Cloudflare is a content delivery network (CDN) that increases the performance and security of every website on its network, protecting from a broad range of threats and attacks. Over 7,000,000 websites run on the Cloudflare network—ranging from individual blogs to e-commerce sites to the websites of Fortune 500 companies to national governments. Cloudflare powers almost a trillion monthly page views—more than Amazon, Wikipedia, Twitter, Zynga, AOL, Apple, Bing, eBay, PayPal and Instagram combined—and over 25% of the Internet’s population regularly passes through our network.
NetWeaver is proud to work alongside Cloudflare as an Optimized Partner, and we offer the benefits of this to all of our hosting customers – free of charge.
We run a Cloudflare Railgun server on our network. When you enable Cloudflare on your account you’re automatically enrolled to make use of this. The Railgun server enables the caching of even dynamic websites and speeds them up dramatically.
Railgun uses a new caching mechanism based on comparing page versions to determine what needs to be transmitted across the Internet to the Railgun Sender. Using this mechanism Cloudflare is able to achieve typical 99.6% compression (taking, for example, a 100k web page down to 400 bytes) and a speedup of over 700%. In fact, the compressed data is often so small that using the binary Railgun protocol the entire response fits inside a single TCP packet.
All traffic is also TLS encrypted to ensure that your, and your users’ data remains secure. As the connection is permanent, there is no delay opening the connection.

Faster web performance
Cloudflare runs 149 data centers strategically located around the world. When you sign up for Cloudflare, we begin routing traffic to the nearest data center.
As your traffic passes through the data centers, we intelligently determine what parts of your website are static versus dynamic. The static portions are cached on our servers for a short period of time, typically less than 2 hours before we check to see if they’ve been updated. By automatically moving the static parts of your site closer to your visitors, the overall performance of your site improves significantly.
Cloudflare’s intelligent caching system also means you save bandwidth, which means saving money, and decreases the load on your servers, which means your web application will run faster and more efficiently than ever. On average, Cloudflare customers see a 60% decrease in bandwidth usage, and a 65% in total requests to their servers. The overall effect is that Cloudflare will typically cut the load time for pages on your site by 50% which means higher engagement and happier visitors.
Broad web security
At the beginning of 2016, Cloudflare experienced and mitigated against some of the largest distributed denial of service (DDoS) attacks ever seen. As attacks like these increase, Cloudflare is stepping up to protect websites.
Cloudflare’s security features offer a broad range of protection against attacks such as DDoS, hacking or spam submitted to a blog or comment form. What is powerful about our approach is that the system gets smarter the more sites that are part of the Cloudflare community. We analyze the traffic patterns of hundreds of millions of visitors in real time and adapt the security systems to ensure good traffic gets through and bad traffic is stopped.
In time, our goal is nothing short of making attacks against websites a relic of history. And, given our scale and the billions of different attacks we see and adapt to every year, we’re well on our way to achieving that for sites on the Cloudflare network.
Any website can deploy Cloudflare, regardless of your underlying platform. By integrating closely with NetWeaver, we make the process of setting up Cloudflare “1 click” through your existing NetWeaver control panel. Just look for the Cloudflare icon, choose the domain you want to enable, and click the orange cloud.
