Apparently for all the economic-related punditry, HN still doesn't understand economics. Jim, you do realize that "inflated" (relative term of course, since Uber is more expensive than taxis in some markets) is still part of the supply-demand curve, no? You absolutely have both. Go read a textbook before you chime in next time, k?
Well, there is a big difference, but not the one you've managed to come up with. Vagrant is normally used to run full VMs (although you can use it to drive Docker), so while you might run App, Supporting App, PHP, Apache, Node, Nginx, MySQL, Mongodb, and Redis all as separate containers, you'd probably put them all on the same VM. Your comment almost makes it sound like you don't understand Vagrant or VMs.
We half of all our QA processes to Fargate sometime around April, more than halved our compute costs. After the big summer milestone there is another big project to move the rest to Fargate. I prefer running my own k8s/kops cluster, but our B team got it stood up in a week and have had no issues in at least a quarter.
You are misinformed. Fargate is out and it works. I have containers running on it right now and they have been for several weeks now. You can select it or the old EC2 approach. Try it, you may like it.
And yes, knocking a 5-pound laptop down to 3 pounds is quite noticeable and a huge boon.
