Architecting Cloud Computing Solutions

Multi-data center architecture

Redundant single site designs can often handle many of the more prevalent issues that cause downtime within infrastructure layers. What happens if the entire site is not reachable? What happens if something gets misconfigured in DNS that sends traffic the wrong direction? The single site is now unreachable. Traditionally, the answer to this challenge has been very expensive. The redundant single site design nearly doubled the cost of infrastructure. For geographic redundancy, a second site is needed. This second site effectively doubles the budget of the first site, which already doubled when redundancy was added to the first design.

Cloud solutions are dramatically changing the way we design redundancy, resiliency, ...
