The conversation with Valentino Volonghi, CTO of AdRoll, revolves around an intriguing application and infrastructure issue they encountered in the past. The company was experiencing a critical failure without any machine crashes or system malfunctions, which led to the adoption of Amazon's new C3 Instance Family for improved performance. However, after the upgrade, the machines weren't spending their budgets efficiently, causing a drop in revenue due to reduced processing power. An investigation revealed that long-lived connections were being held by specific instances, leading to an imbalance in machine utilization and budget allocation. To resolve this issue, AdRoll introduced random timeouts into the software to encourage rebalancing of connection allocation across different machines, effectively allocating resources efficiently even for long-lasting connections.
