That's easy:

1. Register on Open Exchange - in your case just sign in with same credentials as on DC.

2. In your personal page submit a new app which is the set of Name, Description, Github, License and Product link.

3. Submit for Approval.

That's it.

Once approved start to receive the traffic for your application via Open Exchange.

There is a dedicated post on how to submit the application

Thanks, Robert!

I realized now that DR site should be in another cloud and on a distance because of the purpose.

DR is being implemented as ASYNC Mirror in InterSystems and I think the network performance/bandwidth is the key.

All you mentioned here is fair enough, thanks.

And what I realize in the end that network bandwidth requirements totally depends on the transactions load of the PRIMARY.

The hardware requirements of DR site is an easier thing - DR site can have the same configuration as PRIMARY.

Hi Felipe!

Are you able to edit ANY files with VSCode? With ObjectScript files, it should be the same.

Just to make sure: 

1. - check out your ObjectScript files from the repository to a local file folder.

2. Open this folder in VSCode.

3. Setup the connection in VSCode to an InterSystems server and namespace you want your files to be compiled.

4. Code it!

There are also other steps of commit/push/test/patch/deploy - but it is another story.
