I turned down a job offer with Amazon, partly because of their on-call rotation. They do not have a devops team, or even a unified tech stack. Each team is responsible for the creation, deployment and maintenance of their own code. I have dealt with too much shoddy legacy code in my lifetime, there is no way I will be woken up at 3am to support it. Many years ago, there was no devops/SRE. You had the developers and a sysadmin team if your company was big enough. The sysadmins did not know about anything at the application level, so developers were always on call. With the advent and the rise of the devops role, developers can now focus with their main task. I used Hadoop very early on (version 0.12 perhaps?), and I removed Hadoop as a skill on my resume since I did not want to admin a cluster, just do the cool MapReduce programming. Once again, devops to the rescue.
