Backstage collects all of those (and more) into a single UI. In a pre-orchestration world, installation scripts would often be used to start applications, but they did not allow recovery from machine failure. However, over the past few weeks it's come up in conversation with engineers whose opinions I respect, As the discussion on the Helm GitHub issue shows, Helm recommends a one-to-one relationship between application and Helm chart.
