Building resilient systems with Sam Newman

Newman says AI labs face a $2.6T revenue gap by 2030, so engineers should hedge with multi-vendor, modular, deterministic-leaning architectures.

  • Microservices as last resort: Sam Newman, co-author of the original microservices concept with James Lewis, says the architecture should only be used when organizational autonomy is the explicit goal, not a default choice.
  • Three rules of distributed systems: Newman's new book 'Building Resilient Distributed Systems' distills failures to three causes: network latency isn't zero, remote components sometimes aren't reachable, and resource pools are finite (the cause of most outages).
