Amazon FSx for Lustre
- davidmr 8y agoThis was inevitable, and I’m sure the engineering from Amazon’s side is impressive because Lustre is an absolute beast to run well at scale, but I’m not sure how great an idea it is for most people. Coming from an academia HPC background and then moving into the private sector, I’ve mostly come to believe that parallel filesystems (especially POSIX-compliant ones) are rarely the right solution outside of MPI simulations. Like NFS, it makes it extremely easy and attractive to implement anti-patterns like using the filesystem for IPC or generating a bazillion files and then needing to reduce them to move to the next stage of the pipeline. In my experience, it’s rare that people don’t regret doing that sort of stuff in the long run. That said, I’m sure the AWS team knows their customers and what they’re doing better than I do!

- SSilver2k2 8y agoThis week is the AWS re:Invent conference, so every day new services are being introduced.
- damnhungry 8y agookay, my apologies :)
- SSilver2k2 8y agoit's all good :)
- colmmacc 8y agoAWS re:Invent, AWS's annual conference, is currently happening in Las Vegas. There are quite a number of headline announcements each day to go along with each keynote (there are 4 total).
- fold_left 8y agofinally, something that can handle node_modules! :)
- tardismechanic 8y agoAyyy!
- pinewurst 8y agoThat would have to be the worst job in the world - keeping Lustre going as an Amazon service, with management that utterly lacks understanding and sympathy.
- davidmr 8y agoThey’d have to pay me a lot of money to do it, that’s for sure. I’d love to see the disaster recovery plans. Every major Lustre site I’m aware of has had a data loss “incident” at some point in their history. It’s possible AWS has it all figured out with background backups and block device replication and whatnot, but I’m skeptical.
- mbreese 8y agoGiven that they call the non-S3 linked version 'ephemeral', I'm not sure there is a plan. I think S3 is the plan.
- pinewurst 8y ago'Ephemeral' was/is the original Lustre design model. It was intended for high performance swap/scratch at Livermore with a short data lifespan - your higher priority bomb sim forces mine to roll out to disk and back in later, and that's it. Lustre, even today, isn't long term stable. The longer you leave data on it, the greater the probability of corruption - even silently.
