What is software-defined networking (SDN)?
Software-defined networking (SDN) is an agile networking architecture designed to help organizations keep pace with the dynamic nature of today’s applications. It separates network management from the underlying network infrastructure, allowing administrators to dynamically adjust network-wide traffic flow to meet changing needs.
Software-defined networking seeks to reduce the complexity of statically defined networks, automate network functions, speed the deployment of applications and services, and simplify the provisioning and management of network resources.
What are the top benefits of software-defined networking?
There’s a reason IDC estimates that the worldwide data center SDN market will be worth more than $12 billion in 2022. Compared to the advancements in compute and storage virtualization, traditional networking has fallen behind in fully realizing the promise of enterprise cloud computing. The dynamic nature of cloud services requires a new level of flexibility and scalability, which goes beyond the capabilities of today’s data center networks.
Transitioning to software-defined networking (SDN) incorporates programmability and agility into your network, enabling it to keep pace with business demands.
A software-defined network allows you to:
- Support the dynamic movement, replication, and allocation of virtual resources
- Ease the administrative burden of the configuration and provisioning of functionality such as QoS and security
- More easily deploy and scale network functionality
- Perform traffic engineering with an end-to-end view of the network
- Better utilize network resources
- Reduce OPEX
- Have network functionality evolve more rapidly based on a software development lifecycle
- Enable applications to dynamically request services from the network
- Implement more effective security functionality
- Reduce complexity
