In February 2023, Uber initiated a significant transition from traditional on-premise data centers to Oracle Cloud Infrastructure and Google Cloud Platform. Central to this shift was the integration of ARM-based computers into an existing x86 architecture, aimed at reducing operational costs and enhancing price performance amidst supply chain challenges. The architectural disparities between x86 and ARM presented Uber's infrastructure team with the necessity to fundamentally reassess systems that had been heavily reliant on x86, highlighting the far-reaching impact of architecture assumptions on their technology framework, with ARM's energy efficiency offering a compelling advantage in modern data centers.
"Uber has embarked on a strategic migration from on-premise data centers to Oracle Cloud Infrastructure and Google Cloud Platform, integrating ARM-based computers for cost reduction and hardware flexibility."
"The architectural differences between x86 and ARM processors require a fundamental rethink of systems, as Uber's infrastructure team discovered, revealing deep assumptions embedded in technology stacks."
