Have you ever found yourself increasing the Argo CD controller CPU? Give it more memory? The answer is most likely yes, multiple times! But there comes a time when enough is enough. In this talk, we will go over as many scalability symptoms as possible, understand why they happen and how to mitigate them. You will learn that most of the time, increasing the resources is only a temporary fix. Our goal will be to dive deeper into each problem to find the underlying root cause, and apply a solution that addresses the problem at its source to have a lasting fix.
CPU consumption, reconciliation cycles, operation queues, cluster watches, monorepos and much more are on the agenda.
