A Service Reliability Engineering Task is a technical operations task that enables service reliability engineering (supporting system reliability and operational excellence).
- AKA: SRE Task, Reliability Engineering Task, Site Reliability Task.
- Context:
- Task Input: system telemetry, performance metrics
- Task Output: reliability improvements, automated solutions
- Task Performance Measure: service level indicators such as availability metrics, latency metrics, and error rates
- ...
- It can ensure System Reliability through automation practices and monitoring solutions.
- It can maintain Service Level Objective through reliability engineerings and performance optimizations.
- It can implement Automated Process through infrastructure as code and continuous integration pipelines.
- It can establish Monitoring System through observability tools and alerting strategys.
- It can coordinate Incident Response through incident management processes and playbooks.
- ...
- It can optimize System Performance through capacity planning and scalability testing.
- It can enhance Knowledge Management through documentation systems and runbooks.
- It can secure System Infrastructure through security controls and compliance processes.
- ...
- It can range from being a Simple Automation Task to being a Complex System Engineering Task, depending on its infrastructure complexity.
- It can range from being a Basic Monitoring Task to being an Advanced Predictive Analysis Task, depending on its system requirements.
- ...
- Examples:
- Infrastructure Management Tasks, such as:
- Incident Management Tasks, such as:
- Performance Optimization Tasks, such as:
- ...
- Counter-Examples:
- Software Development Task, which focuses on feature development rather than operational reliability.
- System Administration Task, which emphasizes manual operations over automation engineering.
- DevOps Task, which covers broader development practices beyond reliability engineering.

- Site reliability engineering (SRE) is a set of principles and practices 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. Site reliability engineering is closely related to DevOps, a set of practices that combine software development and IT operations, and SRE has also been described as a specific implementation of Devops.

- Reliability engineering is the discipline of ensuring a system meets customer expectations for reliability throughout its life; i.e., it does not fail more frequently than expected. Next to prediction of failure, it is just as much about prevention of failure. Reliability engineering applies to all aspects of the system. It is closely associated with maintainability, availability (dependability or RAMS preferred by some), and logistics engineering. Reliability engineering is always a critical component of safety engineering, as in failure modes and effects analysis (FMEA) and hazard fault tree analysis, and of security engineering.
