Reshaping the world of servers and storage, network virtualisation is helping to make businesses more agile, more secure, and more reliable.

How it works

A virtual network includes anything that replicates your organisation’s physical networking equipment as software. This could include firewalls, switching, and routing.

To understand how virtualisation works in practice, assume that it takes ten servers to fulfil your company’s needs. Running each server on a separate computer would mean you’d need a total of ten computers, and a room with decent cooling to store them in. However, with virtualisation, your physical devices only need to forward packets of data, while the software takes care of the network’s intelligence. So, instead of ten servers, you’d only need a single off-the-shelf hardware platform. As a result, it’s easier to deploy and manage a virtual network, and scale up or down as needed.

A virtual network offers businesses the following benefits:

  • Increased scalability. Physical networks are usually only able to handle specific volumes of traffic. This can cause severe outages when these limits are exceeded. Scalability is one of the most attractive aspects of virtual networks, especially for growing businesses. Indeed, virtual networks offer on-demand expansion that matches your company’s needs.
  • Ease of setup and maintenance. Physical networks are hard to implement and can be problematic when technical failures occur. On the other hand, virtual networks can be set up in a matter of minutes And, being software-built, they allow for remote troubleshooting and maintenance – from a single cloud-based dashboard – saving your business valuable resource.
  • Reduced costs. Cost is a compelling argument in favour of virtual networks. With no upfront or infrastructure investment you simply pay for what you use, and how you use it.
  • Improved efficiency. Virtualisation can help you to reduce complexity through automation. In fact, with Cisco Digital Network Architecture, you can make network operations 28% more efficient using automation to manage policy and change at scale.
  • Innovate faster. With real-time network insights you’ll benefit from more informed decision making that could lead to actionable improvements.

A network as agile as your business needs to be

More than a trend, remote and mobile work are now part of life. And, a steadily growing number of companies are encouraging their employees to work outside of the office, as well as outside the traditional 9-5 routine. However, while delivering a boost in productivity, mobile working also comes with the challenge of ensuring that all data exchanges are secure and compliant. By segmenting traffic and guaranteeing a higher level of encryption, virtual networks are a powerful tool that can help your business embrace mobility in full safety.

Prepare for GDPR

Despite the UK’s decision to leave the EU, any UK company dealing with an EU organisation is still subject to the General Data Protection Regulation (GDPR). In response, it is vital that businesses make sure their sensitive data is encrypted. Not least because breaches could incur a maximum penalty of €20 million or 4% of worldwide turnover (and severely compromise your reputation).

Augmented data encryption is a significant benefit of virtual networks, and, with all UK businesses required to become GDPR compliant by 25th May 2018, is one of the main reasons why companies are now looking to virtualise their networks.

Get ready for the digital revolution

In the face of the IoT, modern businesses must adopt new digital strategies to simplify processes and transform their operations. And to do this, they need a network that can advance this digital transformation. A crucial step towards this, it’s no wonder that virtual networks are becoming more and more established.
