The cautionary tale of Heritage Retail
Imagine a company that for many years has been a household name in retail. Despite its longstanding success, more recently ‘Heritage Retail’ had a problem. It was rapidly losing market share to cloud-native online retailers with lower costs, greater agility and better customer insights. With revenue shrinking, their executives knew they had to act.
The vision was to transition from a monolithic, on-premises infrastructure to a nimble, cloud-native ecosystem to enhance customer experience and leverage advanced analytics. The initial stages of the project seemed promising, however, as the project moved towards their core operations, the crippling effects of data gravity and data inertia became painfully apparent.
Their decades-old, on-premises CRM and sales data warehouse contained petabytes of data. Because this database was an operational fulcrum, business critical apps like the company's e-commerce platform and supply chain management system were built around it. Years of ad-hoc integrations and data feeds had created a complex and poorly documented web of dependencies.
In data gravity terms, the mass of the data meant that moving one piece of the puzzle was impossible without moving all the interconnected pieces simultaneously. The sheer volume of data meant that the egress fees for migration would be eye-watering.
The team was faced with a stark choice: either embark on a ‘big bang’ migration of the entire, tangled ecosystem – an expensive and risky undertaking – or keep the applications on-premises, effectively halting the modernisation of this critical business function.
For Heritage Retail, failure to iteratively modernise towards a long-term vision meant they had painted themselves into a corner. Data gravity, rather than strategic planning, had been the driving force behind their IT evolution. Compounding over time, its effects had created a mass of interdependent systems and data too cumbersome to feasibly modernise. By the time they needed to respond, their most valuable data assets were locked in a state of inertia, thwarting their goal of adapting and competing in the new market paradigm.
