Tableau online is a great solution for companies like ours, who have clients with a few users and who need to deploy solutions in multiple organizations--and who don't have the infrastructure to create their own server installation.Tableau Online enabled us to create the reports, push them out across the organization, and have different individuals in the organization connect to those reports online from any point in the world. It's extremely flexible. And from my perspective it's very cost-efficient.

It is used by businesses, academic researchers and many governments to do visual data analysis.
