System Architecture

Zinorel Cloud Platform Architecture

How ZINOREL (PVT) LTD architects high-concurrency systems, fine-grained access control, and strict multi-tenant data isolation.

Explore how our services, authorization, and data isolation mechanisms collaborate.

100% Invariant Enforcement

Ingress & Gateway

1. Edge & Ingress Layer

Every incoming client request (Web, Mobile, External API) reaches our Envoy-based API Gateway. It terminates TLS, validates JWT tokens, extracts tenant context, and enforces rate limits before routing to internal services.

Autonomous Services Mesh

Every service owns its domain schema, business rules, and state boundaries.

Row-Level Data Sovereignty

Multi-tenancy is enforced directly at the storage engine. Strict database policies guarantee that queries cannot leak data across tenants or instances.

Transactional Outbox Pattern

Every business state mutation and its corresponding event are committed atomically in the same database transaction, guaranteeing reliable event delivery.

Declarative Delivery

Production infrastructure is declared as code. Git commits trigger automated pipelines that reconcile and self-heal workloads automatically.
