What is the difference between SRE and DevOps?

How much coding do SREs actually do?
A healthy SRE role is at least half engineering: building automation, tooling, and reliability features rather than manually firefighting. Google's rule caps operational toil at 50 percent. If an "SRE" job description reads like pure on-call ticket work, it is an ops role with a fashionable title.
