BAC-L3-OPS-112
Public RPC infrastructure
Serving developers without exposing your validators: load balancing, caching, rate limiting and strict isolation.
- Level
- L3 — Infrastructure engineer
- Duration
- 4 h
- Maintainer
- DevOps / Blockchain Infrastructure Engineer
Learning objectives
- 01Expose a load-balanced, cached RPC service
- 02Rate-limit per caller without penalising legitimate use
- 03Fully isolate consensus nodes from the public service
Guided lab
Deploy a public RPC service with caching and rate limiting, then measure how it holds under load.
Independent lab
Size and cost BAC's public testnet RPC service.
Security angle
Filter the methods exposed: some queries alone are enough to freeze a node.
Assessment
Service under load, with a performance record and filtered methods.
