You are effectively scaling your software teams to their maximum efficiency. When is the right time to automate specific features to accommodate your growing team? This week we’re joined by Matt Ranney, Principal Engineer at DoorDash who emphasizes the importance of finding productivity angels in smaller teams with more automation, and how understanding that unit testing isn't the only valuable metric can lead to building more efficient infrastructure systems.Matt also discusses the pros and cons of Kubernetes and microsystems, and provides call-to-actions when Doordash experiences failures or downtimes on microservices. He stresses the importance of acknowledging that partial failure is still complete failure, and how taking steps to prevent and mitigate these failures can greatly improve overall system reliability.Join as we discuss:Finding productivity angels: Discover the importance of finding productivity angels in smaller teams with more automation.Valuable metrics beyond unit testing: Unit testing is important but don’t let it get in the way.Get tips on how to prevent downtime and mitigate failures on microservicesThe importance and power of Change Data Capture

Building Reliable Systems with DoorDash's Matt Ranney

“If you can make a system that can survive this random failure testing, then you will more or likely survive whatever other chaotic conditions exist.” Uber is a transportation and logistics company that manages many aspects of its ride-sharing services through mobile apps and distributed technology. Uber faces unique challenges in rapidly scaling its services internationally, and at one point increased its developer headcount from 200 to over 1000 in less than a year. Matt Ranney is the Chief Systems Architect at Uber and was previously a founder and CTO of Voxer. At QCon San Francisco, he gave a talk called Scaling Uber. Questions  How did technical debt accumulate at Uber in the first five years? Why do microservices offer a strategy to help alleviate technical debt? Could you discuss immutable infrastructure? What is Ringpop, and how does it help maintain state? What are the service discovery problems you’ve had while scaling? How have you “embraced the chaos” recently?
