Who is this presentation for?

  • Big data engineers, senior analytics engineers, and senior software engineers

Prerequisite knowledge

  • Familiarity building any data ingest pipeline
  • Basic knowledge of Kafka and the stream processing domain (useful but not required)

What you'll learn

  • Explore how Netflix is building a scalable, self-service, fault-tolerant multitenant stream processing service in the cloud by leveraging Kafka, Samza, Flink, Mesos, and Docker and how it is evolving the service in flight without downtime


The need for gleaning answers from data in real time from unbounded data streams is moving from nicety to a necessity. Netflix is a data-driven company, and Netflix Keystone SPaaS processes over a trillion messages a day with at-least-once processing semantics in the cloud to derive insights. To ease extracting intelligence from this unbounded stream easily, Netflix is building stream-processing-as-a-service (SPaaS) infrastructure so that the user can focus on extracting value and not have to worry about building a scalable, fault-tolerant infrastructure.

Monal Daxini explores how Netflix is building a scalable, self-serve, fault-tolerant, multitenant stream processing service by leveraging open source software like Kafka, Samza, Flink, Mesos, and Docker, how it is evolving the service in flight without downtime, and lessons learned along the way.
