Dependencies, distributed code and engineering velocity

About this Presentation

Most software engineers loathe and fear debugging dependency update issues. They are common challenges in the modern enterprise environment. The proliferation of git repositories, the sharing of reusable code and rise of the microservice all conspire to make organization-wide binary integration a nightmare.

At Netflix, engineers are not immune to the cost of dependency updates. Library owners publish new versions of their code without a comprehensive understanding of the organizational impact. Application owners ingest new library versions that can fail in obvious or subtle ways, leading to decreased confidence and slower organizational velocity. But these are problems we understand, and tooling can help.

In this talk, Mike McGarr (Manager, Netflix Developer Productivity) will talk about the challenges of shared code, dependency management, and some existing solutions. He will then share the approach that Netflix is moving towards to decrease the cost of managing application dependencies at scale.
