   • AUse Amazon CloudFront with the existing ALB as the origin, and cache static content at edge locations.
   • BCreate VPC peering connections between all regions and route traffic through a central hub.
   • CUse AWS Transit Gateway with inter-region peering to connect all regional VPCs.
   • DDeploy ALBs in each region and use AWS Global Accelerator to route traffic to the nearest healthy endpoint.
