The AWS Well-Architected Framework’s Reliability Pillar provides best practices for designing resilient workloads that can recover from failures and operate reliably over time. It emphasizes fault isolation, automated monitoring, and disaster recovery strategies to minimize downtime. Key principles include architecting for failure, automating recovery, and dynamically scaling resources. AWS services like Auto Scaling, Route 53, and CloudWatch enable proactive monitoring, failover management, and automated remediation. Organizations can improve system availability by deploying across multiple Availability Zones and Regions while implementing backup and recovery solutions. By following these best practices, businesses ensure high uptime, data integrity, and system resilience.
