This repository contains a collection of example applications for the Nais platform. The main example is a Quotes application, where users can view and create quotes. Each service demonstrates a specific technology stack and integration pattern commonly used in modern cloud-native applications on Nais.
Another key purpose of these examples is to showcase the observability features available in the Nais Platform, based on OpenTelemetry. This includes:
- Logs collected in Loki
- Metrics collected in Prometheus
- Traces collected in Tempo
All observability data is available and visualized in Grafana, making it easy to monitor, debug, and understand your applications running on Nais.
The purpose of this repository is to help developers understand how to:
- Build and deploy frontend, backend, and load generation services on Nais
- Integrate with managed databases (PostgreSQL)
- Use modern frameworks and best practices for cloud applications
This repository consists of the following services:
| Service | Tech Stack | Purpose & Description |
|---|---|---|
| quotes-frontend | Next.js, React, Tailwind CSS | The web frontend for the Quotes app, allowing users to view and submit quotes. |
| quotes-backend | Kotlin, Ktor, PostgreSQL | The backend API for the Quotes app, handling quote storage and retrieval. |
| quotes-loadgen | Go (Golang) | A load generator for simulating traffic and testing the Quotes application. |
For more details on each service, see the README in the respective subdirectory:
