Deploy Lambda + API Gateway to us-west-2; use Route 53 failover This is the ideal solution. Fully regional: deploy redundant infrastructure in us-west-2. Use Route 53 failover routing policy to direct traffic: If us-east-1 is healthy → traffic goes there. If us-east-1 fails → failover to us-west-2. Works with asynchronous workloads. Simple and reliable.

D, deploy everything in the second region and configure the failover routing policy
