What is job responsibitlity of site reliability engineer

A Site Reliability Engineer (SRE) is responsible for ensuring the reliability and availability of large-scale, distributed systems. Their job responsibilities typically include:

1. Monitoring and incident management: SREs monitor various systems and services to ensure that they are running smoothly. They are responsible for detecting and responding to incidents, which may involve troubleshooting issues and coordinating with other teams to resolve problems quickly.
   
2. Automation and tooling: SREs develop and maintain automation and tooling to improve the reliability and efficiency of systems and services. They may use scripting languages, configuration management tools, and other technologies to automate various tasks and workflows.
   
3. Capacity planning and scaling: SREs are responsible for planning and implementing capacity and scaling strategies for systems and services. They use various tools and techniques to monitor usage patterns and forecast future capacity needs, and they work with other teams to ensure that systems can handle increased traffic and demand.
   
4. Performance optimization: SREs optimize the performance of systems and services by identifying and addressing bottlenecks and other issues. They may use various monitoring and profiling tools to identify performance issues, and they work with other teams to implement solutions that improve system performance and efficiency.
   
5. Disaster recovery and business continuity: SREs plan and implement disaster recovery and business continuity strategies to ensure that systems and services can recover quickly in the event of a major outage or disaster.
   
6. Collaboration and communication: SREs work closely with other teams, such as development, operations, and security, to ensure that systems and services are reliable and available. They collaborate with these teams to share data, identify issues, and implement solutions.

Overall, the role of an SRE is to ensure that large-scale, distributed systems are reliable, efficient, and scalable. They are responsible for monitoring, automating, optimizing, planning, and collaborating to ensure that systems and services are available and performant.
