A Tableau Server can run happily for years, until an SSL certificate expires or an OS patch lands and support tells you the version is no longer supported. Brad Fair uses a pegboard picture to show how every piece of your analytics stack moves at its own pace, and why the gap grows the longer you wait. He breaks updates down by scope and size, explains what deferred maintenance really costs and compares monthly, quarterly and longer update cycles. Useful reading for any server admin, or anyone making the case for regular upgrades.
