It's highly available so you don't need redundancy in an AZ, and you can share them between your AZs. However if you want really high availability you can create one per AZ. Which I interpret as: As long as the whole AZ is not down, AWS guarantees HA for NATGW (possibly with service interruption or degradation). Technically you should be good with a single NAT GW in any one of your public subnet as long as the rout table of all 3 private subnets provide a route to this NATGW (and implicit I guess but security-group/acl are configured to allow use of that route). Para crear y configurar NAT Gateway, vamos al servicio VPC —> NAT Gateway —> Create NAT gateway Se abrirá la ventana de configuración y le pondremos un nombre, seleccionaremos una subred publica y haremos clic en Allocate IP Elastic para que nos cree y nos asigne una IP Elástica. Apart from HA, the above architecture also provides better overall throughput, since during normal conditions, both NAT Instances can be used to drive the outbound internet requirements of the VPC. To create an Availability Zone-independent architecture, create a NAT gateway in each Availability Zone and configure your routing to ensure that resources use the NAT gateway in the same Availability Zone." So if i have 2 public subnets a and b, and 1 private subnet c, my Nat GW for private subnet c needs to be in public subnet a (or b).

Components NAT Gateway. The NAT Gateway is a component part of the Virtual Private Cloud (VPC) solution offered by AWS. As an important component that is, the NAT gateway has the ability and is A Nat Gateway is an AWS resource that is like a NAT instance in terms of functionality but it’s a lot easier to manage and highly available within an Availability Zone. To allow instances within a private subnet to access Internet resources via a NAT gateway, you must do the following: set up a nat gateway for each private subnet in each availability zone. Depending on location this amounts to around 30$ per subnet per availability zone. With 3 availability zones and 2 subnets this will total to around 180$ a month, which is actually more than we plan to use for the ec2 instances while there is not much traffic and load on # together with a NAT Gateway and associated routing.
