Design Principles for Operational Excellence
Perform operations as code to reduce errors and create predictable responses through automation.
Treating the entire workload as software, turning operations into scripts, and automating them reduces human error and ensures predictable outcomes when specific events occur.
Make frequent, small, reversible changes to quickly address issues without major customer impact.
The principle encourages making changes in small, manageable steps that can be easily undone if problems arise, allowing for rapid issue resolution with minimal disruption to users.
Refine operation procedures frequently to evolve with the workload and streamline processes.
Continuously improve and streamline operational procedures as the workload changes and evolves over time, always seeking better ways to perform tasks.
Anticipate failure by identifying potential issues before they occur and testing response procedures.
Proactively identify potential failures before they happen and regularly test scenarios to understand their impact, ensuring that response procedures remain up-to-date and effective.
Learn from operational failures by using every event as a chance to build stronger, more resilient systems.
Treat every operational event or failure as a learning opportunity. Use these lessons to enhance system strength and resilience, and share this knowledge across teams for collective improvement.
Design Principles for Reliability
Automatically recover from failure by closely monitoring metrics and using automation for rapid issue resolution.
Monitor key metrics closely and implement automation to fix issues as soon as they arise, enabling the system to automatically recover from failures and minimize downtime.
Test recovery procedures regularly using automation to simulate failure scenarios and validate plans.
Actively test how the system handles failures in practice by using automation to simulate frequent failure scenarios, ensuring that recovery plans are effective and function as intended.
Use horizontal scaling to increase aggregate workload availability by spreading tasks across multiple resources.
Distribute workloads across multiple smaller, independent resources. This approach ensures that if one resource fails, the entire workload is not impacted, thereby increasing overall availability.
Stop guessing capacity by accurately monitoring usage and adjusting resources precisely as needed.
Accurately monitor system utilization and adjust resources dynamically to match the exact demand, avoiding over-provisioning or under-provisioning.
Manage change through automation to ensure consistency, trackability, and smooth operation of infrastructure changes.
Automate all changes to the infrastructure. This method helps maintain consistency, makes changes easily trackable, and ensures smooth ongoing operations.
