When looking at the Charon-SSP product features, one can look at the differences between the different emulated models (as shown in Virtual Hardware and Guest OS Supported by Charon-SSP AWS).
Another comparison is the comparison between the different product variants. This section provides an overview of important differences between the product variants.
...
The basic functionality of Charon-SSP in the different product variants is very similar. However, the product variants also have important differences.
Currently available Charon-SSP product variants:
Conventional product
Individual RPM installation
Barebone installation
Baremetal version
Amazon AWS version
...
This product variant exists in two flavors:
Product The product is installed as individual RPM packages on a supported Linux distribution and version.
Product The product is delivered as an ISO installation file that contains the operating system, the product RPMs and any additional software typically required (Barebone version).
The conventional product, especially when installed as individual RPM packages, offers the greatest flexibility for any customizations customization and for integration into the customers’ system management environments.
...
The instance configuration (e.g., network configuration) can be adapted to the customer’s requirement, but only a subset of a full Linux host operating system is accessible.
