RADL (Resource and Application Description Language)

RADL is an early attempt at a resource description language, developed before related open standards such as OCCI (Open Cloud Computing Interface) were introduced. It is used in the GRyCAP Infarstructure Manager.

From the GryCAP Web site: The main purpose of the Resource and Application description Language (RADL) is to specify the requirements of the scientific applications needed to be deployed in a virtualized computational infrastructure (cloud). Using a declarative scheme RADL considers distinct features related to

  • hardware, like CPU number, CPU architecture, and RAM size;
  • software, like applications, libraries and data base systems;
  • network, like network interface and DNS configuration; and
  • contextualization, extra steps to set up an adequate environment for the application.

RADL is intended to be more abstract that other standards to specify virtual appliances, like OVF, and easily extensible with other tools, like contextualization languages such as Ansible.
