Multiple CDNs
one interface, and one contract.

Warpcache has designed a turn-key multi-CDN solution that enables businesses to get more out of their Content Delivery Network setup. We transparently combine the strongest points of multiple CDNs into one big network. The full network can easily be controlled through our easy to use graphical interface or super simple API.

Leverage the power of your website, not your loading bars. Content should be there for your customers to consume, and above all to enjoy – but as more aspects of daily life take place online, web users are willing to wait less and less time for content to load. Performance issues throw a spanner in the works and negatively influence your customer’s loyalty, retention and brand perception. That awesome new video or that cool new app might have your customers checking out instead of checking in. By improving the performance and reliability of your content delivery, you’ll keep your customers at your side.

Traditional solution: CDNs

Traditional hosting: content is served from the Origin (in green).

Traditional hosting: content is served from the Origin and has to travel a great distance to reach users.

The most common solution to accelerate content from a networking perspective: using a Content Delivery Network (CDN). Enlisting the services of a single provider lets your content travel over their servers and infrastructure, caching it closer to the user and decreasing the ‘journey time’ of your data. While using a CDN is a great step towards optimising your performance game, it also brings new challenges for businesses:

  • No single CDN is the fastest everywhere on the globe; the geographical coverage differs per provider. Each provider has Points of Presence (PoPs) in different regions and different places, but may not be present in others. The quality of your customers’ experience will differ depending on their proximity to such a PoP so it’s paramount for your business to select the provider closest to your customers.
  • No single CDN provider optimises all file types equally. Depending on whether you’re sending large or small files, you want to look at the optimal throughput or the response time. Some CDNs facilitate throughput better, others optimise for response time – an important factor to consider when selecting your CDN of choice.
  • All CDNs suffer outages, and while you might not notice some, your users will. Without a backup plan, an outage means your site is down, unavailable or performing poorly. Experience may differ depending on the type or magnitude of an outage: major outages will cause your CDN to go down globally, but smaller micro-outages are regional and more confined. Often the latter go undetected, despite having a huge impact on a smaller portion of your customers.

Selecting a single CDN that fits your business needs is complex if you don’t want to make concessions, and could potentially become a costly endeavour. While key regions and file types can identify the preferred CDN for your content, the service on which your business relies is still a single point of failure. If your CDN is offline, you are too.

Why multi-CDN?

CDNs have PoPs all over the world

CDNs and their Points of Presence (PoPs): information is cached at locations closer to users.

In an attempt to solve the challenges that come with using a single CDN, businesses can opt for a so-called ‘multi-CDN’ setup – a superior solution compared to ‘mono- CDN’. The setup combines the networks of multiple providers into one large network, and based on continuous performance tests the most suitable provider for each of your users is selected.

The advantage of having multiple CDN providers in one portfolio is that your business can benefit from their strengths, without having to worry about their weak points. For example, the coverage of one CDN is no longer a concern when another CDN is present in a region where the first is not. The same goes for throughput or response time optimisations – depending on the file type the fastest route will be chosen, and your content is automatically served out by the most suitable CDN for that type, at that moment. A single CDN does not provide the best fit for all situations, but a multi-CDN setup routes over the one that does, guaranteeing a tailored fit for each single request. This selection mechanism also steers you clear from outages: whenever a CDN’s performance is degraded or when it is not available at all, that particular network simply won’t be chosen to serve your traffic. Your business no longer relies on the availability and performance of a single CDN. Read more about how multi-CDN can mitigate content delivery issues in our blogpost here.

Combining the networks of multiple CDNs increases the amount of accessible PoPs

Multi-CDN combines the networks of multiple CDN providers into one.

As a solution, multi-CDN is preferred over a single CDN setup, though it too comes with some challenges for businesses:

  • The configuration sync between multiple CDNs is complex and not easily implemented. The technical challenge of such an undertaking requires know-how and development time.
  • Scattered support isn’t helpful in times of need. Providers are limited and can only assist with issues concerning their own environment when something is awry.
  • The effort of negotiating with multiple providerswhile suffering a loss of bargaining power – as your traffic is sliced up between multiple parties, a bulk deal is off the table.

This is where we come in.
