Why Every (great) System Design Uses Queues
Queues are one of the most underrated concepts in system design. They quietly power almost every scalable app you use.
From buffering traffic spikes, to enabling async APIs, to handling retries and DLQs, queues make modern systems reliable, resilient, and fast.
In this video, we’ll break down how queues actually work, where they fit into architecture diagrams, and why every big tech company (Amazon, Netflix, Stripe, etc.) relies on them.
