# Concepts

> Get up to speed on BYOC and Nuon.

Nuon is built around three pillars: connecting your product to Nuon as an app template for BYOC delivery, customer installs, and enabling continuous delivery. This section covers the core concepts behind each.

## Connect Your App

Everything you define as a vendor to package your application for BYOC delivery.

> **[Nuon App Templates](https://docs.nuon.co/concepts/apps.md)**
>
> Point an app template at your application code and infrastructure to make versioned, installable BYOC products.

> **[Components](https://docs.nuon.co/concepts/components.md)**
>
> Wire up Helm charts, Terraform modules, Kubernetes manifests, and container images.

> **[Sandboxes](https://docs.nuon.co/concepts/sandboxes.md)**
>
> Define the base infrastructure layer provisioned in each customer's cloud account.

> **[Inputs](https://docs.nuon.co/concepts/app-inputs.md)**
>
> Customer-supplied values — region, instance type, API keys — that configure each install.

> **[Secrets](https://docs.nuon.co/concepts/app-secrets.md)**
>
> Manage sensitive values like credentials and API keys used in app configuration.

> **[App Variables](https://docs.nuon.co/concepts/app-variables.md)**
>
> Store and share dynamic values across all installs of an app via the API.

> **[Runners](https://docs.nuon.co/concepts/runners.md)**
>
> Egress-only agents that deploy and manage installs inside customer cloud accounts.

## Customer installs

Deploy into customer cloud accounts and adapt to their existing infrastructure.

> **[Installs](https://docs.nuon.co/concepts/installs.md)**
>
> Deployments of your app template running in a customer's cloud account.

> **[Stacks](https://docs.nuon.co/concepts/stacks.md)**
>
> Cloud-native templates that bootstrap an install in a customer's cloud account.

> **[Operation Roles](https://docs.nuon.co/concepts/operation-roles.md)**
>
> Map IAM roles to specific operations for least-privilege access in customer accounts.

## Continuous Delivery

Push updates with governance, audit trails, and operational control.

> **[Workflows](https://docs.nuon.co/concepts/workflows.md)**
>
> Orchestrate the deployment, update, and teardown lifecycle of apps and components.

> **[Actions](https://docs.nuon.co/concepts/actions.md)**
>
> Run operational scripts for health checks, migrations, and day-2 operations.

> **[Policies](https://docs.nuon.co/concepts/policies.md)**
>
> Enforce compliance and security rules across builds and infrastructure deployments.

> **[Triggers](https://docs.nuon.co/concepts/triggers.md)**
>
> Route external webhook events to app branch runs and install runbooks.

> **[API Tokens](https://docs.nuon.co/concepts/api-tokens.md)**
>
> Org-scoped tokens for authenticating to the Nuon Control Plane API.

> **[Service Accounts](https://docs.nuon.co/concepts/service-accounts.md)**
>
> Named machine identities for automation, CI/CD, and runners.
