Cloudflare’s mission is to help build a better Internet. Today, the Internet is the lifeblood of business and the primary vehicle of commerce and communication for people around the world. While it was brilliantly architected to deliver fault tolerance and robust connectivity, it was not designed to deliver the security, millisecond performance, and reliability required for businesses today. For decades, a number of vendors have looked to address the core limitations and vulnerabilities of the Internet for businesses that operate online. These vendors built a range of standalone hardware boxes to address the emerging requirements for security, performance, and reliability. These boxes could be deployed in on-premise data centers to deliver functions such as virtual private network (VPN), firewall, routing, traffic optimization, load balancing, and other network services. While they created massive complexity, cost, technical debt, and a tangled web of dependencies for the organizations that deployed them, the approach generally worked and these on-premise “band-aid boxes” were able to alleviate some of the Internet’s fundamental security, performance, and reliability problems.
