Network security, business agility and cost savings; these are all key priorities for companies globally, and a huge challenge for IT departments. In this guest post, Martin Casado, SVP and GM of VMware’s network and security business unit, discusses how network virtualization holds the key to help IT departments deliver against the high expectations coming from the wider business, and drive forward companies’ key priorities.
The story of Network Virtualization
Thanks to server and storage virtualization solutions, businesses have already been able to transform their data centers and reap significant operational and capital savings through automation, consolidation and hardware independence, and greater agility through on-demand and self-service approaches to provisioning. These solutions have also helped to reduce operational complexity and better align and scale application infrastructure with business priorities.
However, the full potential of these solutions remains to be achieved, and many businesses are being held back by antiquated network operations, which remain rigid, complex and proprietary, and closed to innovation. Networking services often still require manual provisioning and are anchored in vendor specific hardware and topology, which stands in stark contrast with the modern, easy to provision server and storage solutions.
The answer is network virtualization, which brings the operational model of a virtual machine to acustomer’s data center network, transforming the economics of network and security operations. This increases delivery speed and operational efficiency, reduces hardware dependency and lowers costs.
And it doesn’t stop there.
Micro-segmentation and Security
A key benefit to VMware’s network virtualization solution VMware NSX lies in micro-segmentation. We’re not just talking about micro-segmenting the various processes within an SDDC architecture, but also about the role it can play in keeping your data center safe.
It’s important to build secure firewalls for your data center to prevent threats from entering, but when the inevitable happens and threats do break through, they often have free reign to attack other machines inside the data center as well. Micro-segmentation allows you to set up a honeycomb-like pattern of firewalls within your data-center and instantly apply new rules to the different firewalls. This means you can effectively trap and isolate threats before they can spread wider throughout your data center and help decrease the damage done.
Use-case: Schuberg Philis
Though we’re already convinced of the huge value of software-defined networks, the proof of the pudding is in the eating, and Schuberg Philis, a business tech company with a focus on mission critical applications, has already tasted it for you.
After increasingly seeing its network as a barrier to increasing business agility, Schuberg Philis looked to VMware’s NSX platform. This helped the company accelerate application roll out from weeks to little more than 18 minutes, and ensure its customers have easy access to the flexibility of the cloud, but within a certified, auditable environment including built in controls and security.
The message is clear, network virtualization is the way forward.
