When We Took Critical Paths Off Lambda-and Why It Had to Happen
Article summary
When We Took Critical Paths Off Lambda-and Why It Had to Happen We didn’t move away from Lambda because it failed. We moved away because it worked exactly as designed-just not in the ways our systems actually needed to behave under pressure. The problem started with a checkout delay. One customer timed out. Then five. Then a hundred. Our dashboards were green. Error rates were low. But something felt off. The trace confirmed it: multiple Lambdas invoked asynchronously across four flows-each retried, some throttled, all opaque under load. We had optimized for scale. What we lacked was control. Where Serverless Began to Show Its Edges Failures didn’t look like failures. Lambdas retried quietly, masking downstream slowness. By the time retries stopped, the user had long since given up. Timing became guesswork.
