Question
You are building a deployment system on AWS. You will deploy new code by bootstrapping instances in a private subnet in a VPC at runtime using UserData scripts pointing to an S3 zip file object, where your code is stored. An ELB in a public subnet has network interfaces and connectivity to the instances. Requests from users of the system are routed to the ELB via a Route53 A Record Alias. You do not use any VPC endpoints. Which is a risk of using this approach?
Options
- ARoute53 Alias records do not always update dynamically with ELB network changes after
- BIf the NAT routing for the private subnet fails, deployments fail.
- CKernel changes to the base AMI may render the code inoperable.
- DThe instances cannot be in a private subnet if the ELB is in a public one.
