SRE stands for Site Reliability Engineering, which is a software engineering discipline that concentrates on building and maintaining complex systems that are reliable, scalable, efficient, and resilient. It combines aspects of software engineering and operations to enable organizations to deliver reliable and efficient services to their customers.
SRE focuses on automating tasks, monitoring, and managing large-scale systems to enhance their availability, performance, and fault tolerance. It emphasizes on creating reliable systems from the beginning rather than reacting to failures post deployment. SRE teams work closely with developers to ensure that applications are designed to meet reliability requirements.
The role of an SRE professional involves tasks such as system design, capacity planning, incident response, performance analysis, and troubleshooting. They develop tools and implement best practices to automate and streamline operations, reducing manual intervention and human error.
SRE is rooted in the principles of DevOps, sharing similar goals of collaboration and automation. However, SRE focuses specifically on system reliability and resilience, bringing engineering practices to operations and infrastructure management.
SRE teams aim to achieve a balance between system reliability and development velocity, providing maximum service availability while enabling frequent iterations and feature deployments. They are responsible for establishing and measuring service-level objectives (SLOs) to ensure continuous improvement and delivering excellent user experiences.
Overall, SRE is a methodology and practice that blends software engineering and operations principles to build, maintain, and enhance highly reliable and performant systems.
