Content Delivery Networks (CDNs) help ensure customers enjoy lightning-fast digital experiences by storing and delivering static assets at the network’s edge. The CDN uses these edges as a component of its extensive worldwide server network. When an end-user needs access to a domain outside their network, CDNs may utilize their better network peering capabilities to facilitate this. While content delivery networks (CDNs) may significantly increase the availability of your apps or services. Choosing the correct CDN provider can be challenging. This post will look at what criteria should be use to evaluate CDN services. The complexity of required infrastructure is rising due to the demands of current websites, and choosing a Global CDN based on whether or not it seems quicker than your origin server is insufficient. To help you evaluate a CDN provider, we’ve included sample questions in the following sections.

1.First, the Lag Time of DNS

Complex DNS configurations used by certain CDN providers may significantly reduce speeds. The slower DNS response time may give the impression of a shorter wait time. DNS performance at the last mile and for the end users differ significantly from what is seen in the backbone. Backbone monitoring uses resolvers that are physically proximate to the computer doing the tests. At the same time, end users depend on the DNS resolvers of their Internet Service Providers (ISPs) or Public Resolvers.

2.During the Third Interval of Waiting

Wait time is valuable for identifying capacity problems and misconfigurations on your origin server or the Global CDN Providers provider’s network. The time users wait before they see your content might tell you. Whether it is being deliver from the edge or if a request must be make to your origin server. As you’re paying for it, shouldn’t your stuff be accessible on edge? Different CDNs provide varying degrees of speed for “hot” static assets—those requested 100,000 times or more in the previous hour (versus only a few times per hour). This is because content distribution networks (CDNs) are collaborative spaces where the most in-demand resources need the quickest delivery times. The throughput of the CDN test should be greater than that of the origin, regardless of the amount of the files being sent.

3.Tracking

Inaccurate IP addresses may lead to incorrect client assignments even though many CDNs employ commercial geo-mapping databases to map their customers’ locations appropriately. You should do it from your monitoring location to verify that you are not incorrectly map.

Conclusion

You know what to look for in a CDN Service providers. You can free up resources formerly spent on managing static assets and offer superior content delivery to your audience. Choosing a content delivery network (CDN) and getting set up on their platform is just the beginning. Maintain constant contact with your CDN supplier and keep an eye on their performance indicators compared to the origin. As a result, you and your supplier may form a mutually beneficial partnership. That will ultimately help your business and its customers.
