Mainframe Migration: A Hybrid Approach to Manage Application Workloads

Abstract : Many fortune 500 banking organizations have started to migrate their mainframe application overloads towards open systems for enhancing flexibility in their core-banking applications, however only a few BFSI companies have completely migrated from mainframes. Large Fortune 500 banking companies have retained mainframes for managing critical applications and moved considerable workloads off the mainframes to achieve cost savings without compromising on efficiency and security. Migrating mainframes are not a cost-effective option for all enterprises. Migration effectiveness depends on the nature, business criticality of applications and the migrated system?s capability to handle MIPS workload of a mainframe. Though many enterprises have started to achieve cost savings through migration of mainframes, international banking corporations still install and renew mainframe contracts, thus making mainframe an inevitable part of the banking industry. Hence it is advisable for organizations to adopt a hybrid approach of maintaining workloads by which the applications having lesser criticality could be moved off mainframes to opens systems while maintaining critical workloads in the mainframes.
