to empower migration work
• Recognize tradeoffs with operating microservices

Real World Examples of FaaS

Cloudflare launched Cloudflare Workers over a year ago bringing the ability to run JavaScript and then any WASM-targetting language on our 165+ locations around the world. Since then many companies have built functions and applications using Cloudflare Workers. This talk will look at real world examples, not proofs-of-concept or textbook ideas, of what's being built using this new architecture.

BBC iPlayer: Architecting for TV

TV apps have seen an explosion in usage over the last few years as audiences start the slow migration away from traditional broadcast viewing. For iPlayer, TV has become the dominant platform, with over half of iPlayer consumption coming from the biggest screen in the house via thousands of models of smart TVs, streaming sticks, games consoles and set top boxes. Achieving universal reach — whilst also pushing the boundaries of experience — comes at a price however. In this talk we explore the challenges of TV application development; from our early days chasing new native experiences, to the development of our open source libraries and standards-based certification. We’ll also touch on the next steps for iPlayer as we blur the lines between broadcast and IP television.

What We Got Wrong: Lessons from the Birth of Microservices

Google deserves a lot of credit for imagining (and popularizing) what we now call "microservice architectures." That said, hindsight is 20/20, and many of the mistakes we made at Google are being recreated by the rest of the industry today. What did we get wrong about microservices at Google, and how can we apply those lessons today?

Life of a Packet Through Istio

Istio is a service mesh for Kubernetes that offers advanced networking features. It provides intelligent routing, resiliency, and security features, so that service authors don’t have to keep re-implementing them. Istio is rapidly taking off and there are great introductory talks everywhere. However, in this session, we will dive deep to explore precisely how it does what it does, following one brave little packet in from the internet and back out again. At each point, we’ll see how to configure the features of that component to exploit istio’s full potential. This will give a great insight into Istio’s full power, and its fascinating architecture.
