From Mainframe to Cloud in Realtime

tcVISION in the Cloud – The right data in the right time – in the cloud, too.

The Challenge

In the digital age Big Data and Analytics are widely being talked about. The efficient integration of mainframe data has multiple reasons: Big Data, Workload relief of the mainframe to reduce cost, application modernization together with data- and application-migrations without a „Big Bang“. Declining mainframe knowhow, databases and their complexities grown over decades. All of these facts are big challenges when it come to data exchange in a mainframe environment.

Many corporations used FTP or other file-transfer solutions to resolve the data exchange problem realizing that this was extremely CPU intensive, insecure and created high costs for the distribution of mass data. Today these solutions are not acceptable nor practicable any more. Not only because of costs but also because of limited batch windows.

The solution

There is a better solution to manage and master this complex and ambitious task in an easy, fast, reliable and efficient way: tcVISION for the timely, bi-directional data synchronization and replication based upon changed data. With tcVISION the data exchange becomes a single-step operation. No middleware or message queueing is required. The data is exchanged in raw format, compressed and reduced to the processing of changed data.


  • Because the focus is on changed data (Changed Data Capture) the data transfer volume is reduced to a minimum
  • Highest topicality through continuous real-time processing
  • Cost reduction through relocation of data exchange processes from the mainframe to cost efficient platforms (e.g. MS Azure, amazon cloud, others)
  • Cost reduction through compressed data transfers
  • High integration potential of the tcVISION solution: multiple Change Data Capture technologies can be used depending upon change frequencies and latency times
  • Comfortable data mapping
  • Prevention of mainframe costs: integrated data repository creates transparency for all available data
  • No additional middleware required – Elimination of costs and implementation efforts – efficient transport-layer
  • Elimination of programming efforts for data transfers
  • Comprehensive conversion of historically developed data structures
  • Integrated Pooling/Streaming processes avoid programming efforts and message queueing to prevent data loss because of unavailability of the target system or delays
  • Processes which have proven to work in practice are available to restart a replication after system failures (database errors, transmission errors etc.)

Application examples

  • Synchronization of data in a heterogenous system environment consisting of a mainframe and mobile applications which make use of data from cloud solutions
  • Gradual migration of data and applications in in cloud-based solutions
  • Transfer of database data to various databases hosted by the cloud solution
  • Provision of mainframe data in cloud systems for Data Warehousing, ETL, Business Intelligence, Analytics & Big Data


Intuitive mapping offers comprehensive possibilities for data modeling and a variety of integrated functions for the transformation of data types between meinframes and databases in – as a sample here: MS Azure – including packed fields on the mainframe. The complete change of the data model is self-evident – even in a bi-directional replication.
