I have been working on role based access control in cloud for which I have coded some java programs. I would like to upload and run those java programs on a real-time cloud. I have no idea about uploading a "file" onto the cloud although i have a decent knowledge on uploading the boot images on them. Is there any way to run my programs on a real-time cloud like cloudstack,openstack,eucalyptus etc.? I am currently working on ubuntu cloud(maas).
