Edge Computing and Edge Caching

Moving computation and content closer to users — turning 150ms round trips into 15ms responses by running code at the network edge.


Key Takeaways

  1. Edge computing moves computation closer to users — reducing latency from 150ms (origin) to 15ms (edge PoP)
  2. Edge caching stores content at CDN PoPs worldwide — cache hits are served in milliseconds without reaching the origin
  3. Edge functions run serverless code at the edge — A/B testing, authentication, and personalization with near-zero added latency
  4. Edge is ideal for read-heavy, latency-sensitive workloads — static content, API responses, and computed personalizations
