Problems 🪨🪐🌌 Distributed systems introduce significant nondeterminism to our programs. Sources of non-determinism include unsynchronized parallelism, unreliable components, and networks with unpredictable delays. As a result, a distributed program can exhibit a large space of possible behaviors on a given input. — Hellerstein & Alvaro, Keeping CALM: When Distributed Consistency is Easy

Problems 🪨🪐🌌 And Yet…
Problems 🪨🪐🌌 And Yet… These metastable failures have caused widespread outages at large internet companies, lasting from minutes to hours. Paradoxically, the root cause of these failures is often features that improve the efficiency or reliability of the system. – Bronson et al, Metastable Failures in Distributed Systems
