Disaster recovery using Devops

I am new to Devops.
I come from traditional Unix admin role with 15 years experience . I am AWS and Azure certified.
I am trying to understand devops and get that it is a definite process for application development.

But I wanted to know more as in what is done in day to day tasks by devops Engineers. Some say that Devops is more specific and closer to containerized application development on clouds and containers.

Is life of devops engineer more like that of infra support or application support ?
