 ## Summary
 
-To summarize, the Cloudflare CDN is SaaS that helps address the challenges customers face around latency, performance, availability, redundancy, security, and costs. The Cloudflare CDN leverages Cloudflare’s global anycast network and Tiered Cache to deliver optimized results while saving costs for customers. Customers can also enable Argo Smart Routing to ensure the fastest network path is used to route requests to the origin server and also choose to enable Cache Reserve to increase cache hits to further save costs and increase performance of their website or application.
