Terraform examples to launch Talos.

I store here the terraform code to launch Talos in the clouds. I wouldn't use the terrafrom modules from internet. The goal is to create all cloud services from scratch.

Ideas

First, I will create separate clusters on each cloud provider, test them thoroughly, and bring them close to production readiness. When I merge these separate Kubernetes clusters into one, they will have a single control plane.

Why is it so important?

Having a single Kubernetes control plane that spans multiple cloud providers can offer several benefits:

Improved resilience and availability: By using multiple cloud providers, you can reduce the risk of downtime due to a single point of failure.
Flexibility: A single control plane allows you to easily move workloads between different cloud providers, depending on your needs.
Cost savings: You can take advantage of the different pricing models and discounts offered by different cloud providers to save on costs.
Improved security: By using multiple cloud providers, you can implement a defense-in-depth strategy to protect your data and reduce the risk of a security breach.

Multi cloud compatibility

CCM compatibility, which can work together:

Talos CCM in mode: cloud-node
Other CCMs in mode: cloud-node-lifecycle
