Bezeq is an Israeli leading telecommunication company offering a range of telecom services, including fixed-line, mobile telephony, high-speed Internet, transmission, and pay TV.

The company counted on maintaining a leading position in the market by modernizing its IT infrastructure and migrating the core business system - managing over 16 Mio of transactions per day - from a z/OS mainframe and IDMS database to a Linux environment and a relational Oracle database.

The Challenges

Migrating the business applications was the solution to address a series of business challenges and needs:

  • Integration of information systems
  • Reducing the infrastructure maintenance costs
  • Launch new services in shorter periods of time and with reduced investment in development and maintenance

The Project

Astadia was chosen to migrate over 100,000 complex ADS and COBOL programs, representing close to 10 Million lines of code. The automated modernization approach and proprietary testing tools allowed the project team to complete this entire migration project in only 20 months.

“We were able to exceed timing goals and stay within the budget. While our modernization solutions and unique methodology played a crucial role in the outcome of this project, we could only succeed with the trust from the Bezeq management team and the commitment of the experienced technical teams from Bezeq and Astadia.” - Louis Heymans, Managing Director, Astadia
“It truly felt like the Astadia team was an integrated part of our team and we clearly shared the same goals. By migrating to open systems, we eliminated an important cost and took an important step in our IT optimization process, allowing us to grow and adapt even quicker to future business changes.” - Eli Frank, Vice President of IT at Bezeq


Some of the benefits that the migration project brought to Bezeq include:

  • Complete elimination of the mainframe platform
  • A modern development environment
  • Bezeq achieved a 95% maintenance cost reduction, which resulted in a project ROI of less than 2 years
