Connectivity Cloud Provider
Cloudflare is a global connectivity cloud for CDN, DNS, security, Zero Trust, and Workers edge compute, not a general-purpose IaaS hyperscaler. It complements AWS, Azure, and GCP rather than replacing them for traditional cloud infrastructure.
CDN & DNS
Caching, performance, and fast authoritative DNS
Security
DDoS mitigation, WAF, bot management, rate limiting
Zero Trust
SASE access, secure web gateway, email security
Workers
Serverless edge compute, R2 storage, Workers AI
Complements the hyperscalers
Pairs with AWS, Azure, and GCP, not a replacement for general IaaS compute
Cloudflare sits between users and the apps, sites, and networks they connect to, adding performance, security, and reach. It runs on a single global edge rather than discrete regions, and works alongside the major cloud providers instead of replacing them.
A content delivery network and fast authoritative DNS cache and route traffic from a global edge. Cloudflare reports its network spans 330+ cities, designed to put content close to users.
DDoS mitigation, a web application firewall, bot management, and rate limiting protect what you put online. The SASE and Zero Trust suite covers access, a secure web gateway, and email security for teams retiring legacy VPNs.
Workers run serverless code on the edge, paired with R2 object storage and Workers AI. Cloudflare positions this as a complement to hyperscaler compute, not a like-for-like replacement for general-purpose IaaS.

Before You Rely On This Coverage
Plan prices, free-tier limits, and network scale (such as the 330+ edge cities figure) are reported by Cloudflare and can change. Always confirm current details on Cloudflare's own plans and pricing page before making a decision.
Cloudflare is a connectivity cloud for delivery, security, and edge compute. It is not a general-purpose IaaS hyperscaler and is best evaluated as a complement to providers like AWS, Azure, and Google Cloud, not a one-for-one replacement.
