Running an Ethereum Validator node on a cloud server is not feasible. We can host your node server, run and maintain it in our data center 24x7. You have access only to your server.

We will provide Ethereum and Flux NaaS facility in the future.
We may also provide NaaS facility for Cardano as well.
Some other nodes may be added later.

You can use PSP tokens to pay for the service at a discounted rate.
