Use CloudFlare with Rackspace
This article explains why you might want to use Cloudflare® with Rackspace.
Content delivery network
When you sign up for Cloudflare, you automatically begin to cache files on Cloudflare’s content delivery network (CDN), even on free plans. As your website visitors request static files (such as images, cascading style sheets (CSS), and other files) from your site, those assets are cached on Cloudflare’s CDN edge nodes in a global network of caches. Then, those assets are served from the Cloudflare edge nodes instead of your Rackspace servers. This approach requires less bandwidth and delivers content faster. Cloudflare helps figure out which pieces to cache and which it should serve fresh each time.
Cache the right content
Cloudflare also enables you to set individual page caching rules. For example, if your “About Us” web page rarely changes, you can configure Cloudflare to cache it in perpetuity. That page will always be cached on and delivered by Cloudflare’s edge nodes, rather than your servers. This approach lowers your bandwidth and reduces the load on your servers.
If your entire site is static HTML, you can cache all of it by using Cloudflare. When you cache a static site in its entirety, your servers are rarely required to do any work, which greatly reduces the risk of a server crash.
With the Always Online feature, Cloudflare automatically caches a limited copy of your site so that if your servers ever go offline, your customers see the limited version. Controlling the experience that your customers have during a server issue can be very important.
Cloudflare began as a security company and is still strong in this area. Cloudflare offers free Secure Sockets Layer (SSL) connections from Cloudflare to your users’ browsers. This technology can help keep connections secure. If your servers are encrypted with SSL, you can encrypt the connection completely from end-to-end, which is a security win for your customers.
On higher-tiered plans, distributed denial-of-service (DDoS) mitigation and web application firewalls enable you to protect your site against attacks, keeping your customers online and secure.
Get started with Cloudflare
You can easily set up Cloudflare by using the following steps:
- Sign up for an account at cloudflare.com.
- Specify the domain or domains that you want to import.
- Cloudflare finds all of the applicable records so that you don’t lose any functionality when the name servers are switched.
