What a Virtual Cloud Network Can Do For Your Business
Everything of value today is connected to the network. And with IoT, 5G, AI, and other emerging technologies, connections will increase by orders of magnitude. Businesses that can provide secure connectivity—and harness the data their customers are generating in a secure, fast, reliable way—will win.
From Hardware to Software
Traditional enterprise networks were built by connecting physical devices—computers, servers, routers, and switches—to each other. Once a network was set up, security solutions were bolted-on at the end. Changes to the network were handled manually, leaving a wide margin for error and increasing the potential for costly outages.
The emergence of software-driven networks has challenged these existing norms. New technologies now allow for the abstraction of a network’s hardware, enabling software to run it more efficiently. Automation and programmability minimise a company’s operational complexity by replacing complicated manual tasks, enabling better scale and reliability. Today, with the advancement of software-defined networking, businesses that want to modernise their network with software open up a new set of possibilities to drive business innovation.
“With applications and data now residing everywhere, companies can no longer rely solely on a hardware-based network deployed inside their data centre to run their business,” says Rajiv Ramaswami, VMware COO for products and cloud services. “This new reality requires thinking of networking in a fundamentally different way.”
The majority of enterprises use, or plan to use, multiple clouds to run their business. Today, everything of value is connecting to the network and new customer experiences are delivered through the cloud. Users connect not only through their desktop and laptop computers, but also via mobile devices. Applications run everywhere across a company’s infrastructure; yet, many companies don’t have a clear understanding about the security and connectivity of their applications and devices across the data centre, branch, cloud, and edge.
These emerging technology trends increase the complexity of enterprise security and challenge the limitations of hardware-driven networks. Networking in software creates a business fabric that securely and consistently connects a company’s data centres, carrier networks, branches, endpoints, and clouds. And it’s all done independently of the underlying network hardware.
Better in Software
Virtual networks run more efficiently and lower operational costs by automating network infrastructure functions such as maintenance, patching, and updating. They also increase uptime, improve service, and reduce costs—enabling organizations to maximize the value of their existing network hardware while creating new innovation and business opportunities.
“Today, networking is less about connecting boxes and more focused on meeting the needs of applications,” says Ramaswami. “That means the ability to securely connect people to applications, and to connect each application to the resources it needs, regardless of where they are located.”
In addition to automating data centres, companies are turning to virtualized networks to improve security. With software, security policies can be set once and deployed across the network, following applications, services, and devices wherever they go. Technologies such as micro-segmentation, which enables security around individual workloads, provide additional protection.
“The amount of network traffic that moves east-west within the data centre has skyrocketed and with traditional security, it’s completely unprotected. Micro-segmentation addresses that,” says Ramaswami. “And with software-based networks, security is built into the platform so it can protect workloads running anywhere—whether they are running in the data centre, branch offices, in an AWS or Azure cloud, or even in modern app development frameworks such as Kubernetes.”
A Foundation for Innovation and Growth
VMware has a unique history of providing solutions that range across any device, application, or infrastructure. Only virtual cloud networking offers a complete networking vision from the data centre to the cloud and edge, all without the focus on the box.
Currently, around 10 percent of enterprise-generated data is created and processed outside a traditional centralised data centre or cloud. By 2022, Gartner predicts this figure will reach 50 percent1. According to IDC, 94 percent of enterprises are expected to embrace multi-cloud in 20182.
“Powerful new applications have become the lifeblood of companies across all industries,” says Ramaswami. “With the Virtual Cloud Network, VMware provides the tools to manage, secure, and connect those apps to users and data, wherever they may be, which is what companies are looking for to drive business forward.”
