SREPraktiken

SREPraktiken, an abbreviation for Site Reliability Engineering Practices, refers to a set of principles and methodologies that blend software engineering and operations to build and manage scalable, highly reliable software systems. The core idea is to apply software engineering approaches to infrastructure and operations problems. This involves defining service level objectives (SLOs) and service level indicators (SLIs) to measure the reliability of services and then using error budgets to guide the balance between introducing new features and maintaining stability.

Key SREPraktiken include automation of manual tasks, such as provisioning, configuration, deployment, and incident response. This reduces toil, the repetitive, manual work that engineers perform. Monitoring and observability are paramount, with a focus on collecting comprehensive metrics, logs, and traces to understand system behavior and quickly detect and diagnose issues. Incident management is another critical aspect, emphasizing rapid response, effective postmortems, and learning from failures to prevent recurrence.

While originating at Google, SREPraktiken have been widely adopted by organizations of all sizes seeking to improve the availability, performance, and efficiency of their services. The discipline encourages a shared responsibility model between development and operations teams, fostering a culture of collaboration and continuous improvement. Ultimately, SREPraktiken aim to achieve a desired level of reliability in a cost-effective manner, ensuring that user experiences are consistently positive.
