Online Boutique is composed of microservices written in different programming languages that talk to each other over gRPC. Plus one Load Generator which uses Locust to fake user traffic.

- Kubernetes: the app is designed to run on Kubernetes (both locally , as well as on the cloud).
- Docker: this forked sample can also be executed only with Docker.
- gRPC: microservices use a high volume of gRPC calls to communicate to each other.
- OpenTelemetry Traces: all services are instrumented using OpenTelemetry available instrumentation libraries.
- OpenTelemetry Collector: all services are instrumented and sending the generated traces to the OpenTelemetry Collector via gRPC. The received traces are then exported to the logs and to Jaeger.
- Jaeger: all generated traces are being sent to Jaeger.
- Synthetic Load Generation: the application demo comes with a background job that creates realistic usage patterns on the website using Locust load generator.
- Prometheus: all generated metrics are being sent to Prometheus.
- Grafana: all metric dashboards are stored in Grafana.
