This has been such a game-changer for me.
Our new custom-developed back-end hooks into all our resources and provides a holistic view of our infrastructure in a single pane of glass. We can dig into each service and application for troubleshooting and analysis, but the biggest feature is that it pushes a notification when new updates are available.
This way, I'm not logging into each asset individually; I just say "yup, looks good, update," and it does it.
Years saved off my life.
I'll share more about this tool during our upcoming Spring State of the Instance, of which the date will be announced this upcoming week.
And yes, I will be offering the repo for others to fork and use when I'm comfortable doing so. It's very custom-tailored to our infrastructure, but I'm sure many aspects can be reused.
