I have a lot of experience in Kubernetes. The backend of this website is running on a Kubernetes cluster hosted by me.
Almost all of the deployments I've done use Helm for templating and composition of components.
This is my preferred Cloud Provider. Everything I do for personal stuff is hosted on Hetzner.
I can only recommend them for personal as well as professional use.
Everybody knows this one. I have worked with AWS but it isn't really my favorite thign to work with.
I love Terraform. Makes working with AWS really nice and spinning up Kubernetes clusters on Hetzner is a charm with it.
Ansible is awesome for stuff you don't really want to do with Terraform. I do have quite a bit experience using Ansible.
