GraphQL/Zitadel/Kubernetes mail building blocks

[jhoninck]

We are experimenting/planning the use of pingoo with the following building block:

Client → WAF (HTTPS/TLS) → Connect RPC Gateway (HTTPS) → Zitadel (gRPC + TLS)
↓
GraphQL API (HTTPS) → PostgreSQL (TLS)

The building block is deployed numerous times as a service on kubernetes,
as is pingoo.

Zitadel serves as the single identity provider deployed on kubernetes, we have that part working soundly.
Including some tested units

All written in native RUST.

CRM application and BPMN applications will be served. Including social media links etc...

Because of the building block setup a high AI-supported setup will be used.

What is missing in pingoo is:

• OWASP references.
• gRPC references

Is this a sound approach ?

For mail it is the intention to use: https://stalw.art/ Also 100% RUST based
