@Dinesh S Could you confirm in which region are you trying to install Azure FarmBeats? Below are the supported regions.
You have mentioned, "one deployment always fails to get completed" did you install multiple times?
If you are restarting the install because of an error, ensure to delete the Resource Group or delete all resources from the Resource Group before re-triggering the installation
Also, I would suggest you, please go through the documentation for Troubleshoot Azure FarmBeats installation issues.
Let us know if that helps.
