Cloudflare has built the next generation Content Delivery
Network. Our platform was designed and built to integrate emerging
technologies to ensure our customers receive the most advanced
protocols on the web; today and tomorrow.
We have built a global network designed to optimize security,
performance and reliability, without the bloat of legacy technologies.
The result is a CDN that is easy to setup, more affordable, and
performs better than any CDN you’ve tried before.
Cloudflare caches your content across our
global network, bringing it closer to visitors from every region.
With Cloudflare’s content delivery network, you’ll never be charged for bandwidth. This means predictable monthly bills, regardless of the amount of traffic served from our edge.
Peering has become a
core requirement of the global Internet. Removing an intermediary network
that’s in the path of a DDoS attack can actually help keep the Internet
operating cleanly. Plus, it gets your content closer to your visitors to
provide a faster experience. At Cloudflare, we are dedicated to peering.
So much so that we joined our 100th
Internet Exchange point in January of 2016 and now peer at 200+ locations.
Cloudflare and Baidu have partnered to make Internet applications faster and more secure in China and around the world. The result is a significant increase in availability for China traffic and over 30% decrease in latency.
Cloudflare has designed its CDN without the legacy of the last 15
years. Our proprietary technology was built to continuously adapt and
integrate emerging technologies to meet future needs of everyone’s
Cloudflare has exclusively used SSDs from the beginning to
significantly reduce power consumption while increasing read performance.
Cloudflare deploys smaller footprints in more locations. This allows
us to take advantage of innovative deployment, power, and cooling
strategies. As a result, we have been able to optimize the processing
of high volumes of traffic through our network.
By default, Cloudflare only caches static files. However, Page Rules
can be utilized to set more files as cacheable. With Enterprise
features like Query
String Sort, Cloudflare will first sort the query strings in a
URL into a deterministic order before checking cache for the resource
or requesting it from the origin. This feature is especially useful
for API servers, which often rely heavily on multiple query string
Cloudflare’s global Anycast network powers our DNS and other
services. With Anycast, multiple machines can share the same IP
address. When a request is sent to an Anycast IP address, routers will
direct it to the machine on the network that is closest.
Anycast allows us to save significant network latency while creating
an extremely resilient network. The nature of Cloudflare's Anycast
network is that we inherently increase the surface area to absorb such
an attack. A distributed botnet will have a portion of its denial of
service traffic absorbed by each of our data centers.
With built-in load balancing and automatic failover, the Cloudflare
network has been designed to withstand losing 50% of the network
without impacting service availability. Customers who sign up for our
Business or Enterprise plans also receive a 100% uptime SLA.
Cloudflare believes that anything connected to the Internet
should be fast. Because of Cloudflare’s technology, we’ve been able to
build a CDN that is available to any website online.
beginning, we worked to minimize the costs of serving every byte.
Wherever possible, we use our own custom-built systems that are
designed for this purpose. We buy our bandwidth through the wholesale
market, which means we’re paying for the size of our pipe, not for each
byte we serve through it.
We also peer with other networks wherever possible in order to
drive the cost of bandwidth as close to zero as possible. We never
charge for bandwidth and are committed to always offering a FREE
version of Cloudflare with at least today’s feature set.
Cloudflare’s premium plans offer even better services at
reasonable prices. We hope you love the service and choose to
