Google and Geo-location, CNDs, DNS Load Balancing-Week 50

You can find this week’s video here.

This week answers two Q&A questions from viewers. DNS Load Balancing and then some discussion and a walkthrough using Application Request Routing (ARR) for a Content Delivery Network (CDN).

There’s a growing movement towards Content Delivery Networks (CDN); fronting web farms and geographically dispersing websites. This week I continue with Q&A’s from viewers, taking questions on DNS Load Balancing and CDNs.

Question 1:

I would love to see some clever DNS load balancing (not sure what capability windows is offering). Flesik

Question 2a:

I would love to see an end-2-end CDN redundant network setup (dns balancing, ARR nodes, parent notes etc). Flesik

Question 2b:

I would be interested in seeing a series on building an ecdn or ecn using ARR and what the best practices would be to scale it out geographically.

It seems ARR is sold that way... really not sold but talked about. I have tried to put my theory out and try it but i just don't know the best way to route my clients to their designated locations. Can you help out with an awesome weblog maybe? Adam

In this week’s video we look at DNS load balancing and geo-location issues that Google faces by using DNS to determine a user’s location. We also take a look at using Microsoft Application Request Routing (ARR) to create a CDN.
