Content Delivery Network
The Bearded Buddies - Andrei, Vik, Despick
Current situation
- At the moment, loading our e-commerce site is painfully slow..
Depending on where the sites are accessed from, load times can be up to 10 seconds
With a CDN:
1 out of 4 customers is sure to abandon a webpage that takes more than 4 seconds to load.
- large distributed systems of servers across the Internet
- contains static data
- web objects and assets: javascript, css, images
- images, documents, video, ebooks etc...
- most content in a website is static, which is served much quicker
What is a CDN?
- necessity to divide the calls between static content and the application
- used to serve static (and personalized) content to different places of the world
- because the content it serves is static, the CDN can cache all of its content
- saves bandwidth and requests made to the application webserver
- can be optimized for the browser with techniques like: image formatting, minifying css and js
- not in a cloud but distributed accross the world
-
more secure because of its distributed nature
- harder to try DDoS attacks
- easier to implement limitations
Components
- can use various optimizing algorythms
- Dynamic Site Acceleration services
- special handling when serving videos
- serving mobile content (mobile acceleration)
- analytics
- tools for tweaking performance, responsiveness and bandwidth
