A Service Reliability Engineer (SRE) is a new role at many organizations, responsible for reliability of services. SREs are often developers who have taken on the additional responsibility of ensuring that the systems they build are reliable and scalable. They are also very familiar with the organization's service architecture and the dependencies of the services they manage.SREs focus on three main areas:1. Service Level Objectives (SLOs): SREs work with service teams to define and track SLOs. They also help teams identify and diagnose issues that are causing SLOs to be missed.2. Capacity Planning: SREs use data from monitoring and performance analysis to help teams plan for future capacity needs. They also help teams troubleshoot capacity issues when they arise.3. Incident Management: SREs help teams investigate and resolve incidents. They also work with teams to prevent incidents from happening in the first place by improving monitoring, alerting, and automation.
