We all know DevRel (Developer Relations): our company brings a novel approach to the industry, a new and better way of doing things, and we need someone to evangelize this concept, this approach, and then our product. But what if your company has an open source play? Clearly DevRel has a major stake in that, but how exactly does it work? In this talk, Horovits will share his DevRel experience around OpenTelemetry, Jaeger, OpenSearch and other prominent projects, and will offer some best practices and guidelines running an effective DevRel program for open source. Whether you found your own open source project, or whether there’s an established OSS project your company wishes to get involved in, this talk will give you fruit for thought.
