BT Group’s Digital Unit is working with Kyndryl to migrate mainframe applications which service its legacy copper business and consumer broadband products to the cloud.
The ten-year partnership, which draws on Kyndryl’s hyperscaler capabilities and partner ecosystem, will allow BT Group to reduce mainframe operating costs and energy consumption by 70%, leading to savings worth more than £17m a year by 2026.
“We like thinking out of the box to solve complex problems – like how to move off mainframes given the prohibitive increase in legacy infrastructure cost – without rewriting decades-old applications,” explains Harmeen Mehta, Chief Digital and Innovation Officer at BT Group. “With that mindset, working with Kyndryl, we figured out how to turn legacy mainframes into modern digital apps and run them at a fraction of the cost.”
Kyndryl, which currently runs BT Group’s mainframe estate, extends its partnership with BT to deliver the transformation project by 2026, accelerating the drive to reduce cost and open up data insights within these key applications. As part of the project, some applications are being “retired” (contributing to the Group’s target to get to fewer than 500 strategic systems by 2027, simplifying its technology estate), “refactored” (redeveloped into BT Group’s existing strategic systems and architecture) or rehosted (repackaged to operate in a cloud environment).
“It’s exciting to be partnering with BT Group on such an ambitious and critical programme. Migrating from mainframes to cloud extends the usefulness and lifespan of these applications in a modern, micro-services led, cloud-centric way and helps unlock intelligent data insights. We’re excited to draw on our deep knowledge, ecosystem of partners and community of industry leading experts to help deliver this transformation,” comments Petra Goude, Global Practice Leader, Core Enterprise & zCloud, Kyndryl.
