Mainframe Modernization: Extracting Business Value While Maintaining Critical Legacy Data

_0_Treehouse_tcV_Cloud_OpenSystems

Whether your enterprise wants to take advantage of the latest cloud services, such as analytics, artificial intelligence (AI), etc., or move your data to a variety of newer LUW or Open Systems databases, the transition doesn’t have to be a sudden big bang.

Application Rehost / Modernization Challenges

Much of an enterprise’s mission critical mainframe data is stored in legacy mainframe databases, and the cost to maintain these databases is high.  An added complication is that the data is utilized by many interlinked and dependent programs that have been in place for many years, and sometimes, decades. Unlocking the value of this legacy data is difficult due to many very different types of mainframe databases (e.g., Db2, Adabas, CA Datacom, CA IDMS, etc.).

Many customers are looking for a solution that allows their legacy environment to continue while replicating data in real time on a modern database/platform. This enables them to utilize modern programing and data tools in order to remain competitive in their markets.

One Step At A Time…

Treehouse Software has extensive experience in helping organizations incrementally replicate their mainframe data to the cloud and other modern systems, while keeping both sides synchronized.

Treehouse Software’s expert technical representatives help customers developed a phased plan that includes installation and implementation of the tcVISION mainframe data replication product. The plan then defines various parts of the solution, including:

  • configuration management
  • environments and promotion
  • high availability
  • security
  • disaster recovery
  • monitoring
  • operations procedures
  • script customization
  • data replication mapping
  • training

After defining the architecture, the production deployment phase begins with incremental sprint-like deployments. Additional files are then deployed into production every few weeks.

This phased plan enables the tcVISION product to synchronize mission critical mainframe data to any modern database. Bi-directional, real-time data synchronization allows changes on either platform to be reflected on the other platform (e.g., a change to a PostgreSQL table is reflected back on mainframe). The customer can then modernize their application on the cloud, open systems, etc. without disrupting the existing critical work on the legacy system.

Additionally, tcVISION customers see drastically reduced mainframe MIPS costs, and increased ability to quickly respond to business environment changes.
