Kubernetes - Monitoring and Alerting

With Kubernetes, you can have two different environments that serve as your production environment. So maybe blue is currently online and then you upgrade green and then you swap over to it. You didn't change the code on that other piece of infrastructure yet because you still need to diagnose what the problem is. Have some monitoring and alerting set up so that when things do go wrong, you get a notification. Having good training around how to use software in cases like that is really important.
