Episode notes
Use File Cache For Large Files
- Move large objects to a file cache on disk and tune thread pools and workspace sizes in Varnish.
- Add tests and split VCL logic to make cache behavior predictable and maintainable.
Cache As A Front-Desk Shield
- A single Varnish instance can shield backends massively, serving terabytes while keeping backend hit rates high.
- Observability reveals which regions are "hot" so you can right-size capacity regionally.
Communicate For Your Audience
