callas software presents solution for auto-scalable & pay-per-use environments

15 Mar 2019


Berlin, March 15, 2019 – callas software, a leading provider of automated PDF quality assurance and archiving solutions, presents the callas License Server, a product that addresses the needs of a modern, cloud-based world. Conceived with cloud infrastructure in mind, it introduces a more dynamic way of licensing processing capacity based on peak performance.

The callas License Server fits in callas’ long-standing tradition to provide a maximum of flexibility when it comes to the use and deployment of its products and technology. As such, callas products have been available for many years on Windows, Mac, Linux, Sun Solaris and AIX and its technology can be embedded through hot folders, command-line interface and a software development kit. With the callas License Server, the company adapts that philosophy to the current needs of the market and enabling a straightforward deployment of callas products and technology on infrastructure as a service environment like Amazon Web Services, Microsoft Azure or others.

Activation-based licensing vs. License Server-based licensing

All customers currently use activation-based licensing, which binds the license to the machine it is running on. From now on, License Server-based licensing will also allow callas software products to run without being activated locally, rather checking with the License Server whether any licenses are available. This allows (virtual) machines to be brought online without having to go through the manual activation process.

Full flexibility: auto-scalable & pay-per-use environments

The callas License Server makes models such as ‘load on demand’ or ‘capacity on demand’ possible, a more dynamic way of licensing based on peak performance.

How does it work? You either buy process cartridges and/or credit cartridges that are loaded in the callas License Server. One Process Cartridge enables you to run one callas process, processing one file at a time. Consequently, eight Process Cartridges will enable you to run 8 processes in parallel, no matter whether this is on one or more (virtual) machines. Process Cartridges would typically be used to run the daily production. To cater for peak production, the Credit Cartridges provide access to processing time, regardless of the number of parallel processes and/or (virtual) machines. For instance, a 50 000 Credit Cartridge handles 50 000 seconds of processing time. In an auto-scalable environment, this would allow for an unlimited number of server instances to be fired up, processing files until all credits are used, providing customers access to unprecedented PDF processing power. For pure pay-per-use cases, customers could of course choose to just use Credit Cartridges.
