Physical location From the slide 10/58.
Region consists of multi AZs (Availability Zone) An AZ consists of AZ-a, AZ-b, AZ-c, etc. AZx (x=a,b,c) consists of data centers The latency within the Region is ~2ms.
Logical network VPC: A private network like 172.31.0.0/16 across AZs (AZa, AZb, AZc). VPC subnet: Each AZx is assiend a subnet, like 172.
Check your network When you deploy your docker container with port mapping, the network is automatically generated and the container assigned its own network.
