What is stress load testing then? Most large companies do perform something to this.... Most large companies do some stress load testing first for any new system. Then they release to few percent of the users (less than 10%) and gradually increase to the rest of the userbase. I worked at Spotify, when Tidal was launched. They had failed to do proper capacity testing, and the service failed under the load the first week and it showed. But most mature large company tend to be really good on this. It is remarkable how many tech companies have managed to stay mostly up with very few outages, given this whole pandemic situation, where everybody is online. I'd say working in large scale deployment is proper engineering .... creating a simple webpage, maybe not. Deploying that webpage to millions of users, it is. Also, don't forget that bridges have been made since the dawn of time, while tech and the internet are very very young in human terms.

I must admit that it was very gratifying watching all our engineering decisions pay off when our system started seeing record high traffic every day and scaled effortlessly and with no outages - the traffic that came with lockdown is, even on our slower days, twice our planned for and tested for high water mark. But it took us about 4 years of consistent effort in changing our organisational mindset all the way through, devs, testers, product managers, c-suite members, to get here. 4 years ago, we would've been waking everyone up and going without sleep for a couple of days trying to get something back online, then fixing the next system down the line that failed because of the load, then the next one, and then writing long post-mortems for our business team.
