Debate: Did my AI training pipeline crash because I went with cloud GPUs over local rigs?

I was in my basement workshop last Thursday, running a batch of 5000 synthetic training images through a custom pipeline I built for medical scan analysis. Halfway into epoch 3, the whole thing froze. I SSH'd in and saw the cloud instance had dumped my session due to a memory allocation error, costing me 12 hours of progress and $40 in compute credits. I spent the next 2 hours debugging and realized my data loading script had a memory leak I never caught because I was too lazy to stress test it locally first. I'm arguing that cloud setups are great for scaling but a local rig would have forced me to catch that bug early since I'd hit RAM limits faster. But my buddy says the cloud flexibility is worth the occasional crash. What's your take, should I build a dedicated local PC for prototyping or stick with cloud and just write better code?

Wait, are you sure the cloud instance is what caused the crash? It sounds like your data loading script had a memory leak, which is a coding bug, not a cloud vs local problem. Honestly, a local rig would've hit that same memory leak eventually too, just maybe faster because you'd have less RAM. Tbh, the cloud setup didn't cause the leak, it just exposed it when you tried to scale up. Ngl, blaming the cloud for a bug in your own code feels like a cheap way to avoid owning the mistake. You'd still have to fix that leak whether you're on cloud or local, so the real fix is just testing your pipeline with smaller batches first.

@barbara_sanchez88 makes a good point. I read cloud devs screw up leak testing all the time.
