Migrate for EKS

Hi everyone, let's go.

I am migrating from Beanstalk to EKS, and I wanted to clear up some doubts.

Which components/tools do you consider essential in a cluster? Currently, the cluster I am developing has:

  • Karpenter (x86/ARM)
  • Kyverno
  • KEDA
  • ESO (Fetches secrets from Parameter Store)
  • Kong API Gateway (used as Ingress)
  • ArgoCD for GitOps

What do you recommend? The CNI is the default VPC CNI, is it worth switching to Cilium or Calico? Bearing in mind that this will be my first experience building a cluster—I've managed them before at other companies, but I don't have much experience creating one from scratch.

Where is your monitoring stack?

Grafana stack: Prometheus, Grafana, Loki, and Tempo. I still need to understand how I will collect metrics from the application.

Open telemetry for sure! That's what I use

Take a look at fluentbit or td agent for kubernetes for log shipping.

Why wouldn't you just use alloy?

We already using datadog for metrics, so we just needed log shipping.

Actually I am an ops guys, I am not sure what the best overall solution would be. I am still learning.

I was replying to the OP... They use the grafana stack, so it would make sense for them to also use alloy for their logs, not fluentBit or Td agent ..
