    • Sets value goals, such as API latency thresholds, error rate limits, and uptime percentages.

    • Provides strategies for achieving these goals, such as caching, resource optimization, and load testing.

  2. Resilience and Fault Tolerance:

    • Focuses on maintaining service availability during failures or high loads.

    • Covers strategies such as multi-AZ deployments, retry mechanisms, and circuit breakers.

    • Highlights AWS services like DynamoDB Global Tables for data durability and SQS DLQs for error handling.

  3. Observability:

    • Explains how to gain real-time insights into system behavior and dependencies.

    • Describes tools like AWS X-Ray, CloudWatch ServiceLens, and OpenSearch Dashboards for distributed tracing, log aggregation, and dependency health monitoring.

    • Provides actionable insights into request flows, anomaly detection, and system utilization trends.

  4. Incident Response:

    • Details processes for efficient issue detection, alerting, and resolution.

    • Outlines tools like CloudWatch Alarms, SNS Notifications, and AWS Systems Manager for automated recovery actions and notification workflows.

    • Includes runbooks and postmortem reviews to improve incident handling.

  5. Performance Optimization:

    • Covers strategies for improving throughput and reducing latency across services.

    • Describes how to use ElastiCache, OpenSearch, and auto-scaling to optimize performance.

    • Includes AWS services and techniques for caching, indexing, and monitoring query execution times.

  6. Disaster Recovery (DR):

    • Explains how to implement robust DR plans to ensure data availability and minimal downtime during disasters.

    • Highlights cross-region replication with DynamoDB Global Tables and automated failover using Route 53.

    • Provides DR testing methodologies to validate recovery strategies.

  7. Capacity Planning:

    • Discusses how to scale services dynamically to handle traffic growth.

    • Describes the use of auto-scaling for ECS tasks, DynamoDB tables, and other resources.

    • Covers stress testing and resource utilization monitoring to predict capacity needs.

  8. Security and Compliance:

    • Focuses on protecting data and ensuring compliance with security standards like GDPR and PCI DSS.

    • Details security practices, including IAM least privilege policies, data encryption with KMS, and network isolation with VPC endpoints.

    • Explains how GuardDuty and Security Hub are used for continuous compliance and threat detection.

  9. Cost Management:

    • Explains cost-saving strategies while maintaining service quality and performance.

    • Includes techniques like DynamoDB on-demand scaling, S3 Intelligent-Tiering, and using Spot Instance for batch processing.

    • Encourages proactive cost monitoring with tools like AWS Budgets and Trusted Advisor.

  10. Continuous Improvement:

    • Encourages regular reviews and feedback loops to refine SRE practices.

    • Explains how to use tools like the Well-Architected Tool and CloudWatch Dashboards to identify improvement areas.

    • Focuses on rolling out updates and feature enhancements through CI/CD pipelines.
