is it possible to deploy two (2) SiteWise gateway configuration on single EC2 machine?

Question

I have a Prod and Dev AWS account, and I would like to bring in the live data within the DEV AWS account. The live data is connected to the PROD account via the following path (OPC-UA server -> Greengrass V2 SiteWise Gateway (running on an EC2) -> SiteWise Console). 
So the question: is it possible to create a new gateway in SiteWise ( in DEV account) and deploy it on the SAME server that's running the existing gateway for PROD?

Answer

Hi Roshan, it is possible to do what you want by installing a new Greengrass Core instance on the same server in a different root folder. From the Sitewise console, select **Create Gateway** and go through the Default Setup. Once the installation script has been dowloaded, open it and edit the line with

```
GREENGRASS_FOLDER="/greengrass"
```

replacing `"/greengrass"` with another folder.

If you are installing on Windows, just pass the new folder name as `-InstallPath` parameter to the script

NOTE:  This will not work if you are also installing the data processing pack, as this pack will open some ports that will conflict with those opened by the existing gateway.
