The majority of web traffic today is served through CDNs, and the need for CDN services is only growing with the proliferation of streaming services, e-commerce, and cloud-based applications that require increasingly high performance. CDN providers operate their own network points of presence (POPs), and cache their content in third party-owned data centers, or a combination of both. Since very few CDNs have POPs all over the world, companies will use a number of different CDNs to deliver their content to the end-users.

Network providers, connecting with each other at various PoPs all over the world, are the foundation of the entire internet, and interconnected data centers allow you to access them as quickly and locally as possible.
The demand for content flowing from large-scale gaming and streaming services is driving hyperscale expansion. Because delivering this content without a loss of quality–or a subpar customer experience–requires processing and distribution at the edge, hyperscalers need to supplement their footprint with interconnected points of presence that can optimize content delivery.
Customer expectations have shifted toward seamless and fast content delivery anywhere, anytime, and content streaming providers are scrambling to accommodate new levels of demand, pushing IT teams to establish data delivery methods that enable ultra-low latency and always-on connectivity.
