In this talk we will present some highlights from recent research results on how the sizing of router buffers affects Netflix video traffic. Our results were publi …

As applications have increased in complexity, so have the queries needed to understand the state and performance of those systems, leading to an explosion in the volume and dimensionality of metrics. Joel Barciauskas outlines how Datadog architected its pipelines, data structures, and storage engines to answer these complex questions, all while scaling to ingest trillions of points per day.

Blockchain and DLT adoption is rapidly growing with over 80% of Fortune 500 companies already actively exploring and evaluating use-cases. This technology, although offering users enormous transparenc …

Software metrics can be used effectively to judge the maintainability and architectural quality of a code base. Even more importantly, they can be used as canaries in a coal mine to warn early about dangerous accumulations of architectural and technical debt.

The benefits of blockchain across multiple use cases and industries are becoming evident as more pilots and proofs of concept are implemented, including lower costs and increased efficiencies. But mak …

Upfront architecture is essential to ensure reliability. Ideally, the system design starts with defining clear service-level objectives (SLOs) that translate into the right architecture to avoid gold-plating or costly redesigns after the system is live. Marco van der Linden and Tom Hofte explain how to define clear SLOs and apply architectural patterns to design a system that works as promised.
