Ask HN: What software of the 2010's significantly changed how you program?

I was just spinning up a NodeJS Docker on AWS today and it occurred to me that just 10 years ago I was still installing LAMP images behind an Nginx LB on physical servers... I was amazed at how radically different being a full stack dev is today compared to back then (...in fact my first corporate project was a ColdFusion server in 1996, which I've mostly forgotten about intentionally).

I'm smitten with the big compute cloud providers and Docker, one of which was in its infancy in pre 2010, and the other did not exist at all.

What tech really made your life easier in the 2010s?

Bonus Q: By 2030, what big software disruption do imagine will have occurred in the 2020's?
