…(CDN) is a service that replicates online content and seeks to optimise delivery network conditions across multiple geographies to provide a fast user experience.
When creating a website or content that spans multiple countries and continents it is essential for the user experience that content is delivered in a timely manner. By using a content delivery network your video, software download or web pages are deployed using the nearest available node or network that the content delivery network resides on.
The localisation of content ensures that any user accessing your website or media gets a fast loading user experience without delays introduced by accessing content in another continent.
There are compelling advantages for any organisation that wishes to implement a content delivery network within their web based strategy. We have listed out some of these advantages below to help guide your decision.
CDNs use a technology called Geo-location; this means that users are sent to the nearest network node to browse the media you’re trying to deliver.
Many website frameworks such as WordPress or Drupal are easily integrated into a CDN using tools provided by the CDN provider.
Frequently accessed content such as images, flash files, video and software downloads are copied and hosted across the globe on the CDN providers network in accordance with regional demand for that service.
Content delivery networks are cloud based this allows your organisation to leverage the efficiencies of the cloud computing model in terms of short term contracts and pay as you go services.
SSL or Secure Sockets Layer is the encryption mechanism used to secure communications between a website and a client’s internet browser. Typically SSL provides a high burden on websites in terms of processor load. By offloading this element to a CDN provider your static and frequently accessed material will improved when clients interact with your website using a HTTPS / SSL connection.
With any technology deployment there are things to keep in mind and consider. We have listed out potential pitfalls to consider when deploying a content delivery network solution.
Using a CDN adds complexity to your system set up, if you’re a novice always engage with a consultant to aid your deployment and provide technical input.
Test the provider
Check the provider’s network by testing response times to ensure that content is delivered in a timely manner and delivers a performance boost against your current deployment.
Cost and scope creep
Depending on the content being served always ensure that it fits within your budget and does not incur further costs. Scope creep is where costs may be applied for areas not originally budgeted for, an example could be a viral video that receives an explosion in traffic.
