Over the past few years, the cloud and virtualization have been big topics among enterprise IT teams. The cloud offers an ideal way for enterprises to access and consume data and applications. However, its not enough for businesses to simply embrace cloud and virtualization.

To get the most from the cloud environment, an in-depth look at the entire network infrastructure is needed. Limitations in overall agility and responsiveness in the network infrastructure can have a drastic effect on an applications quality of service as its delivered over the network.

The Need for a More Dynamic Network

Network virtualization is one of the driving forces behind creating a dynamic cloud environment. As network performance improves, so does that of the cloud environment itself. However, many businesses are dealing with the cloud as it is today — bogged down by a mismatch between the data center networks operational agility and its ability to deliver applications in a timely manner.

Meanwhile, server virtualization has helped businesses better manage their computing resources. Servers that were once devoted to a single application now handle dozens of virtual machines, with each available at a moments notice. The resulting explosion in virtual endpoints has had a direct impact on network infrastructure.

Networkinstantiationremains focused on the configuration-driven networking model. This static and highly manual approach will soon give way to dynamic network serviceauto-instantiation, providing users with improved operational efficiency.

SDNPlays a Transformative Role

The latest trend for cloud-based enterprises involves incorporating software-defined networking (SDN) into the larger cloud infrastructure, creating an open, programmable asset that paves the way for network virtualization. It also gives businesses greater control over their network, resulting in reduced operational and capital costs.

Simplifying the network through abstraction is just one way thatSDNprovides a more responsive playing field for application deployment. Instead of relying on outdated network implementation details, enterprise IT teams can focus on fostering an IT-friendly approach towards designing and implementing network services that best serve application needs.

Policy-based automation is another key benefit ofSDN. By adopting a policy-basedauto-instantiationmodel, businesses can move away from the configuration-driven approach of old and embrace a simpler and more efficient approach that does away with burdensome layers of operational complexity.

SDNholds the key for cloud services to live up to their full potential. Byvirtualizingthe network infrastructure and making it as dynamic as possible, businesses can enjoy a greater level of agility and operational simplification from their cloud environments.
