Worse still, we spent weeks on the phone with AWS insisting there was no throttling - just to find out there was throttling. And that would have been discoverable if a single engineer had looked at CloudWatch.
Do you have Enterprise Support? If so, this is a very surprising result.

> They also have hidden limits on the number of incoming tcp connections you can have. Do you have proof of this?
No, I had an experiment I was tried to run on EC2 in 2013, and ran into this. It was very clear though. Established connections would plateau, and then no more tcp syns would arrive to the ec2 host, unless a connection was closed. At the time the limit was 5000 connections on the micro instance -- from my notes, we got an allocation for hi1.4xlarge and I know we hit the limit there too, but I don't recall what the li…

The "Connection Tracking" portion of http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-net... provides some insight here and describes a method to avoid connection tracking in EC2's firewall.

That is basically what a Project Manager does, and from my perspective it is a lot more valuable then what can been seen form both inside and outside.
Fair enough. Maybe I should say that I didn't demonstrate any special talents here. What I do could have been done by anyone in the FreeBSD project, but I ended up managing the FreeBSD/EC2 platform by accident and now I'm the obvious person to keep on managing the platform.
Speaking from my (limited) project management experience, I found distributing tasks to the right person is actually a talent in itself.
Note: I was actually surprise how many people could not do it when I was trying to transition away into another project.
While the new C5 instances are certainly welcome - I've been hoping for their release since their announcement in November 2016 (and they were already late for Skylake at that point) - we have encountered a number of show-stopping problems that point to this project being just a bit too ambitious. To name a few: 1. EBS volumes attached to C5 instances show completely bogus CloudWatch metrics, over an order of magnitu…
So I wouldn't say C5s don't work at all with NLB instance target groups - I'm running one right now. I wouldn't be surprised if you're hitting an edge case with the tighter integration* between NLB's and instance associations. If you haven't already, please do reach out to support. * from the docs "If you specify targets using an instance ID, the source IP addresses of the clients are preserved and provided to your a…
