Talk : Lambda Architectures: a Snapshot, a Stream, & a Bunch of Deltas

Track : Architectures You've Always Wondered About
Location : Fleming, 3rd flr.
Day of week : Tuesday
Duration : 1:40pm - 2:30pm
We all got so excited about breaking apart our monoliths and liberating our microservices. At HBC Tech, our work on luxury e-commerce experiences across gilt.com, saks.com, lordandtaylor.com, thebay.com and saksoff5th.com shows us that unconstrained, organic growth of microservice architectures can lead to a system with high numbers of inter-service dependencies (some of them hidden!), and deep call stacks. We asked ourselves the question: “how can we architect, build and run our services resiliently and at scale so that they can respond to requests without any immediate downstream dependencies?” Our approach is to leverage event-sourced architectures that allow core services to reliably share their information with other services asynchronously. At the heart of each solution is the snapshot, the stream, and a bunch of deltas. 
In this talk I’ll give examples of these architectures in practice in our product, pricing, inventory and search services, the technology choices that have stuck: AWS Kinesis, AWS S3, AWS Lambda, Elasticache, and  Calatrava. I’ll discuss how we’re making our way towards adopting Kafka as our backbone streaming implementation. And, I’ll show how we’ve begun to apply the techniques not just internally but also with external third-party vendors to keep our runtime dependencies low.
