OpenTelemetry part 4: Instrumenting Fastly Fiddle

Andrew Betts

We are very excited about OpenTelemetry. We wrote about why, and also about how to emit telemetry from Fastly's VCL services, and our new Compute platform. But OpenTelemetry's value truly shines when you add it to everything in your stack. What does that look like and is it worth it? We instrumented Fastly Fiddle, from top to bottom, to find out.

ESI and the story of libraries built for the edge

Kailan Blanks

Traditionally, content delivery networks have been built upon a proprietary core product which is supported by equally proprietary add-ons such as image optimization and content filtering. Fastly has always done a bit better than this – from the beginning, building our network on the Varnish cache gave our customers the ability to fully program how requests were served at the edge. However, the constraints of VCL, the domain-specific language used to configure Varnish, meant that you were limited to only the features that we chose to offer.
