SRE vs DevOps: 
Decoding the Key 
Differences - ClickIT 
Before getting into the SRE vs 
DevOps debate or a Site Reliability 
Engineer vs DevOps debate, it is 
important to define who a DevOps 
engineer is or what an SRE does. A 
DevOps engineer is an IT 
professional who possesses 
knowledge of software development, 
IT operations, and security to 
monitor and manage software 
development.
What is a Site Reliability 
Engineer (SRE)
Looking at the SRE vs DevOps 
discussion, one may think they 
are competing with each other. 
That is not true. A Site Reliability 
Engineer (SRE) doesn’t compete 
with a DevOps engineer, but 
they both complement each 
other. The concept of SRE was 
first introduced by Google in 
2003.
SRE vs DevOps: What are 
the key elements of a Site 
Reliability Engineer (SRE)
• Partnering with DevOps teams in designing and building 
software and systems, architectural design, automation, 
and security at the system/process level.
• Ensuring system reliability and availability while proactively 
implementing strategies for maintaining Mean Time to 
Recovery (MTTR) at the lowest possible level.
• Measure the performance of systems and monitor the 
infrastructure with a holistic view of the system’s health. 
• Proactively make changes for continual improvement of 
systems to align with the changing needs of customers.
• Fixing support escalation issues while empowering systems 
with self-healing abilities to reduce incidents.
