We selected Cloudflare because they are widely recognized as the market leader in the CDN and reverse proxy space. Initially, we started using Cloudflare because of their extremely fast DNS resolvers, which are among the fastest available globally. Over time we expanded our usage and now rely on Cloudflare as the CDN and reverse proxy for all of our publicly exposed services. The platform provides a combination of CDN capabilities, integrated DDoS protection, and reverse proxy functionality that makes it very easy to securely expose services to the internet. Overall, Cloudflare offers a very mature platform that abstracts a lot of operational complexity and allows us to focus more on our applications rather than on infrastructure management.

Cloudflare generally performs well and offers good performance and security features. However, my main concern is reliability. Recently there have been several outages where Cloudflare went down, and when that happens it impacts a huge number of services at once.
