It’s important to note that unless you have a dedicated development team and a high traffic website delivering large amounts (GB) of content per second, the time, complexity and cost to build your own CDN would not be justified.
If you’re a large company that fits the above criteria, these are the steps involved in building your own private or hybrid CDN:
On-Site or Cloud — this applies to both your origin server and PoP edge servers.
You’ll need to weigh factors like what kind of traffic you have and whether building your own infrastructure will be cost effective.
ISP — your chosen ISP will need to be able to efficiently route each browser access request to the closest PoP.
Origin Server & PoP — in-depth analysis of your website’s global traffic patterns will be crucial at this stage of selection.
CDN & Caching Software — make sure that the configuration is flexibly suited to your needs, now and in the future.
Your development team will want to keep a close eye on ensuring it integrates well with your website for effective PoP performance and fail safe security.
