I realize there is no option from the UI to install a customized app (it is not listed in Splunk app store) .
I was wondering whether anybody was able to install their own app in Splunk Cloud.
Also, is it possible to open a Splunk support tickets, and provide the app to Support where they can untar my app into ../etc/app in my cloud instance?
For custom apps, you need to open support ticket to have them install and perform any server side configurations. You should have all the required contacts in your contract and support documentation to do this.

The above answer is out of date. Today, the Splunk Cloud Platform supports self-service installation of both public apps on Splunkbase and private apps that you create for your deployment.
