Faced with a complex and unwieldy legacy estate, TalkTalk undertook an ambitious modernisation and transformation project, which streamlined their legacy estate to easier to manage, less complex, and more resilient systems.

Working in Collaboration with Capgemini, TalkTalk achieved a 50% reduction in its legacy code applications and databases within the first 18 months, and created a ‘can do’ culture that continues to dramatically improve.

TalkTalk achieved several tangible and intangible business benefits such as: 
- Improved the reliability of the app infrastructure stack
- New VMware server hardware and cache cards
- Re-platformed Salesforce
