Network pain affects every IT manager.
- Network hardware like load balancers are expensive.
- Network design is complex, especially sprawling enterprise networks and multi-tenant ISP networks.
- Expertise is required to keep them running.
Any company that can ease this pain is onto a good thing. Virtualizing network technology is a hot cloud topic that companies like Embrane, Nicira and Big Switch Networks are in the middle of. The next piece of virtual networking technology for me to deal with is a load balancer. Here, I talk about load balancing in general, and later I will use the AWS console to add a virtual load balancer to my new pair of Drupal instances.
