What is Site Reliability Engineering (SRE)?
Site Reliability Engineering is an engineering discipline that applies software development principles to IT operations problems. The goal is to build scalable and highly reliable software systems through automation, monitoring, and continuous improvement.
SRE shifts the traditional operations model by empowering developers to take ownership of production systems, with a focus on:
Eliminating toil (manual, repetitive tasks)
Measuring reliability through SLOs and SLIs
Reducing incidents with proactive testing and automation
Enhancing collaboration between developers and operations teams
The SRE Foundation Certification formalizes these practices into an accessible training pathway, making them suitable for broad organizational adoption.
Who Should Pursue the SRE Foundation Certification?
This certification is designed for professionals involved in digital service delivery, operations, or DevOps practices. Ideal candidates include:
