Amazon ECS is now available in the Los Angeles AWS Local Zones
You can now run Amazon Elastic Container Service tasks in the two AWS Local Zones in Los Angeles. With Amazon ECS/EC2 on Local Zones, you can run latency-sensitive applications closer to end-users in Los Angeles. Once you have opted in for using AWS Local Zones, you can create a VPC and subnet in the local zone to deploy EC2 resources into it and attach them to your ECS clusters in AWS US West (Oregon) parent region.
