Mission

Reliability Engineering teams are the gatekeepers and primary caretakers of the operational environment hosting all of GitLab's user-facing services (most notably GitLab.com), focusing on their availability, performance and scalability through reliability considerations.

Vision

Reliability Engineering team are composed of DBREs and SREs. As the role titles indicate, they have different areas of specialty but focus on the reliability of the environment as the unifying goal.

Reliability Engineering teams own the following operational processes:

• change management
• incident management
• delta management

The teams' overarching goal with respect to these processes is to outdate them through automation.

Key Metrics

Key metrics related to this group include:

• Uptime: of the operational environment at large and of services, subsystems and components.
• Incidents: alerts (including false positives), count, length (elapsed time), outages, escalations
• Deployments: count, length (elapsed time), “good” vs “bad”
• Efficiencies: manual vs automated tasks, (unexpected) interrupts

Team

Each member of the Site Reliability Team is part of this vision:

• Each team member is able to work on all team projects
• The team is able to reach a conclusion independently all the time, consensus most of the time
• Career development paths are clear
• Team creates a database of knowledge through documentation, training sessions and outreach
