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.

Find the Protocol Buffer Definitions in the /pb/ directory.
- 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.
See CONTRIBUTING.md
We meet weekly Monday's at 8:15 AM PT. The meeting is subject to change depending on contributors' availability. Check the OpenTelemetry community calendar for specific dates and Zoom meeting links.
Meeting notes are available as a public Google doc. For edit access, get in touch on Slack.
