Most websites and applications that we interact with every day are run out of one physical location, but content on the site (like images, text, and video) still needs to travel over wires to the entire world.
For example, if a website’s servers are based in New York City, people in Boston will get the content faster than people in San Francisco or Tokyo. The farther away customers are from a company’s data center, the slower the website or application loads — creating an inconsistent and frustrating user experience.
Content delivery networks can help solve this problem.
