Subnets
When you create an RDS Postgres instance and add it to a VPC, the database requires that the VPC contains subnets in at least 2 different availability zones.
Go to subnets and create a new subnet.
Enter the VPC ID of the Datalogz VPC created in the VPC Deployment section.
Enter 10.0.0.0/25 as the IPv4 CIDR.
Choose an Availability Zone for the subnet.
Click Create Subnet.
Create at least two subnets in different Availability Zones. The RDS Postgres database requires that the VPC contains at least two subnets in different availability zones. Repeat the above steps to create another subnet with the following changes:
In step 3, enter the IPv4 CIDR as 10.0.0.128/25.
In step 4, choose a different Availability Zone than the one selected for the first subnet.
