Cloudflare – What is it and why would I care ?
I have been using Cloudflare for a long time. It is one of my goto services and I use it to protect all of the public services I run for myself and other sites/ organizations.
The basic premise of what Cloudflare do is that they are a distributed Web Application Firewall (WAF) and CDN but they also offer so much more. Because they have a large number of POP’s they can cache and push content closer to your end users to give them a better experience. This also offloads work from your firewall’s, DNS, Web and Database servers. At present they have 139 sites globally allowing you to host a site anywhere and get good global performance.
Cloudflare has an amazing free tier so you can get started easily. I use this to host all of my public DNS records. So what does that look like?
