Introduction to Content Delivery Networks (CDNs)

In today’s digital age, website speed plays a crucial role in the success of online businesses.

Slow-loading websites can lead to high bounce rates, poor user experience, and decreased search engine rankings.

Content Delivery Networks (CDNs) offer a solution to this problem by accelerating website speed and performance.

CDNs are a network of servers distributed across various locations worldwide, designed to deliver web content more efficiently to users.

By caching content on servers closer to the user’s location, CDNs reduce latency and speed up the delivery of web pages, images, videos, and other media assets.
