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.

Recently, I was working with a client who was leveraging Burstable T2 EC2 instances for their web infrastructure - something which I regularly recommend to my clients. In this situation though we were receiving reports from the application team about odd behaviour. On what seemed like a random schedule the websites would stop responding to requests entirely or complete the requests at a reduced rate.
We immediately started to comb through our logs in an attempt to determine the cause and implement a fix. Based on CloudWatch metrics which we were already capturing it appeared as though we had a memory leak in one of the applications running on the Apache Server.

What a week. I’ve been hearing from all sorts of people (customers, students, co-workers) about the S3 outage - some even referred to it as the #S3apocalypse.
I’ll let you all in on something. It’s all FUD (Fear, Uncertainty, and Doubt). Every single person who is writing articles, or tweeting about the effects of the outage is using the S3 outage to try and sell you something - myself included. They are telling you that you need multi-cloud, that you need to go back on-premise (because we all know this would have never happened on premise right?) or maybe even switch cloud providers.
