As already suggested you could check if the product you need is provided as a Cloud service. However generally speaking on Virtual Servers (Virtual Machines) on Bluemix you can use a custom image (running RHEL or SUSE). As reported on Bluemix Virtual Servers docs:
A virtual server image is a file that includes a virtual disk with an
operating system installed on it.
You use a virtual server image to create a virtual server. You can use
an image that is provided by IBM, a customized virtual server image,
or a snapshot that you took of another virtual server.
Important: In Bluemix, you can upload virtual server images that are
supported by OpenStack and have qcow2 format only.
For more information, see Virtual server images - Private virtual server images.
