Using Cloudflare to keep sites fast & secure
May 1, 2012
Cloudflare is a <a href="https://en.wikipedia.org/wiki/Content_delivery_network” title=[wiki] Content delivery network">CDN, site optimizer, and security product all rolled into one. The main feature that is of use to me (and most people, I presume) is the CDN portion which some have called a “poor man’s Akamai“. Cloudflare sits in front of your website and acts like a caching layer spread out across 14 global edge nodes. This means your site should be “fast” everywhere in the world, rather than just within 3,000 miles of your server. I’ve been using it for a few sites over the last couple of years and so far I’ve had good experiences with the service. It being free (with a premium option) has definitely helped.
Setting up PowerDNS Server with PowerDNS Recursor
September 10, 2010
I needed an open source DNS solution at work recently, preferably anything but Bind, and it was suggested I use PowerDNS. I had no experience with it, but I was told it was a good product and fairly easy to setup. On top of the DNS Server itself, I need a local DNS caching agent. At this point I had found PowerDNS’s recursor component, along with information that they could be setup side by side, so I figured I’d give it a shot.
