Would you host apps in Kubernetes even if they don't make full use of it, just to use a consistent set of devops tools?

Hi all,

I'm on a team right now that is converting a lot of apps that are running on ec2 over to eks, and we're starting with apps that make the most sense for eks. Apps like LGTM stack which have lots of distributed components, Airflow, etc.

We're setting up flux and renovate which really streamlines maintenance, and I like it so much that I'm wondering about converting apps that aren't particularly well suited for kubernetes over to eks just to use the same toolset.

We have some apps on ec2 that are essentially just a single docker container, they can be run in parallel but they don't have to talk to each other.

Some of these apps don't require many resources, so the $70 / month control plane cost of EKS is significant, which I imagine is the biggest reason we wouldn't convert over.

Just curious what thoughts are on this.
