I went through AWS’ example workloads e.g. analytics, CMS, web serving. Those all seem to be better / more commonly served using other storage (EBS, RDBMS, S3).

Can someone share how high-throughput EFS has been helpful ?

I’ve never had much luck with NFS in the past besides shared home directories. Anything concurrent always seemed to have consistency issues.

We looked at EFS to pair with fargate to run a small server.. we only needed a tiny bit of persistent shared storage (which served pages and config to connect to the DB)... But EFS was atrociously slow for large numbers of small files. I anticipate high throughout would help for applications that want to read/write) lots of small files serially like websites built on frameworks that have thousands of files to read to start or to render a page.

NFSv4 is designed to alleviate the consistency shortcomings of NFSv3, but unfortunately I'm not aware of any client implementations that leverage the full spec as intended. The linux implementations are improving frequently.
