The link failed to medium for me. Would you mind describing in a little more detail some things? What DB are you using? How mature are your automation tools for managing these DB instances? Do you use a “single” DB server instance with a database defined per customer? Do you require all your customers to have identical schema, and do upgrade them all irrespective of individual customer concerns? Thanks in advance!
