Content Delivery Network
Oikos Networks’ expert technicians are daily immersed in the infrastructure of the Internet, supporting our clients worldwide and keeping their online businesses running.
What is a CDN?
CDNs are widely used in today’s online environments, boosting the transmissions of a major fraction of all Internet traffic in the world. A content delivery network is a distributed network of server nodes that can respond directly to end user requests for web content. The network acts as an intermediary for the content server to help balance traffic loads required to deliver content such as web applications and streaming data.
This system of networked servers is scattered over multiple physical and network locations, to better respond to end user requests for fast, secure delivery. Without CDN support, origin servers that generate initial contents must respond to each and every end user request. With a large load of requests, origin servers might fail and services might be made unavailable quickly in applications and websites that serve many users simultaneously.
What are the benefits of a CDN?
CDNs (Content Delivery Networks) serve almost half of the world's Internet traffic today. They are employed everywhere and aid in efficiently delivering content over the web. With over 3 billion internet users worldwide, small, medium, and large corporations are depending on CDNs to fluidly present customers with uninterrupted experiences of their online services.
The reason CDNs became pervasive and successful in modern Internet websites and applications is that: the Internet did not originally intend to support all aspects of modern communication today. The massive amount of data, high definition video, flash sales, and large downloads were not in the original designs of the Internet when it was first built. CDNs arose as a supplementary solution to the problem, built to speed up the Internet, deliver large media content at scale, and enable customers to fully partake in the user experiences that will provide a company's success.
In specific terms, CDN technology should provide the following primary benefits to a business:
When requested content is cached (pre-saved) by a CDN’s servers, end users will get that content by connecting to the nearest CDN server rather than waiting for their request to go directly to the origin. This results in a significant speed improvement for the end user. For example, let’s say that your company, releases its new products for online orders. Your clients worldwide will all go online to make their orders. If your company isn’t using a cloud content management system, the request from each end user must go all the way to your server and back. However, if your company uses a CDN and has pre-warmed its content across the CDN, each user can access the new content from servers directly in their city, saving their data hundreds or thousands of miles in round-trip time.
When traffic loads peak at millions of requests per second, even the most powerful origin servers would be put to the test. Without a CDN, all this traffic has to be absorbed by a content provider’s origin infrastructure. This can cause the origin to fail, resulting in a terrible end user experience and lost business. That’s when CDNs, with their massively distributed server infrastructure, are of immense value. Advanced CDNs, with their highly distributed architecture and massive server platforms can absorb tens of TBps of traffic and make it possible for content providers to stay available to larger user bases than otherwise possible.
As the volume of high-value data and transactions on the Internet continues to grow, so do the forces of attackers looking to exploit it – and these forces are costing organizations big money. According to a report by the Ponemon Institute of Cyber Crime, in 2015 businesses around the world suffered average losses of $7.7 million due to cybercrime. Along with crimes committed by malicious insiders, DDoS and web-based attacks were found to be the costliest.
Given the increasing volatility of the Internet threat landscape, helping to secure websites is a critical CDN requirement. Today’s most advanced CDNs, such as Oikos Networks, have made information security a core competency, providing unique cloud-based solutions. CDNs should protect content providers and users by mitigating against a wide array of attacks without malicious entities ever compromising delivery and availability.
As carriers of nearly half of the world’s Internet traffic, CDN providers generate vast amounts of data about end user connectivity, device types, and browsing experiences across the globe. They can expose this data to their customers, thus giving them critical, actionable insights, and intelligence into their user base. In the case of Oikos Networks, this includes Real-User Monitoring and Media Analytics to measure end-user engagement with web content, and Cloud Security Intelligence to keep track of online threats.
