of Hybrid CDN
As the world moves towards digitalization and online
platforms; keeping the user experience on top while delivering
content has become a major issue to tackle. According to the
most recent Cisco Systems Visual Net working Index Report:
• Global IP traffic will have increased 127-fold from 2005
to 2021 with a CAGR of approximately 24% from 2016 to
2021 and with a quantity of 278 EB per month.
• Rush-hour traffic usage has grown 51%, whereas average
traffic usage has grown 32% in 2016, increasing the daily
bandwidth usage gap.
• Globally, IP video traffic will be covering 82% of all
consumer traffic, and every second 1 million minutes of
video content will be crossing the network by 2021.
• CDN infrastructures have already been carrying 52%
of the global traffic in 2016, and this amount will be
increased to 71% in 2021.
The amount of data transferred was not always at these
tremendous levels, and it is without a doubt increasing
exponentially. The numbers above show the increase
in network usage and data delivery, showing why CDN
infrastructures have become essential for web and OTT
applications. To put it another way, Hybrid CDN is an
extensive solution to stream video content any time, over
any network and to any device.
A GLANCE AT THE CONTENT DELIVERY
Even though CDN technologies have existed for around
15 years to improve web performance through caching
solutions, they have improved over time and recently,
developing technologies have made another concept possible:
the hybrid CDN.
Getting from the starting point to the ideal infrastructure
that combines self-managed CDN with third-party CDNs has
been a process of continual evolution, as described below:
1. Single Origin Infrastructure
In the early days of online platforms, I T and operations
tried to deliver their web content, images, and videos
to all of their audience via their own data centers. All
the data was stored in the single data center, and all the
audience was connecting directly to that address. This
infrastructure had many disadvantages, from needing
reliable experts in-house 24/7 to downtimes, latency, and
buffering problems due to users’ geographical locations
and the number of simultaneous users.
