Systems Deep Dive: Concurrency & Edge Compute

Question

Discuss concurrency and edge-compute internals: how you'd run untrusted code safely at the edge (Workers/isolates), and how you avoid race conditions in a high-throughput proxy.

What this round covers

• Isolates vs containers vs processes for multi-tenant edge code
• Concurrency primitives and avoiding shared-state races
• DNS resolution and DDoS mitigation at scale
• Memory/latency budgets at the edge

Tips

Cloudflare lives close to the network stack. Show you can reason about concurrency, isolation, and tail latency.
