Rehost and Replatform Valuable Legacy Assets

Solution Overview

Enterprise IBM^® CICS^® transactions, IBM^® IMS^® applications, as well as IDMS, Adabas Natural, IDEAL Datacom, and related workloads typically contain valuable, time-proven business models and logic, often unique to a particular company. Mainframe rehosting and replatforming solutions from Clerity can preserve critical program code on open UNIX, Linux, and Linux on System z servers while reducing costs as much as 70% .

The Challenge

You may be satisfied with the functionality your current applications provide, but your organization could benefit from operating your workloads on a lower cost platform or offloading a portion of your processing requirements to cap MIPS growth. Your legacy environment may have a similar profile to the following and you are unsure of how this workload could be addressed on open systems: IBM^® z/OS^® or IBM^® z/VSE^® operating systems, COBOL or PL/1 programming language, SNA communication services, VSAM file access, 3270 'green screen' user presentation, and IBM CICS application server or IBM IMS middleware supporting the transactional development model linking technology infrastructure to the business assets of business rules, data, and people.

How can you evolve to beneficial technologies such as Java and SOA without wasting resources or eliminating critical and unique business functions?

The Solution

Mainframe rehosting and replatforming solutions from Clerity preserve business logic and protect existing investments in legacy applications. Clerity can help improve the competitiveness of your business by integrating legacy applications with new applications and maintaining the end user's experience while yielding cost savings of as much as 70%.

Preserve Application and Data Investments

Clerity's mainframe rehosting software and related services provide the ability to move custom, home-grown applications to open systems platforms such as UNIX^®, Linux^®, and Linux on the mainframe. Existing applications, VSAM files, and data sources are migrated largely unchanged with the help of UniKix Transaction Processing Environment (TPE) software and UniKix Batch Processing Environment (BPE) software.

Redeploy Your Complete Environment Without Disruption

Legacy application environments typically utilize a wide-range of infrastructure tools and utilities. The Clerity Mainframe Rehosting Reference Architecture delivers the standards IT-orientated businesses have come to expect - standards which include enabling flexible functionality, high availability, scalable performance and extensibility - on open systems platforms.
