Serverless end to end
API Gateway takes the request, Lambda resolves it, DynamoDB stores the mappings. There is no server to patch, and the whole thing scales to zero when idle.
IaC : Infrastructure as code
Every resource is provisionned in Terraform. The entire stack can be destroyed and rebuilt from scratch with Terraform commands.
Least-privilege IAM
Each component gets exactly the permissions it needs, and nothing more. That's the point of least privilege. A compromised Lambda can't touch resources it was never scoped to reach in the first place. It takes more upfront work than attaching a broad managed policy, but it shrinks the blast radius if anything ever goes wrong.
Built to cost nothing at rest
The whole stack is serverless and billed pay-per-request, so it idles for free. Lambda only spins up when a link is actually resolved, runs for a few milliseconds, and then shuts back down. No servers sitting around waiting for traffic.
