The OpenStack Summit this week continued to fan the flames of the software-defined data center. The software-defined data center is just a term for replacing traditional data center hardware functionality with the same features implemented in software, running on commodity x86 servers. While software-defined approaches to data center features are at least nominally less expensive than their hardware counterparts the real promise in the approach is flexibility and management ease with high levels of integration. Reconfiguring a network to support the security requirements of a new application is now just a function of software and APIs. Expanding storage is just simply adding another node with more storage attached, and the cluster compensates automatically. Even things like firewall rules and load balancer configurations can now be stored as templates along with the applications, to be provisioned in minutes.
