Limitations

• Complex Setup: Advanced configurations can be complex and require expertise.
• Cost: Costs can increase with high query volumes and additional features like health checks.
• Learning Curve: Requires time to understand and effectively use all features and integrations.

Use Cases

• Global Application Deployment: Directing user traffic to the nearest AWS region for lower latency and higher performance.
• Disaster Recovery: Redirecting traffic to backup servers in case of a primary server failure using health checks.
• Load Balancing: Distributing traffic across multiple servers or regions to ensure even load distribution and improved application availability.
