# Deployment Options

> Cloud, BYOC, and Hybrid deployment models at Extend: managed US and EU hosting, BYOC inside your own VPC under your IAM and encryption policies, and Hybrid for in-country data residency.

Extend offers three deployment models with different tradeoffs on speed, control, and data residency. All models include enterprise security controls — see [Compliance](/security/compliance) for SOC 2, HIPAA, and GDPR coverage.

> **Note**
>
> **Summary.** Extend is not cloud-only. **Cloud** runs in Extend-managed US or EU regions (EU hosting in Frankfurt). **BYOC** deploys Extend into your own cloud account and VPC, under your IAM and encryption policies, so document data never leaves your environment. **Hybrid** keeps documents and application data in your cloud while inference runs in Extend's cloud. Extend does not currently offer a fully air-gapped deployment; BYOC uses your cloud provider's native AI services (for example, Vertex AI) inside your account.

|                        | **Cloud (Extend SaaS)**                  | **BYOC**                                                           | **Hybrid**                                             |
| ---------------------- | ---------------------------------------- | ------------------------------------------------------------------ | ------------------------------------------------------ |
| **Best for**           | Moving fast with minimal ops overhead    | Data sovereignty, regulated industries, existing cloud commitments | In-country data storage with managed AI infrastructure |
| **Where data lives**   | Extend-managed US or EU regions          | Your cloud account                                                 | Documents in your cloud; inference in Extend's cloud   |
| **Infrastructure**     | Fully managed by Extend                  | Deployed in your account; Extend manages setup                     | Split: app/data in your cloud, AI in Extend's cloud    |
| **Time to production** | Fastest — accounts provisioned and ready | \~2–3 weeks with guided provisioning                               | Faster setup than full BYOC; lower infra cost          |
| **GPU / AI ops**       | Managed by Extend                        | You provision GPU quota and cloud AI services                      | No GPU quota or model management on your end           |

## Cloud (Extend SaaS)

Extend manages all infrastructure, updates, and monitoring. Choose a region when you sign up:

| Deployment | Region | API                          |
| ---------- | ------ | ---------------------------- |
| **us1**    | US     | `https://api.extend.ai`      |
| **us2**    | US     | `https://api.us2.extend.app` |
| **eu1**    | EU     | `https://api.eu1.extend.ai`  |

See [Deployments](/api-reference/deployments) for SDK configuration and authentication.

**Why teams choose Cloud:**

* No infrastructure setup — get started immediately
* Extend handles scaling, updates, and security patches
* Subscription pricing with no infrastructure costs
* Proactive monitoring of application health and performance
* Inherit Extend's SOC 2, HIPAA, and GDPR certifications at the platform level

## BYOC (Bring Your Own Cloud)

Extend deploys into **your** cloud account so customer data never leaves your environment. You apply your existing IAM, VPC, and encryption policies while Extend handles deployment automation and application configuration.

**Why teams choose BYOC:**

* Data sovereignty and strict data-residency requirements
* Dedicated environment with no shared infrastructure
* Leverage committed cloud spend or reserved instances
* Flexible update windows scheduled around your operations

### What you provision

Extend's deployment automation handles networking, databases, storage, TLS, and application services. Your team typically provides:

* A dedicated cloud project with administrative access and a domain you control
* **GPU compute quota** — L4 instances for layout and reading order; H100 for table extraction and form parsing
* **Cloud AI services** — cloud-native OCR and LLM inference (for example, Vertex AI), with inference staying in your account
* **DNS delegation** — point your domain's nameservers to the cloud-managed zones Extend creates during deployment
* **SSO** — identity provider integration (Google Workspace, Okta, or Microsoft Entra ID)

### Infrastructure components

Deployed in your cloud account:

* **Extend application** — container orchestration
* **Database and cache** — PostgreSQL and Redis
* **Object storage** — documents and files
* **DNS and TLS** — domain and certificates
* **Identity** — SSO via Google Workspace, Okta, or Microsoft Entra ID
* **GPU compute, OCR, and LLM inference** — document AI models in your account
* **Extend BYOC controller** — deploys via service account

## Hybrid

Documents and application data stay in **your** cloud. AI models (GPU compute, OCR, LLM inference) run in **Extend's** cloud. Documents are sent to Extend for inference; results return to your environment.

**Why teams choose Hybrid:**

* Meets data-residency rules that allow processing outside the country while keeping storage in-country
* No GPU quota, model updates, or AI infrastructure to operate
* Faster setup and lower infrastructure cost than full BYOC
* Apply your IAM, VPC, and encryption policies to the customer-side deployment

Hybrid deploys the same customer-side components as BYOC (application, database, object storage, DNS, SSO) without provisioning GPU or cloud AI services in your account.
