I have a very basic question about CDN - BlobStorage and WebRole, and perfrormance.
I have a very simple web site with static content, HTML, Js, Images, CSS & videos (totally could me max 3-5MB the whole content if the users visit all the site). The traffic of my web site will be 98% from UK and I am planning to have a maximum of 500.000 unique visitors per day.
My question is about performance.
Would you recommend me enabling CDN on my webrole? Would I benefit from it? is there a benefit using CDN even if my traffic is coming "mainly" from UK? is CDN content cached on Internet providers (eg. BT) proxy?
Would you recommend me hosting images, video etc on a blob storage account and reference it with absolute url from the web role? is there any difference in term of performance between hosting a static file on a blob (may be enabling CDN on the storage account?) or just put the static file on the web role?
I have not found many references online, but I guess that the web role, the CDN and the Storage, use different disks / cache layers / network layers and it should affect on performances.
