Application architecture

The following architecture depicts the components and dependencies that make up the appplication and their relationships.

Components

Component	Type	Technology	Internal to Internal	External Ingress	Internal Dependency	External Dependency	Optional Sidecars
Bosun	Front End	React + Node.js	Bosun MS	true
Policy	Microservice	Spring Boot (Java)	Repository MS	true	MongoDB, OpenPolicyAgent		New Relic APM
Repository	Microservice	Spring Boot (Java)		false	SonarQube, JFrog XRay		New Relic APM
OpenPolicyAgent	Middleware	Go		false

Notes:

1. Optional sidecars are what is known at the application layer. This does not include any DaemonSets defined at the Infrastructure and Orchestrator layer.
2. Repository microservice is not required to be integrated to the dependencies. This is required only if you used the predefined integrations, as opposed to passing in an already retrieved payload.
3. OpenPolicyAgent is a third-party open source component that Bosun wraps.
