Curious if the need for pre-warming ELB/ALB still applies. Last time this came up, an AWS employee mentioned it is no longer necessary (https://news.ycombinator.com/item?id=14052079), but would be nice if this was documented.
I don't want to dox myself but about a year ago when my employer forgot to notify AWS about switching our production traffic (about 5K rps at that time) from one ELB to another we failed requests for several minutes before we decided to just switch back to the old ELB then ask them to do a prewarming before we switched again.
The "advance notice" and "over provision" advice is still being given for things that could scale up fairly large. (where fairly large isn't anything that exciting, really)
