The Clerity MFRRA brings mainframe rehosting to life by showcasing a real-world implementation of Mainframe Rehosting at Transamerica Life Canada (TLC). This version of the reference architecture, which is based on TLC's Capsil system life insurance solution, provides a fully tested, tuned, and documented implementation of a rehosted mainframe workload running on an AIX, HP-UX or Solaris platform. A Linux specific version of the MFRRA will be available in the near future.

The Clerity MFRRA is built upon several key criteria that Clerity considers essential to the design, deployment and maintenance of any successful IT implementation. Today's enterprise solutions must address the standards IT-orientated businesses have come to expect - standards which include enabling flexible functionality, high availability, scalable performance and extensibility.

Mainframe application environments typically utilize a wide-range of infrastructure tools and utilities. Therefore, the Clerity MFRRA places considerable emphasis on demonstrating how these third party tools and utilities can be deployed in a Clerity Mainframe Rehosting environment.
