We’ve all dreamed at one point or another about having safety guards on everything we do — such as keeping erratic drivers away in city traffic, avoiding illnesses, and making sure the food we eat doesn’t make us sick. Now there are real-time guardrails in software development that ensure all code works and doesn’t crash, no matter its state. Durable Execution is a software development framework that makes code fault-tolerant by automatically persisting its state, allowing long-running processes to resume exactly where they left off after crashes, network failures, or restarts.
