We currently use Retool's self-hosted solution and are considering migrating to the Cloud Business Solution.
We have two key questions:
What are the steps for migrating from our self-hosted setup to the Cloud Business Solution?
How can we securely connect Retool Cloud to our internal services, which are behind a VPN?
how does the design of using a retool cloud solution and connecting him to the internal services look like? maybe using a bastion in the middle?
We actually have a fairly thorough guide to walk you through the process. It's a pretty painless process if you're using source control and honestly not too difficult even if you aren't.
As to your second question, your intuition is exactly right. You would set up a bastion and configure all of your cloud resources to use an SSH tunnel when connecting to your internal services.
Don't hesitate to follow up here if you have any questions!
