Learn how to use Google Cloud CDN Content Delivery Network – Blog
CDN services were created to alleviate network congestion by providing rich online content, such as video and graphics, across the internet. It is similar to a traffic jam. It was just too slow to move material from centrally located servers to individual users. Text, images and scripts are increasingly being stored in CDNs. Software downloads, portals, software, documents, and software are also available in CDNs. Let’s learn how to use Google Cloud CDN Content Delivery Network!
What is Google Cloud CDN?
Google cloud content delivery network (CDN), is a collection geographically dispersed computers that speed up online content delivery by bringing it closer to consumers. Caching is a technique that temporarily stores copies of information in data centers around the world. This allows you to access internet material faster via a web-enabled device, or via a server close by.
CDNs cache web pages, photos, videos on proxy servers near your physical location. This allows you to view a movie or download software without waiting for the content to load.
A CDN is similar to an ATM. Cash machines are available at almost every corner so you can quickly get money. ATMs can be found in many places so there is no need to wait in long bank lines. CDNs can also offer enhanced protection for websites against malicious actors, as well as security concerns like distributed denial of service (DDoS), and other security concerns.
CDNA example: A large percentage of internet content is delivered via CDNs. Here’s an example:
If you were to visit New York to view the website for your favorite London store, it would take a while for the content to load. This is because the request has to travel across the Atlantic Ocean. A CDN stores a cached version the London website content in multiple locations around the globe, which is also known as “points of Presence” (PoPs). These PoPs have their own caching servers, and are responsible for delivering the content to you in New York.
You get a faster, more efficient web experience when content is delivered from a server near you.

CDNs provide a large amount of online material. Here’s a simple example: If you were visiting New York and wanted the website of your favorite retailer in London, it would take a while to load because it would have to travel across the Atlantic Ocean.
A CDN would cache London’s website’s content at different locations around the globe, which is known as “points-of-presence” (PoPs). These PoPs are responsible for providing material close to your location in New York. A server closest to your location will provide you with a faster and more responsive online experience.
What is a CDN? It reduces latency. Latency is the annoying delay that you experience when you try to access a website or stream of video before it loads fully on your device. It can feel like a long time, even though it is measured in milliseconds. Some content delivery networks reduce latency by reducing distances that the content must travel to reach you. CDNs that are larger and more widely distributed can deliver web content faster and more reliably, by placing the content as close as possible to the end user.
Let’s say you have a weekend and you want to relax and stream the latest Hollywood movie releases. The CDN will find the best server on its network.
