Being around for a long time, CDNs are now an essential part of modern Internet service. A CDN helps a content owner deliver content at high speeds. This is done as a distributed system, where different servers are deployed in different datacenters worldwide and share the same network path between them. Many organizations are entering the CDN industry as businesses realize the importance of CDNs.
The Internet is becoming very important, and relying on one CDN is becoming a liability. Compromise of the Internet, either by attack or security failure, could lead to financial loss for a company. Instead of placing the company’s trust and reputation in one CDN, it is better to spread the workload among multi-CDNs. This is due to the high failure rate of single CDNs. There is no way to know if one of them will go down and cause a considerable disruption of services.

Diverse content and sites are being added daily, so managing all this content within one location becomes difficult. Businesses want to use Multi-CDNs, while also retaining the benefits of single content delivery across their domain.
Multi-CDN is a complementary solution for content delivery networks. This system distributes a site’s content over several different CDNs to ensure that each delivery system has enough capacity to deliver the content. Multi-CDN works by dividing the workload into smaller pieces and distributing them among multiple CDNs. It can also increase network redundancy and reduce downtime due to network issues. If one of the CDNs goes down, Multi-CDN will remain operational enough to handle additional requests.
A Multi CDN is a system that uses multiple CDNs from different service providers as a single network. This solution can help reduce the number of websites that prompt loading errors, and it can help achieve better performance for a website than in a single CDN system.
No CDN offers universal coverage, so relying on multiple providers increases the reliability of CDN delivery by permitting broadcasters to provide more widespread coverage. Multiple CDNs also give your PoPs a more comprehensive array of providers.
With additional distribution, your video can reach regions where individuals can locate it. You can also set up an alternative support system if your network provider’s servers become overloaded or offline.
Multi-CDNs work by directing traffic to different CDNs in the network. In multi-CDN implementations, the specific criteria for making routing decisions differ. Some common multi-CDN strategies include:
Multi-CDNs are primarily used by businesses that can handle the additional complexity and cost. Each step of configuring Multi-CDN will result in a tradeoff between security, latency, availability, ease of implementation, and the existing infrastructure. Therefore, it is essential to weigh the prospective benefits of implementing a Multi CDN strategy before deciding. Before implementing a Multi CDN strategy, here are some questions to ask yourself:
Most CDN resellers do not offer a managed multi-CDN service, as they are only partnered with a single vendor. But GlobalDots is one of the few multi-CDN resellers. GlobalDots is partnered with all the major providers to provide the most comprehensive coverage for your CDN needs. Provide you with a cost-effective plan of 2-4 CDN vendors, including a daily report and the possibility of adding new vendors every month.
Provide you with a dedicated and insightful dashboard on your observability platform to monitor and measure the performance of your CDN architecture. And provide you with configurations as code that allow simultaneous changes to all CDNs at a single action to ensure that sound changes are implemented rapidly.
In conclusion, a Multi-CDN architecture is recommended for any online business wishing to expand its reach and improve service. Having a multi-CDN vendor network in place will allow companies to be more agile and flexible in the short term by adding capacity at any time. However, if there isn’t a dedicated in-house function to manage this architecture, it’s necessary to turn to a CDN-specialized technology partner who might offer this managed service. A good technology partner should give you lower pricing per GB and overall cost efficiency than a single CDN and save you the need to configure yourself for cost or performance optimization. GlobalDots helps you leverage your CDN investment by allowing you to optimize your existing assets and by keeping you ahead of the competition.

With the increasing demand for speedy and efficient content delivery, advanced solutions like the Content Delivery Network (CDN) have emerged. But what does CDN actually mean? Essentially, it’s a network of strategically positioned servers aimed at enhancing the speed and dependability of delivering content to users in different locations. These servers store cached copies of […]
