Deployment from one environment to another environment

Hi All,

I would like to know the best approach of deploying the power bi dashboard, not sure whether you can help me here. Here is my scenario:

1. We are a consulting company and we develop the power bi reports internally on our organization premise with o365 by replicating our clients environment internally
2. The end users of the power bi dashboard is another external organization with their own domain, may not have 0365
3. How am I supposed to do the deployment of dashboard seamlessly into their domain pointing to the database in the external organizations network?
4. I don’t have a login under the external organizations domain, I use my organizations domain name 

I am finding it very challenging to do using power BI when it comes to deploying to the organizations domain. Can somebody help me the best approach on this ?

It would be great if you can point me to the right contact or any documentation on this.

Cheers,

Anoop
