Explanation

For achieving high availability (99.5% uptime or higher) for a crucial ecommerce application, deploying across multiple AWS Regions is the correct strategy because:

Multiple Regions provide geographic redundancy: If one entire region experiences an outage, the application can failover to another region, maintaining availability.
Higher availability SLAs: Multi-region deployments can achieve higher availability than single-region deployments.
Disaster recovery: Multiple regions provide true disaster recovery capabilities.

Why not multiple VPCs?

Multiple VPCs within the same region still share regional infrastructure dependencies
Regional outages would affect all VPCs in that region
While multiple Availability Zones within a region can provide good availability, multi-region provides even higher resilience

Best Practice: For mission-critical applications requiring 99.5%+ uptime, a multi-region deployment strategy with proper failover mechanisms is recommended.
