Kubernetes is a complex framework for a complex job. Managing several containers can be complicated, and managing hundreds and thousands of them is essentially just not humanly possible. Kubernetes makes highly available and highly scaled cloud applications a reality, and it usually does its job remarkably well. However, people don[he]#039[/he]t tend to notice the days and months of success. Months and years of smooth operation aren[he]#039[/he]t the things that result in phone calls at 2 AM. In IT, it[he]#039[/he]s the failures that count. And unfortunately, failures don[he]#039[/he]t run on a schedule.
