We have fully reimplemented our consumer identity stack, enabling customers to purchase content and service products and use web and mobile-based navigation services. The previous “leader-quadrant” solution had high software license costs and was difficult to operate – we replaced it with an open-source “niche player”. The main complexity was providing user provisioning and single sign-on for 10 web, mobile and embedded channels with minimal client change. The biggest challenge was near-zero down-time during cut-over, whilst preserving token state for millions of navigation devices. The new landscape offers feature parity while being vastly simpler and more affordable.
