Practice questions →Glossary →
  • 3.1Scalability and Elasticity

    Understand demand-following design—Auto Scaling (dynamic/predictive/scheduled), ELB, scaling policies (target-tracking/step), and lifecycle hooks. Scale automatically with load.

  • 3.2High Availability and Self-Healing

    Understand fault-tolerant design—Multi-AZ/Multi-Region, decoupling (SQS/SNS), self-healing (health checks + auto-replace), and Route 53 health checks/failover. Eliminate single points of failure.

  • 3.3Backup and Disaster Recovery

    Understand data protection and recovery—AWS Backup, snapshots, cross-region replication, and DR strategies (RTO/RPO). Recover reliably from failures and data loss.
