# Overenginner Microservices Summary
* `health-api`: REST Interface for product. Using API Composition pattern.
* `bmr-grpc`: gRPC Microservice to calc Basal Metabolic Rate
* `imc-grpc`: gRPC Microservice to calc IMC
* `recommendations-grpc`: gRPC Microservice to summarize diet recommendations and contabilize Macros
* `proteins-grpc`: gRPC Microservice to calc daily protein necessity
* `water-grpc`: gRPC Microservice to calc daily water ingestion
* `calories-grpc`: gRPC to calc calories ingestion necessity
* `health-data-offload`: Worker to save health-reports on data layer
* `frontend`: VueJS SPA

# Jaeger and Zipkin
## Using Tracing between services
To use jaeger tracing with zipkin you can specify environment variable called `ZIPKIN_COLLECTOR_ENDPOINT`.
```bash
export ZIPKIN_COLLECTOR_ENDPOINT=http://jaeger:9411/api/v2/spans
```
# TODO
* Refactor communication lib
* Customize log lib for trace id
* Error Handling and Retries
* Implement Prometheus HTTP Endpoint
* Create Kubernetes Deployment
* Create Istio Manifests to Service Mesh gRPC Optimizations
## Notes
