Save bandwidth and be resistant to DDoS attacks

According to this year’s research conducted by Cisco Visual Networking Index in 2019 Internet data traffic will reach two zettabytes (one zettabyte = sextillion bytes) — which is equivalent to the total traffic in the years 1984–2013. Service owners are already looking for savings on bandwidth, using, among others, a CDN (Content Delivery Network), which accelerates loading of page elements and facilitates reducing the use of data transfer.

The idea of CDN involves placing static page elements in the cache, and serving them via a network of servers distributed around the world. Last year 39% of the total Internet traffic was passing through CDN, and it is estimated that by 2019 this number will increase up to 66%. This service is offered by free e.g. by American CloudFlare, one of the fastest growing startups in the world, the winner of The 2015 Crunchies Award for Best Startup (it defeated, among others, GitHub and OpenDNS), which handles 65 billion Internet page views per month.

Last year 39% of the total Internet traffic was passing through CDN, and it is estimated that by 2019 this number will increase up to 66%.

CloudFlare’s method is to direct the movement of the service through 62 data centers, which are located in various locations around the world. CDN network automatically caches static files (i.e. caching). As a result, they are being served closer to the Internet users, while dynamic content is being loaded from the server on which the website is stored.

Thanks to the Anycast technology used by CloudFlare, Internet users are redirected to the data center closest to their place of residence, e.g. a user from London will be redirected to the server located in a server room in London, and a user from Tokyo to the server in Tokyo, etc. Thanks to this solution, a page loads twice as fast, and the use of the bandwidth may be up to two times lower.

Using CloudFlare as a solution for complex websites which serve many static files, you can count on savings of on averagea few dozens percent. What is also interesting, CloudFlare’s basic version is available completely for free. However, expertise is necessary for its proper configuration, and in this aspect, as an official partner of CloudFlare, we offer you our help.

In addition to real savings on the use of bandwidth, CloudFlare offers a tempting service of free DDoS protection. The service special filters automatically detect attacks on each page in their networks, stopping them not only on the given site, but also on all pages being part of CloudFlare community. CloudFlare network “learns” each of new attacks, updating security for all its pages.

This American company became famous especially thanks to its resistance to the greatest observed DDoS attacks in the history of the Internet, estimated at 400 Gbps. Currently hundreds of thousands of websites use CloudFare, from singular blogs to e-commerce Fortune 500 services to government websites. The company itself is valued at over a billion dollars. Hostersi, owner of the brand Admin365, is an official partner of CloudFlare.
