I am posting on behalf of one of our Cloud Beta users:
I’m working on processes that will be able to import data from and export data to the cloud. These processes will run on SQL Server and will be executed as jobs on a regular schedule by the SQL Server Agent. I watched the prerequisite videos, then spent several days reviewing forums and reading documentation for some of you other, similar products. I was able to get linked servers to my both my Sandbox and live instances functioning and will soon be working on some tests with your bulk load option.
Note: Assuming security is set up properly on the SQL Server, credentials will be passed properly to the DataDirect Cloud even when code is executed autononmously by the SQL Server Agent. It's easiest to quickly verify the linked server is functioning by running a simple OpenQuery via Query Analyzer.
