Instead of purchasing physical items, consumers today increasingly lease, stream, and rent products and services that support and bring value to their lives. Why? Because it helps serve their needs today, while allowing for a change in preference tomorrow.<\/p>\n
This need for flexibility spills over into the world of business IT. It\u2019s challenging to plan for the unknown when rigid hardware architectures limit the ability to react and adjust to changing business conditions. That\u2019s why revolutionary enterprise solutions like edge computing, cloud, virtualization, and containers are starting to be powered by software-defined technologies. IT organizations are shying away from hardware commitments and looking for innovations that give them the flexibility to deliver products and services today, while simultaneously adjusting and planning for tomorrow.<\/p>\n
Smartening up with software<\/strong><\/p>\n The move towards a software-defined infrastructure is about abstracting the control plane from the underlying hardware. When the brains of the system are separated from the brawn, the options for underlying hardware increase, becoming less expensive and more interchangeable, while the overarching software becomes more capable and faster, evolving as it adapts to the changing environment.<\/p>\n Enterprises that build on-premises clouds with software-defined infrastructures have three basic requirements: Friction-free agility of physical resources, control systems that maximize physical resource use and provide maximum return on investment, and an integrated infrastructure for automated provisioning and resource management.<\/p>\n While all of these requirements exist across the spectrum of the enterprise infrastructure \u2014 compute, storage, and network \u2014 the network plays a foundational role because it acts as the glue between compute and storage. That means the agility, control, and integrality of the network (or lack thereof) directly impacts a company\u2019s ability to deliver optimized applications. If the network is continually getting in the way, the business loses its agility.<\/p>\n The case for software-defined networking<\/strong><\/p>\n According to advisory firm Nemertes Research, more than 30% of organizations have software-defined technologies in place today. The main driver behind that trend is the need to automate and reduce the amount of time required to run the infrastructure. Examples of these cloud-driven IT consumption models include IT-as-a-Service in public cloud and private cloud scenarios.<\/p>\n Software-defined networking can best be described as giving enterprise IT the ability to manage data traffic from a central console instead of having to shape each individual switch manually. In a traditional network, switches send data in the same direction and in the same exact manner, but with software-defined networking, traffic can move in any direction. That flexibility allows IT to update switch rules to optimize performance and adjust to new priorities and requirements.<\/p>\n By using software-defined networking technologies, enterprise IT can solve traditional networking challenges such as latency, performance bottlenecks, and geographical boundaries\u2014resulting in a more responsive network strategy. In addition, they can adjust for future-looking requirements such as scalability and automation.<\/p>\n As companies continue to progress and move closer to an improved digitized state, they seek improved business agility by being smarter about compute, storage, and networking choices. The move from traditional \u201cbrawny\u201d data centers to software-defined technologies is a critical way to save on time and resources with businesses gaining flexibility to update services based on tomorrow\u2019s preferences.<\/p>\n
