Symptoms:
- There's a need to replicate data across servers in various locations globally.
- How can I ensure my files uploaded in the United States are also readily accessible around the world?
Cause:
Developers aim to optimize file availability by hosting content on servers closer to their users. This minimizes latency, resulting in faster and more efficient file delivery.
Resolution:
Cloud Content Delivery (CCD) uses its Cloud Delivery Network (CDN) to automatically synchronize and replicate files to multiple servers worldwide, ensuring global accessibility with minimal delays.
An example of a user in Japan downloading files from CCD:
- First file request from a user in Japan
- CCD/CDN doesn't find the file on Japan servers
- CCD/CDN retrieves the file from the US
- CCD/CDN stores a copy in Japan
- The file is delivered (first time slower)
- Following requests from Japan will be much faster.
