Site Reliability Engineering
Site Reliability Engineering (SRE) is a discipline that applies software engineering principles to operations and infrastructure tasks to create scalable and highly reliable software systems. It focuses on automating operational processes, measuring system performance, and balancing reliability with development velocity. SRE teams are responsible for availability, latency, performance, efficiency, change management, monitoring, emergency response, and capacity planning.
Developers should learn SRE when building or maintaining large-scale, distributed systems that require high availability and resilience, such as cloud-native applications, microservices architectures, or critical business platforms. It is essential for organizations aiming to reduce manual toil, improve system reliability through automation, and foster collaboration between development and operations teams. SRE principles help prevent outages, optimize resource usage, and ensure consistent user experiences.
