The author speaks in a sober tone that reflects his long periods of experience and insight. Patterns and techniques such as sidecar, adapter, ambassador, sharding, replication, leader election are explained alongside sample code implementations. Since he is associated with Kubernetes, it is a prominent presence in all examples, which skews the narrative towards container orchestration, making one wonder if the choice is always worth the complexity. The discussion is neither too deep (the gold standard remains Designing Data Intensive Applications by Kleppmann) nor too shallow (as happens in scores of "system design interview" books and blogs). At only around 200 pages, it is a swift read with good takeaways for beginners to scalable and fault tolerant architecture design.
