One of my production web-based projects managing critical transit data hit the 12 year mark. It was based on straight HTML/CSS, plain Javascript, Knockout.js (yeah, this was before ReactJS and friends), JQuery, Bootstrap CSS, and with a Play Java backend on Centos Linux against a Oracle 11 DB. It needed minimal maintenance and updates, only when the spec versions changed. It has reached its end of rope when it failed the new security audit in that the software versions being too old, i.e. Oracle, Linux and JDK being too old. The customer comes up with the funding to do a rewrite rather than spending the money in retrofitting the old code. You bet one of the main goals of the new tech stack is reducing 3rd party dependencies and choosing dependencies carefully.
