Hi Guys, I want to switch to deploy starrocks to EC2 instead of EKS, wanted to know if this is possible or not?

what do you mean by "switch"? migrate from eks to ec2 instance? it is certainly possible to deploy a fresh new cluster on ec2 instance

what all cons are there if we deploy to ec2?

ec2 are vm based deployment, eks is based on k8s, it is different in managing and operating the cluster, there is no pros or cons of the solution, just how you are more comfortable/skilled to manage it.
