I have an Elastic Beanstalk app running on t2.medium with autoscaling enabled. EB automatically sets a default autoscale trigger of 6,000,000 bytes over a 5 minute period on NetworkOut. We have a meeting app, so many people load the page at the same time, this causes a spike of NetworkOut data for probably a 10 minute period.
The only place I can get info on what the bandwidth of a t2.medium instance is here:
EC2 instance types's exact network performance?
This says 250-300 MBit/s, which over 5 minutes is a much larger amount of data (~9Gb, unless my calculations are wrong).
I possibly incorrectly assumed EB would set a sensible figure for autoscaling but this seems miles out. Do you think it's safe to increase the autoscaling trigger to something closer to the available bandwidth?
