Backend Architecture

This backend exists to simulate real operational systems. It exposes live infrastructure state, not mocked data. Every response reflects production conditions.

API design

Serverless control plane

Requests are handled via API Gateway and Lambda using a stateless request model. The API is idempotent, horizontally scalable, and failure-aware.

Built to behave like production telemetry services.

API Gateway Lambda Stateless

Observability

Real infrastructure signals

Health checks, reachability tests, and metrics are pulled from real AWS services and made visible through a controlled API surface.

The same signals SREs rely on when on-call.

Route 53 CloudWatch Live data

Resilience

Failure propagation by design

Timeouts, upstream failures, and malformed responses are handled explicitly and returned cleanly to the UI without masking.

Fail loudly. Fail informatively.

Timeout handling Error clarity Predictable failure

Infrastructure

Provisioned entirely as code

All infrastructure business logic is encoded using Terraform including permissions, execution roles, and API routing.

No console drift. No snowflakes.

Terraform IAM CI/CD
