# CockroachDB BYOC Overview

export const InternalLink = ({version, path = "", children, ...props}) => {
  let detectedVersion = version || "stable";
  if (typeof window !== 'undefined' && !version) {
    const match = window.location.pathname.match(/\/docs\/([^/]+)/);
    if (match) {
      detectedVersion = match[1];
    }
  }
  const normalizedPath = path.startsWith("/") ? path.slice(1) : path;
  return <a href={`/docs/${detectedVersion}/${normalizedPath}`} {...props}>
      {children}
    </a>;
};

CockroachDB CockroachDB Cloud supports a [Bring Your Own Cloud (BYOC) deployment model](https://www.cockroachlabs.com/product/cloud/bring-your-own-cloud/), where CockroachDB CockroachDB Cloud Advanced is hosted in your own cloud account rather than in an account managed by Cockroach Labs. This model allows you to take more control of security and take advantage of existing cloud service credits or discounts.

## Shared responsibility model for BYOC

In any CockroachDB CockroachDB Cloud deployment, responsibility for a successful and healthy deployment is <InternalLink path="production-checklist">split between you and Cockroach Labs</InternalLink>. In a BYOC deployment, all of the <InternalLink path="plan-your-cluster-advanced#advanced-cluster-architecture">CockroachDB CockroachDB Cloud infrastructure</InternalLink> except the control plane lives in an account under your control, which means that you incur additional responsibilities under the shared model.

The following table describes the split of responsibilities between you and Cockroach Labs in the shared responsibility model for BYOC:

## Next steps

CockroachDB supports BYOC deployments in Amazon Web Services, Microsoft Azure, and Google Cloud Platform. To prepare your cloud account for a BYOC deployment, refer to the corresponding deployment guide:

* <InternalLink path="byoc-aws-deployment">Prepare a CockroachDB Cloud BYOC Deployment in Amazon Web Services</InternalLink>
* <InternalLink path="byoc-azure-deployment">Prepare a CockroachDB Cloud BYOC Deployment in Azure</InternalLink>
* <InternalLink path="byoc-gcp-deployment">Prepare a CockroachDB Cloud BYOC Deployment in Google Cloud Platform</InternalLink>

Once your cloud account is prepared for a BYOC deployment, cluster configuration and management is identical to a CockroachDB CockroachDB Cloud Advanced cluster. To learn more about CockroachDB CockroachDB Cloud Advanced cluster planning and management, refer to the following guides:
