Earlier this month, Cecil Dijoux, a friend of mine posted a serie of four articles about high availability architectures on Tech IT Easy.

Through these articles, he covered the very different aspects of these architectures such as availability, scalability and performances. A very interesting reading that covers the current technologies trends in that area.

I’ve been quite passionate about this field of computing for the last five years. Since the SaaS trend is really coming true — with all the great web apps we’ve seen so far — building a high availability architecture for you app is really where the challenge is today.

I also recommend reading Building Scalable Web Sites from Cal Henderson (Flickr) and Scalable Internet Architectures by Theo Schlossnagle.
