Key Questions Answered
What tools does LinkedIn use for remote collaboration?
LinkedIn employs several tools for remote collaboration, including IRC for chat, BlueJeans for video conferencing, and inFormed for monitoring site changes. These tools help maintain effective communication and operational oversight across global teams.
How does LinkedIn ensure effective monitoring of site performance?
LinkedIn uses inFormed to track site activities, including deployments and feature releases. This tool provides a comprehensive feed of changes, allowing SREs to quickly identify issues and understand what has changed when problems arise.
What is the purpose of canary testing at LinkedIn?
Canary testing at LinkedIn involves deploying new code to a single host to compare its performance against control hosts. This method helps identify potential issues before a full rollout, ensuring stability and reliability in production environments.

Key Actionable Insights
1Utilize IRC for team communication to enhance collaboration and documentation.IRC allows for real-time communication and archiving of discussions, making it easier for team members to catch up on conversations and decisions made, especially in a remote work environment.
2Implement video conferencing tools like BlueJeans for remote meetings.Video conferencing helps bridge the gap between remote and in-office team members, facilitating better engagement during meetings and interviews, which is crucial for team cohesion.
3Leverage inGraphs for performance monitoring and alerting.Using inGraphs allows teams to visualize site performance metrics and set alerts, ensuring that they are promptly notified of any issues that may affect site reliability.
Common Pitfalls
1
Neglecting to utilize effective communication tools can lead to disconnection among remote teams.
Without tools like IRC or video conferencing, team members may miss critical updates or discussions, leading to misalignment and inefficiencies.
