“SRE is what you get when you treat operations as if it’s a software problem. Our mission is to protect, provide for, and progress the software and systems behind all of Google’s public services — Google Search, Ads, Gmail, Android, YouTube, and App Engine, to name just a few — with an ever-watchful eye on their availability, latency, performance, and capacity.”

From the definition of the SRE above, the key words are

Software and system

availability, latency, performance, and capacity

The system or the infrastructure in this case could be private cloud, public cloud or the servers in data centers. A Site Reliability engineer works to ensure the systems are

  • always available,
  • the latency is within the acceptable levels,
  • the performance is as per the SLA and
  • the Capacity usage is within the acceptable thresholds.

So, a Site Reliability should have the expertise of Server technologies, Cloud platform, expertise in using tools/techniques to measure latency, SLA, monitor capacity usage etc.


DevOps is the new age methodology followed to deploy software on the systems. And hence it makes sense for a Site Reliability Engineer to be aware of the DevOps concepts and tools.
