Can you describe a scenario where you’ve used Amazon Route 53 alias records in a project and why you chose to use them?
In a recent project, we utilized Amazon Route 53 alias records to route traffic to an Elastic Load Balancer (ELB) and an S3 static website. The primary reason for choosing alias records was their ability to map domain names to AWS resources without requiring IP addresses.
Our application had two components : a web frontend hosted on an S3 bucket as a static website and a backend API managed by an ELB. We needed to route traffic from our custom domain to these resources efficiently.
We created two alias records in Route 53 : one pointing the root domain (example.com) to the S3 bucket and another pointing a subdomain (api.example.com) to the ELB. This allowed us to use friendly URLs while leveraging AWS infrastructure benefits like automatic scaling and failover.
Using alias records simplified DNS management, eliminated the need for manual updates when resource IPs changed, and provided latency-based routing for improved performance.
