AWS Network Load Balancer Lands in Phoenix Local Zone
AWS Network Load Balancer is now live in the Phoenix Local Zone (us-west-2-phx-2a), letting you keep your load balancing local instead of routing traffic back to the parent region. This means lower latency and faster connections for latency-sensitive apps like real-time gaming, media streaming, and live financial platforms serving Phoenix metro users.
