15. © 2016 Mesosphere, Inc. All Rights Reserved. LESSONS LEARNED 15 microservices are distributed systems* 1. The network is reliable. 2. Latency is zero. 3. Bandwidth is infinite. 4. The network is secure. 5. Topology doesn't change. 6. There is one administrator. 7. Transport cost is zero. 8. The network is homogeneous. *) https://en.wikipedia.org/wiki/Fallacies_of_distributed_computing
16. © 2016 Mesosphere, Inc. All Rights Reserved. LESSONS LEARNED 16 • design team-first • polyglot is good, but: hiring • debugging/tracing (remember? µS are distributed systems) • logging (shipping, retention, auditing) • monitoring—instrumentation is a must! • resilience testing (chaos monkey et al)
