Dynamically Switch Between Multiple CDNs to Improve Performance and Reliability
Imagine yourself surfing the web. You click on a link, wait for the page to load ... Still loading? You lose patience, quit that page and try another link. This slow load time is a death knell for a website, particularly since today’s users are impatient and expect to access content quickly, regardless of device or location. As developer, you need to make sure the content - particularly images and videos - loads as fast as possible, in the best possible quality, to increase the chances of engaging users. No matter where the users are located, delivering a fast, consistent web experience is critical to improving the user experience. Improving the performance of images can significantly improve the page load time but is complicated, as you have to:
- Minimize, or at least reduce, the number of bytes used to represent the content, and
- Improve the efficiency of delivery, measured by availability, latency, and throughput.
- Integration of multiple CDN solutions can be time-consuming
- Greater complexity of maintenance and administration
- Total cost of ownership (multiple vendor contracts)
- Operation overhead that can take the focus away from the core business
I think we will see a lot more use of CDN over the next couple of years. Already when developing websites you can deliver frameworks like Bootstrap, Font Awesome and the latest JQuery over CDN. We also see video embeds from Youtube to reduce bandwidth and loading time. I think the aspect of delivering content via a CDN will obviously speed up websites that are hosted in other parts of the world – but it will also do it locally. With how google ranks pages for SEO loading time is a big thing, so those extra seconds matter.
