• SRE observations help them calculate the potential cost of outages and plan for contingency.
• SRE usually split their time between operations and the development of systems and software.
• SRE spent time on building and deploying services that optimize the workflow for IT and support departments.
• SRE determine what new features can be implemented and when this is possible through the help of SLAs, SLIs, SLOs.
• Service Level Agreements (SLAs), Service Level Indicators (SLI), and Service Level Objectives (SLO).
