A Word About CDNs
• CDN = Content Delivery Network
• Ever heard of Akamai?
• How does a CDN work?
www.bitstreamfoundry.com
CDN Operations
• Static assets (like media) are put closer the point of use/download
• Avoids potential excessive latencycosts
• Greater likelihood of fat pipe near you
• Content comes with cacheabilityheaders (e.g., public, max-age > 0)
• Avoids unnecessary downloads (local cache & HTTP 304 returns)

Another Benefit of CDNs
• Browsers limited to six concurrent open HTTP connections per domain (per RFC2616).
• Name/URL based
• CDN typically use another name/URL (e.g. *.akamaihd.net instead of .sharepoint.com for SPO)
• Add another URL and add six more concurrent downloads!

• Microsoft has easyinstructions
• Many common libraries andframeworks are hosted in CDNs
