STEP 4. Create
...
Subnets
https://ap-northeast-2.console.aws.amazon.com/vpc/home?region=ap-northeast-2#subnets:sort=SubnetId
- One for Availability Zone A, the other for Availability Zone B or C
...
Name | IPv4 CIDR | Availability Zone |
---|---|---|
PublicSubnet-az1 | 10.0.0.0/24 | az1 |
PrivateSubnet-app-az1 | 10.0.1.0/24 | az1 |
PrivateSubnet-db-az1 | 10.0.2.0/24 | az1 |
PublicSubnet-az2 | 10.0.3.0/24 | az3 |
PrivateSubnet-app-az2 | 10.0.4.0/24 | az3 |
PrivateSubnet-db-az2 | 10.0.5.0/24 | az3 |
STEP 5. Set Route Tables
https://ap-northeast-2.console.aws.amazon.com/vpc/home?region=ap-northeast-2#subnets2#RouteTables:sort=SubnetId
- One for App on Availability Zone A, the other for Availability Zone B or C
- One for DB on Availability Zone A, the other for Availability Zone B or C

STEP 7. Set Private Route Tables
1) Create Private Route Table and name it like "Private RT" for you
...
Name Route Table ID by "Elplicit subnet association" and "Main" like below:
Name | Explicit subnet association | Main |
---|---|---|
PublicRT | subnet-**** | No |
PrivateRT | Yes |
