CKAN Galvanize is a Platform as a Service (PaaS) approach for providing a hosted CKAN service for those who are interested in establishing or maintaining an open data platform.
The approach used is to establish a standard infrastructure architecture on Amazon Web Services which allows for automated deployment and ongoing management to reduce management costs.
The environments established for our customers are not shared. In fact, each environment is established within its own AWS account to allow for segregation and security. This also allows for cost management options where a client may wish to consolidate their AWS billing under a central account outside of of our control and directly pay for their own AWS fees.
