Data Gateway vs Data Transfer

[Mapuna]

1. What is the difference b/w Qlik data gateway and Qlik data transfer tool?

2. Can both be installed on same server?

3. Any SSL or any certificates necessary to work along with these tools in terms of data security?

Data Transfer

• Qlik DataTransfer is a lightweight Windows application that lets you upload data from on-premises data sources to a Qlik Cloud tenant without firewall tunneling.

• Qlik DataTransfer works with the following kinds of data sources:
  • App data
  • Connection data
  • Folders
• Reloads an App locally and uploads the tables as QVD to a Space
• It can also monitor a folder that can be synced/uploaded to a Space.
• After an upload you can trigger an app to reload.
• Data Transfer is getting old, last update is Nov 2, 2022. 

Data Gateway

• Creates a "tunnel" between your server and your Qlik tenant. All reloads take place in Cloud, you have to use the Direct Connection connectors. The ODBC connector can be used where there is no embedded version directly available, install and create an 64bit ODBC connection on the local server.
• Create a new connection and search for direct access

2 installed on same server

Yes they can be installed on the same machine

3 SSL

No thirdparty certificates are needed.

Data Transfer uses an API token, DataGateway creates a key

Thanks for replying.

But for question number 2, contrary to your answer, this is what i read from community: 

"Direct Access gateway should be installed on a dedicated Windows Server.Do not install it on the actual database server
or alongside other Qlik products,including but not limited to, Qlik DataTransfer, Qlik Sense Desktop,
and Qlik Sense Enterprise."

any thoughts?

Hi @Mapuna ,

while it is possible to run the two products on the same machine, there might performance issues due to conflicts, and it's therefore not a supported scenario.

Some might run them on the same machine for testing purposes, but they should not be used together for any actual production or active development purpose.

Please, also note that QDT will eventually be fased out, with full feature parity in the Direct Access gateway.

Indeed, from my experience installing them both on the same server does not work properly. I believe folder-support is being released soon for the Data Gateway, therefore the Gateway is preferred above the Transfer Tool from then on.
