Content Delivery Networks (CDNs) can be used in concert with OpenShift to rev up the performance and availability of your websites.
OpenShift’s auto-scaling feature equips web applications to handle increases in requests for site content, which may or may not be dynamically generated. CDNs, also known as Content Distribution Networks, can help to reduce some of the load on your OpenShift application servers and improve your site’s performance by caching static resources such as images and scripts and serving them up from the closest location to your users, from a global network of servers distributed across the internet.
CDNs can also help to protect your web applications by detecting suspicious behavior and blocking offending traffic.
There are many CDNs to choose from, such as Akamai, CloudFront, Incapsula, and CloudFlare. In this blog post, I will show how to add the CloudFlare CDN to an OpenShift-hosted website with a custom domain. CloudFlare has a free tier, so anyone can use it.
