It’s 4:00 in the morning, and you are awoken out of a sound sleep by a phone call from your cloud-ops center. It looks like- the repository app in the public cloud is down.
You know this because of a particular tile on a particular application monitoring console turned from green to red. Those charged with monitoring public cloud-based applications only know that if this particular application goes down, they need to call the app admin and that is you.
Through blurry eyes, you find that a middleware process died on one of your cloud machine’s instances. A quick reset of that instance and you’re back in business and back to sleep—at least for 30 minutes before your alarm goes off.
