            Availability:
                Schemas and data are online. Each schema has one or two examples modelling Services from Amazon. One exception is textbf{ccdm} which has 6 examples of different ML experiments.
            &
            textbf{ccpricing} can not handle the complexity of most common price options, like cost of OS to be installed on the VM, network data transfer cost differed by destination and usage, snapshot storage costs and etc. textbf{ccinstances} does not allow unit to be specified in data, has to be fixed for each property.
