Scality CTO Giorgio Regni opened by addressing the complex challenge of managing exabyte-scale distributed storage systems, which involve thousands of drives, intricate networking, and microservices architecture. He recounted Scality’s twelve-year journey in UI and UX design, starting with early customers like internet service providers who, coming from traditional SAN environments, demanded extensive control and visibility. This led to an initial design phase characterized by numerous manual controls and detailed dashboards, reflecting a desire to manage every aspect of the system, even when processes like data repair and balancing were automated.
However, this approach soon revealed its limitations. The proliferation of dashboards and alerts led to “dashboard fatigue,” where operators became overwhelmed by information and desensitized to notifications, missing critical issues until it was too late. Similarly, providing an excessive number of configuration variables, often requested by customers influenced by systems like Kubernetes, was deemed counterproductive. Regni highlighted that expecting customers to tune intricate distributed system parameters was impractical, as even engineers struggled with such granularity. This era solidified the realization that relying on humans as the primary control plane for such vast systems was inefficient and prone to error.
Scality’s new direction, embodied in their ADI design, aims to reinvent system management. It shifts from an imperative “tell the system to do things” model to a declarative one, where users specify desired outcomes, and the system autonomously delivers and monitors them. This modern UX leverages AI and expert agents to continuously observe the system’s state, act within defined guardrails, explain its actions, and escalate to human operators only when complex judgment or high risk is involved. The goal is a learning system that minimizes human login frequency, as happier customers are those who implicitly trust the system to manage itself effectively, allowing human intervention to be reserved for truly exceptional circumstances.
