We are a consulting group that works with about 300 healthcare clients. Our clients have asked us to create specific custom dashboards for them. We want to use Power BI as our tool. We would harnass the data and build the visualizations. The client would have their own login to just view the visualizations. What I need to know is what is the best way to accomplish this? Our clients are all over the United States. They are independent of one another so their data is confidential therfore separate databases. Due to HIPAA regulations their data cannot comingle. Some have asked for real time visualizations. We would typically connect to phone systems, Amazon EC2, other SQL databases. I was thinking something like having an Azure server running BI Desktop, but I don't know how many instances we can have (if we need them), computing power, cost, etc. What is the best way to accomplish a cloud based, real time power BI solution?
