Scaling with cloud-burst
CDN Broker is ideal for controlling hybrid cloud CDN platforms with on-premises CDNs augmented by public CDNs to efficiently manage traffic bursts, such as during major live sporting events.

A hybrid cloud architecture contributes to greater environmental sustainability since it allows on-premises CDNs to be sized for typical daily demands, rather than occasional bursts. By right-sizing the on-premises CDN, wasteful idling of CDN caches can be avoided.
Example of hybrid cloud workflow
CDN Broker can precisely control cloud-burst switching to prevent traffic congestion and any associated deterioration in viewing quality. The following steps link to the schematic above:
Step 1 |
For premium content, the private CDN is preferred to keep costs low, quality high. Capacity is available, so the CDN Broker directs traffic to the Private CDN |
Step 2 |
Demand rises unexpectedly. Max capacity is reached on the private CDN. |
Step 3 |
CDN Broker automatically re-routes traffic to the next best CDN, for example Public CDN A, without interruption. |
Step 4 |
Private CDN is continuously monitored. When space is available on the Private CDN, sessions are moved back to the private CDN to save cost. |
