# Deploy a Certificate

After you upload your third-party certificate, you can deploy it to your Zenlayer cloud services.

## Prerequisites

1. You can deploy certificates to services like CDN or Global Accelerator. The service permissions vary by accounts. This illustration is for reference only.
2. The service that you want to deploy a certificate, must be configured with a domain name that is bound to this certificate.
3. If you want to enable the certificate-related functions such as HTTPS, you must deploy a certificate.
