Architectural Plans

Represents a TODO list of what I want from this project ideally. Every section provides a high to low level requirements.

todo: create proper sections

Reactive Manifesto compliance
Security, Google login
✅ UI
✅ GraphQL API
✅ Event Sourcing & CQRS
- ✅ Separate write domain model populating Event Storage
- ✅ Separate read domain model for each use case building from the Event Storage into NoSQL
Maybe Graph/Key-Value databases, cache, distributed locking for interesting use cases
✅ No external services for local/test runs, i.e. all storage is in-memory etc
✅ Reactive programming end to end
CI
Actual live webpage
CD - containerized deploy configuration
Monitoring

Tech stack:

✅ Kotlin
✅ Spring all the way: WebFlux, Boot, Data, Security, etc
✅ UI: Vaadin.
- Chose Because I don't know UI stack and this just uses Java. Might go for an actual front end if have enough time/will to learn
✅ GraphQL-Java module with Kickstart Spring Boot project
- todo Wait for / contribute RSocket support
✅ Event Sourcing & CQRS abstraction: Axon Framework
Axon Server CE as Event Storage and Messaging all-in-one solution
✅ MongoDB
✅ docker-compose.yml for one-click local run
CircleCI or similar
Sonar Cloud as a static analysis tool
✅ Automatic code formatting config
Docker and/or Kubernetes and/or CloudFoundry configurations
Cloud provider: Pivotal/AWS/Google/Azure/Heroku depends on price
Open Tracing Jaeger
Micrometer as a metrics framework, can export to a lot of places
Dashboard solution: DataDog/Prometheus/AWS CloudWatch/Azure Monitor/New Relic depends on price
