Frequently there is a need to cover more than one domain on your Acquia Cloud site(s) under SSL so that they're reachable via https://... URLs. This article details some limitations and tips on how to achieve that.

Acquia Cloud Professional Customers
-----------------------------------

Since Acquia Cloud Professional applications are limited to one SSL certificate per environment (dev/stage/prod), if you need multiple domains covered under SSL, you will need to upload a single SSL certificate to the environment. (See [https://docs.acquia.com/acquia-cloud/manage/ssl/cert/#cloud-install-ssl-cert](/node/56371)).  
  
One option is a **Wildcard Certificate** which covers any domain that matches a root domain.

*   One option is a **Wildcard Certificate** which covers any domain that matches a root domain.
    *   For example, a Wildcard cert for **\*.domain.com** would secure **example1.domain.com**, **example2.domain.com**, etc.
    *   For more info see [http://www.networksolutions.com/SSL-certificates/wildcard-certificate.jsp](http://www.networksolutions.com/SSL-certificates/wildcard-certificate.jsp)
*   Another option is a **Unified Communications Certificate (UCC)**, which covers multiple domains.
    *   A UCC Certificate is also known as "Multi-Domain Certificate" or "SAN Certificate".

Please consult your SSL vendor to determine what options are available to you.

Note that you can use the same certificate for different applications/environments. This means that if you already own a single certificate that protects all your domains (including non-production), you can upload that certificate to each environment on each application via the Acquia Cloud UI.

Be aware, wild card domains will only cover a single sub-domain as seen in the example below,

*   This will work **\*.domain.com** (www.domain.com)
*   This will not work **\*.\*.domain.com** (www.qa.domain.com)

### Workarounds

If you want to avoid getting a Wildcard or UCC Certificate, there are some workarounds you can try:

*   For testing purposes, since Acquia Cloud lets you have a different certificate per environment, you could opt to test an existing certificate there (and then replace the original afterwards).
    *   It may be necessary to talk to your DNS provider to point DNS to a different IP.
*   If you were to route traffic through a CDN then that CDN offering may let you have an individual/different SSL certificate per each domain.
*   You could also use an additional application within your Acquia subscription, which can have a different SSL certificate than your original application.
*   If you have two SSL certificates that need to be used on one Prod environment, you could install one cert as a "Legacy/ELB" cert and the other as a non-Legacy/Standard SSL cert.
