AWS Resiliency and High Availability Report

Overview

This report assesses your AWS environment for resiliency and high availability (HA) best practices. It evaluates whether critical infrastructure is distributed across availability zones (AZs), protected from accidental deletion, and properly configured for failover.

Ensuring a resilient architecture helps:

• Minimize downtime during outages or infrastructure failures
• Reduce impact from misconfigurations or human error
• Meet business continuity and disaster recovery (DR) requirements
• Improve compliance with SLA and HA design standards

Each finding includes resource-level results with guidance for improving system availability.
