AWS, Azure, and Google Cloud built their businesses on massive, centralized data centers. Cloudflare took a different path. It started as a security and performance layer in front of other people's infrastructure, a CDN and firewall, and has grown into something closer to a full replacement for parts of the cloud stack.
For developers building high-concurrency applications, that shift matters. Here is the technical case for it.
1. R2 vs. S3: no egress fees
AWS, Azure, and GCP all charge egress fees: the cost of moving data out of their cloud. Store petabytes in S3 and moving it elsewhere gets expensive fast. That is the mechanism behind vendor lock-in.
Cloudflare R2 is an S3-compatible object store with zero egress fees. That removes the financial penalty for building multi-cloud architectures. Data is also stored and served closer to the user, which cuts the latency a regional data center adds by default.
2. Workers vs. Lambda: no cold starts
Traditional serverless functions like AWS Lambda run in containers or virtual machines, which means cold starts, a delay whenever a function has not run recently.
Cloudflare Workers run on V8 isolates, the same technology behind the Chrome browser. They spin up in milliseconds, which removes cold starts as a problem. A Worker also is not deployed to one region. It runs across Cloudflare's entire network at once, in data centers across more than 300 cities.
3. Hyperdrive and the database bottleneck
Edge computing has a data gravity problem. Your code runs at the edge, but your database sits in one central region.
Hyperdrive turns an existing regional database, Postgres for example, into a global one by managing connection pooling and caching at the edge. Connecting to a database on the other side of the planet ends up feeling local.
4. The 2025/2026 outage
Even Cloudflare goes down. In late 2025 or early 2026, a bug in its bot mitigation system caused a large outage. What stood out was the response: a detailed public post-mortem explaining exactly how a routine configuration change took down the network.
Publishing that level of detail instead of a vague statement is what earns trust from the engineers who depend on the platform every day.
Cloudflare has grown from a shield in front of a website into a programmable global network. Removing region selection and egress fees changes what engineers spend their time on: less infrastructure logistics, more building.
