Following diagram outlines the high level architecture of UniResource.
User authentication and authorization as well as user and tenant management is outside of UniResource. UniResource is typically deployed behind an api-gateway that handles authentication and authorization relying on an external Identity Managmenet system.
The only aspect of tenancy management that needs to be handled by UniResource is: per tenant database creation and removal. Each tenant has its own database in database server.
This section provides details on intended technologies to develop UniResource with.
UniResource will rely on technologies used by the Inventory project currently residing at: https://github.com/facebookincubator/magma since both projects are similar and have similar requirements.
Ent is an ORM framework for go
Also handles schema migration: creates or updates tables in DB according to ent schema
RBAC rules can be defined as part of the schema
PSQL is the DB of choice, but thanks to ent framework hiding the interactions with the database, other SQL DB could be used in the future
Primary API of UniResource will be exposed over GraphQL (over HTTP)
Gqlgen is a graphql framework for go
Works well on top of entgo.io ORM
Web assembly runs any user defined code executing allocation logic for user defined resource pools
Isolated and limited for safety and performance
Tenant and user management is out of scope of UniResource and will be handled by an external identity management system.
