Episode notes
HTTP/2 Brought Load-Balancing Pain
- TrueLayer found HTTP/2 tricky in production due to load-balancer behaviour and implemented client-side load balancing for gRPC.
- They published a Rust library to address HTTP/2 client-side load balancing challenges.
The Real Challenge Is Ecosystem Choice
- The hardest part of using Rust in backend is choosing and constraining the ecosystem tools to create a maintainable platform.
- Providing clear internal guidance prevents each engineer from reinventing tracing, auth, and testing patterns.
Prefer Evolving Libraries Over Rigid Generators
- Use generators for boilerplate but avoid treating them as long-term architecture migration tools.
- Prefer libraries that evolve with you for day-two maintenance over rigid templates.
