AWS Local Zones LA vs us-west-1 vs us-west-2, which is right for my LA store?

Three main AWS options for LA Magento, picked on latency + cost + features. AWS Local Zones LA (new, launched 2020+): a physical edge datacenter inside the LA metro itself, sub-10ms RTT from West LA to the Local Zone. Best for checkout-critical workloads (cart, payment, inventory) where every millisecond converts. Pricing premium ~20% over us-west-1. AWS us-west-1 (N. California / Bay Area): ~30ms RTT to LA. The default for most US-West Magento stores, cheapest, most services available, full RDS Aurora + ElastiCache + OpenSearch + Lambda + ECS. AWS us-west-2 (Oregon): ~50ms RTT to LA. Cheaper than us-west-1, more renewable energy. Most services available but compliance auditors prefer us-west-1 for CA data-residency. Our standard recommendation: hybrid, Magento app + DB on us-west-1 (cost), checkout + cart microservices on AWS Local Zones LA (latency), Cloudflare or Fastly CDN edge for static. For pure DTC under $5M GMV: us-west-1 alone is fine. For influencer-DTC with flash drops: Local Zones LA is worth the premium.
