Site Reliability Engineering
Site Reliability Engineering (SRE) is a discipline that applies software engineering principles to operations and infrastructure problems to create scalable and highly reliable software systems. It focuses on automating tasks, managing service level objectives (SLOs), and balancing reliability with development velocity. SRE teams work to ensure that services are available, performant, and resilient to failures.
Developers should learn SRE when building or maintaining large-scale, distributed systems where uptime and performance are critical, such as in cloud-native applications or enterprise services. It helps reduce manual toil, improve system reliability through automation, and align operational goals with business needs by using metrics like error budgets. SRE is essential for roles in DevOps, cloud engineering, or any environment requiring high availability.
