Amazon Elastic File System (EFS)
Recently, I was working with a customer who - let’s just say wasn’t having a great experience with [Elastic File System EFS] (https://aws.amazon.com/efs/details/). If you’re not familiar with EFS, just think of it as managed NFS. EFS allows you to share a file system between EC2 instances - potentially thousands of them.
In this particular case, the customer was using EFS to share data between multiple web servers. The problem was (what at first seemed to be random intervals) the website would come to a grinding halt. Throwing 502 Bad Gateway errors in the middle of the day is not something you want to have happen.
