Site Reliability Engineering

Site Reliability Engineering (SRE) is a discipline that incorporates aspects of software engineering and applies them to infrastructure and operations problems. The main goals are to create scalable and highly reliable software systems.

This section covers various SRE topics, practices, and personal experiences implementing SRE principles.
