Who is this presentation for?

  • Developers, infrastructure engineers, and architects



Prerequisite knowledge

  • Familiarity with microservices, containers, Docker, and application architecture

What you'll learn

  • Learn what to consider when adopting a microservices architecture along with strategies for doing service discovery, routing, running a service mesh like Istio or Linkerd, and evaluating orchestration solutions like Kubernetes and Swarm
  • Discover how to think about observability, monitoring, and distributed tracing to understand what's going on in a microservices system; the impact on developers when dealing with coding, testing, and deploying microservices
  • Explore the cultural impact of adopting microservices on teams


Over the past two years, Credit Karma has gone from zero to nearly 100 microservices, supporting over 300 engineers while serving our more than 80 million members. Drawing on his experience at Credit Karma, Mason Jones shares approaches based on his real-world experiences making the shift to microservices, covering routing (How does service A find and call service B?), management (How do you handle hundreds of containers?), observability (How do you know what’s going on out there?), and experience (How do your developers deal with these services?), as well as the cultural and organizational impact that you can’t avoid. Join in to explore solutions, pitfalls, and practical examples that have worked in the real world at scale.
