The most popular book matching your request is actually written by (often misremembered as Alex Wu), titled " System Design Interview – An Insider’s Guide.
Wu distinguishes between Layer 4 (transport) and Layer 7 (application) LBs. He explains common algorithms: round-robin (stateless, simple), least connections (for long-lived sessions), and consistent hashing (for caching). The key trade-off: LBs introduce a small latency hop but eliminate single-server failure as a system-wide bottleneck. He also warns against LBs becoming a single point of failure themselves, hence active-passive or active-active LB clusters. alex wu book on system design
