Introducing Tripod: Flickr’s Backend, Refactored Peter Welch (Senior Principal Engineer, Flickr)
Peter recently led the re-architecture of Flickr’s back-end services to create a new platform called Tripod, which is used at large scale for Yahoo Mail and other consumer services. This talk will cover building Tripod APIs in Yahoo's global context required a deep focus on eventual consistency challenges, sparse APIs and content deduplication. The team also had to figure out how to build an active/active system to ensure high availability.

Searching for the Best Learning Content Karen Sun (Engineering Manager, Quizlet)
Quizlet is the most popular online learning service in the US and has amassed over 5 billion user generated flashcards in dozens of languages across all areas of study— medicine, math, foreign language study, standardized tests, and more! Quizlet leverages this enormous bank of knowledge to connect users with highly corroborated and customized learning material for any concept they need to master. We will discuss the strategies we've employed to tackle both global subject-level document search and aggregation based concept-level search on top of Elasticsearch. We'll cover lessons learned related to optimal document structure, pre-processing strategies, sharding configurations, and cluster stability.
Karen Sun leads the Backend/API and Data Science teams at Quizlet, focusing on building their data platform to support studying, teaching, and the cognitive science research that powers all the app experiences.
Tenements in the Troposphere Scott Maher (Sr. Tech Lead, Twilio)
Distributed systems built on top of the cloud need to consider the material of their foundations; ever changing and susceptible to chaotic environmental effects. This talk is about building microservices for reliability when downstream components will be flaky or unpredictable. We will discuss managing fairness and reliability with techniques like quotas and bulkheading in multitenant async IO heavy services and how we build them with Akka Actors, Akka Streams, and Scala.
Scott Maher is a senior tech lead at Twilio. He previously led development for their SMS and MMS platforms, and is now connecting Twilio with dozens of OTT messaging and IoT networks like Facebook Messenger and Amazon Alexa.
