Kubernetes / Platform Design

Solution DesignBuilt on top of Managed Kubernetes

Multi-Tenant Kubernetes Platforms

Your managed Kubernetes cluster is the foundation. On top of it, we design multi-tenant platforms tailored to your organization — with isolated tenants, automated governance, and a unified tenancy toolkit.

Multitenancy & Isolation

Namespace-level isolation with RBAC, quotas, network policies, and pod security. Each team gets its own blast radius.

Smart Guardrails

Policy-as-code via Kyverno, admission control, image policies, and audit logging. Compliant by default, not by effort.

Unified Tenancy Toolkit

A single Helm chart that renders all tenant resources — namespaces, policies, secrets, registries, and RBAC. ArgoCD syncs to the cluster, and optional operators handle custom lifecycle needs.

Multi-Tenant Architecture

We design a layered architecture on top of your managed cluster — separating onboarding, authentication, tenant isolation, policy enforcement, platform services, and observability.

Tenant Provisioning

Once your managed cluster is running, the next challenge is multi-tenancy. We design a provisioning layer on top — so onboarding a new team doesn't mean weeks of tickets.

ArgoCDSyncs to cluster

We design and integrate a Tenant Helm chart tailored to your organization that renders all required resources from one values.yaml. ArgoCD syncs the rendered manifests to the cluster. For custom lifecycle needs, we build specific operators on top:

Secrets Management

ClusterSecretStores and Vault paths per tenant, rendered automatically

Container Registry

Registry projects with dedicated pull secrets and image policies

Network Policies

Cilium-based namespace isolation, configured via Helm values

Kyverno Policies

Per-tenant admission rules, image allow-lists, resource limits

Monitoring

Tenant-scoped dashboards, alerts, and log aggregation

ArgoCD continuously reconciles the desired state. If something drifts — a policy is deleted, a secret is misconfigured — it detects the deviation and syncs back to the Helm-rendered baseline automatically.

GitOps with Smart Guardrails

Every change goes through Git. ArgoCD syncs, Kyverno validates — compliant by default, not by effort.

Self-Service Onboarding

We design the onboarding flow so new teams go from definition to operation in minutes, not weeks.

1

Define

Platform team configures a tenant values.yaml: namespaces, quotas, RBAC, network policies, secrets, registry access.

2

Deploy

GitOps pipeline picks up the change. ArgoCD renders the Helm chart and syncs all tenant resources to the cluster automatically.

3

Operate

Teams self-serve within their guardrails. ArgoCD watches for drift and ensures the cluster matches the desired state defined in Git.

A new team is a pull request, not a support ticket.

In Practice: Multi-Platform Container Architecture

The solution design applies across deployment models. Same tenant Helm chart and guardrails, wherever your workloads run.

Shared Platform Services

RegistrySecretsGitOpsObservability
1

One Tenancy Model

Same Tenant Helm chart works across Natron Cloud, Flex Stack, and BYOC. Platform-specific configuration via values toggles — operators available as add-ons where needed.

2

Centralized Registry

Single container registry serves all platforms. Flex Stack and BYOC clusters pull images remotely — no duplication.

3

Environment Parity

Test, integration, and production clusters follow identical architecture. Promote with confidence.

4

Network-First Design

Non-overlapping address spaces across all clusters. Built for future cross-cluster connectivity.
