Local Zones have some attributes that we need to take notes expecially when we need to create EIP or RDS. Below some explainations: Command:    aws ec2   describe-availability-zones --filters "Name=zone-type,Values=local-zone" --region ap-southeast-1 Above is using Bangkok Local Zone ZoneName : This property can be use when we want to create subnet in Local Zone GroupName : I t is use to group all the local zones available in that place\area.  Note: The picture above i am using us-west-2-lax (LA) because Bangkok only have 1 Local Zone.

What is Local Zones? a. It is an extention of availability zone to those country where AWS do not have region in. b. Design to get closer to customer hance, enhancing latency or/and data residency due to compliances. Setup: 1. Enable Local zones, first select the region you want to connect your local zone. In this example, my region is Singapore (ap-southeast-1) and therefore enable local zone in Thailand: a. https://ap-southeast-1.console.aws.amazon.com/ec2/home?region=ap-southeast-1#Settings:tab=zones b.  c. Create VPC in ap-southeast-1 d. create Subnet in Local Zones That it for quick start in AWS Local Zones.
