How Does Netflix Manage Growth?

• Build an internal CDN (Open Connect) to

distribute content

• Build a global network to manage cache fill to

the edge

• Open peering at common exchange points
• Continuous improvements to CODECs to

minimize data usage without sacrificing user experience

• Adaptive streaming
• Preload all bitrates to minimize calls to Origin

How Does Netflix Help You Manage Growth?

• Provide free cache servers for partners to

deploy in their networks

• Servers are zero-touch
• Long-range forecasting
• Per-subnet traffic analysis
• Troubleshooting data (TCP Retransmits, Play

Delay)

• Efficient cache fill in a set, off-peak window

The Future

• Traffic will continue to grow exponentially

even when subscriber growth levels out

• Content will continue to move to the edge,

while compute moves to the cloud

• Providers that anticipate growth and

proactively increase capacity will have the happiest eyeballs
