Without adaptable infrastructure, an IT organization can’t keep pace with business needs. The future of infrastructure has at its foundation a software-driven, automated and intelligent network.
As technologists modernize their IT infrastructure, they face a host of obstacles, including legacy infrastructure, poor system integration and teams whose programming skills aren’t up to snuff.
Whether IT professionals need to deliver new applications or create a more efficient IT environment, outmoded IT gets in the way. By contrast, a modern infrastructure adapts, helping IT pros keep pace with business needs.
“If our infrastructure doesn’t keep up, our vision for where the world is going won’t be realized,” said Manoj Manoharan, director of product marketing for Ethernet services at Comcast Business, during a panel discussion on the future of networking at the Interop 2017 conference.
According to panel members, the network is at the center of a maelstrom of change taking place in enterprise data centers. The change is making its way through all levels of the stack, from infrastructure to applications.
“The network [is] in the middle of a huge disruption that’s happening in the data center,” said Ravi Amangati, vice president of engineering at Cisco Systems Inc., “when compute is being virtualized … applications are [using] a microservices-based approach, and … networking has to be at pace with all these trends.”
To create a modern and responsive infrastructure, IT teams have virtualized data center infrastructure, from servers to storage to networking. Combined with analytics, virtualization helps the network stand up to new demands.
As hardware becomes virtualized and programmable through software, IT teams need the skills to enable integration – and the hardware needs to be able to integrate. How IT professionals choose their tools and design their IT environments to be automated, virtualized, programmable, secure and scalable will surely be the difference between success and failure.
Security, in particular, has become a key concern. As new devices are introduced to the network, and as companies connect to branch offices, technology professionals need to secure the entire IT continuum, from the network periphery to the data that travels on the network to mobile devices and sensors connected via the Internet of Things. As these devices proliferate, the attack surface only widens, and companies need to develop a continuum of security processes that protect the perimeter, content that carries sensitive data, and the data in motion and at rest.
In this guide to the future of networking, we look at some of the key areas in which network modernization is taking place, including SD-WAN, which enables branch office connectivity, network intelligence and analytics, networking security, and more.
