Businesses face constant pressure to reduce costs while at the same time improve efficiency and deliver more innovative products. Many organizations that use IBM mainframes have chosen to move production application workload that does not necessarily have to run on the mainframe onto alternative platforms. This is usually part of a strategy to contain, manage or reduce costs while increasing overall processing capacity. Taking this modernization approach has helped organizations reduce annual operating costs by up to 90%.
The key to successful rehosting projects is minimizing change to avoid unnecessary risk, while moving to an agile environment that can support future growth. The benefits are compelling but are unlikely to be realized unless the technology used to run the rehosted applications can: Deliver the performance and transaction throughput required by the business Meet Reliability, Availability and Serviceability (RAS) expectations Offer appropriate RACF compatible application and system level security Enable IT to proactively manage the health of the systems in production Access mainframe transactions and data that must remain on the mainframe Provide a flexible architecture that enables IT to respond rapidly to new business demands


Micro Focus Enterprise Server provides a high performance, scalable, deployment environment for hosting applications that have traditionally run on IBM z/OS, MVS or VSE environments. It also provides the infrastructure to support the integration of these applications with technologies such as .NET, J2EE, or SOA to better satisfy evolving business requirements.

Enterprise Server is built around a batch execution and transaction environment that supports IBM COBOL, IBM PL/I1, IBM JCL job streams, common batch utilities including SORT, IBM CICS and IMS TM transactions, and Web services. It also includes support for IBM DB2, IMS-DB and mainframe file formats.
The result is a single integrated deployment environment which provides the batch and transaction processing environment to execute mainframe applications on Linux (x86-32/64-bit or System z), UNIX and Windows servers2. This enables core online and batch application logic that has evolved over decades to define unique business processes and deliver competitive advantage, to be reused with minimum modification, on any of these cost effective environments.
While Enterprise Server supports the deployment of the migrated application, its companion product Micro Focus Enterprise Developer supports the development lifecycle and the continuous improvement of these applications now and into the future.


  • Exploit the price/performance ratio of powerful, competitively priced processors to cut annual operating costs by up to 90%
  • Redistribute suitable application workload to contain or gradually reduce MIPS on z/OS, in order to delay or avoid upgrades required to add processing capacity
  • Replicate applications on low cost platforms to satisfy regulatory requirements that dictate customer data must be kept within country
  • Duplicate discrete functions, like pricing quotes, to service new market requirements more effectively, for example, aggregator market quote fulfillment
  • Provide continuous service during scheduled mainframe downtime
  • Bring disaster recovery implementations in-house instead of using costly outsourcing services
  • Shrink batch cycle times by taking advantage of the processing power of modern processors
  • Deliver equivalent Quality of Service (QOS) levels at reduced cost
  • Provide better reporting, business intelligence and ad hoc reporting capabilities


  • Reduce risk – applications behave in the same way they did on the mainframe because the original code defining existing online and batch business processes is reused
  • Complete migration projects faster as applications can be migrated with minimum changes
  • Utilize mainframe compatible security models for authentication and authorization
  • Provide mainframe level Reliability, Availability and Serviceability (RAS) on open systems
  • Support modernization via new Web or graphical user interfaces that reuse traditional interfaces
  • Improve agility, as proven business functions can be exposed and executed as Web services for easier reuse within strategic architectures such as .NET, J2EE or SOA
  • Increase flexibility and future-proof business assets, as applications can be moved to popular Linux, UNIX or Windows environments to simplify business process integration demands
  • Explore the potential benefits of deploying traditional mainframe applications into new cloud environments
