What is the difference between SRE and DevOps?

Question

Could someone tell me what is the difference between SRE and DevOps?

Answer 1

Only slight differences exist between these two methodologies, one focuses on gradual implementation (DevOps), while the other focuses on releasing features fast by managing failure costs (Site Reliability Engineering). Well, let's get ahead with the differences between the two:

1. While both focus on reducing the gap between the development and operations team. DevOps focus on reducing silos (independently working teams or systems) whereas, SRE focuses on sharing the ownership with the developers, which allow them to use the same tools and procedures across the team.
2. DevOps team accepts failures, as they continuously develop and test their software, it’s quite natural for them. Whereas, SRE has a specific formula to balance failures with new releases.
3. SRE focuses on moving quickly, releasing new features fast but by looking at their production budget, that is they will validate how many failures they could take. And if they find that it's overshooting the budget, they will postpone the release until the problem has been fixed, which shows a lower rate of failure. On the other hand, DevOps implements gradual change, and release its features gradually.
4. DevOps intensively uses various tools and automation to get the workflow problems fixed. Whereas, in SRE team, they rely on Site Reliability Engineers to help prevent communication or workflow problems.
