Sessions Montréal 2026
Accelerate Docker Image delivery with Varnish caching
Session en Anglais - Débutant
Organizations relying on Docker need fast registries, but at scale image pulls slow down, raise costs & create bottlenecks.
This talk shows how Varnish is optimized to cache Docker image manifests & image layers to dramatically boost performance & developer efficiency. We’ll examine the HTTP requests behind the "docker pull" command & cover caching strategies for public and private repos while preserving authentication and access controls.
Leveraging the edge for observability
Session en Anglais - Intermédiaire
Many teams use CDNs or caching proxies for speed and scale, but often overlook their value for observability.
In this talk, Thijs shows how to turn Varnish into a rich observability layer—unlocking metrics and logs already flowing through the proxy, integrating with Prometheus, Loki, and Grafana, and standardizing data with OpenTelemetry—making your proxy not only a performance booster, but also a key source of insights.
