Every boxer wants to float like a butterfly and sting like a bee. To have an awesome offence combined with a solid defense. Giving punches, but not taking any in return – which is a neat way of thinking about network virtualization:
Network virtualization is pretty well understood: using software to simulate the existence of expensive hardware.
However, running a number of virtual machines on a single physical computer system is about more than just cost. The benefits are similar to those associated with server virtualization:
So virtualization is about maximizing in-house servers. But it’s also about cost savings (hardware and energy), workload flexibility, and recoverability.
But to box smart is also to consider defense, or, in this case, security. In fact, it’s the ability of virtualization to offer more dynamic IT protection that’s brought many doubters around.
Virtualization allows for every virtual machine and every app (regardless of the device being used) to be isolated in its own secure space, thereby limiting the potential for ‘lateral infection’ – where malware moves sideways to contaminate one machine after the other.
All of which brings us to the heavyweight champion of network virtualization solutions: NSX from VMware. Its formidable reputation comes from the fact that it makes your underlying physical network abstract – thereby supporting a more agile and adaptive IT operation.
Yes, you’ll need hardware, but nothing more than a Layer 3 switch. However, it’s not limited to switching, as there’s a significant amount of network intelligence built into the software. That means you can design granular firewalling that’s optimized for east-west datacenter traffic, load balance the network, or create Layer 2 and 3 VPN services.
NSX is the ideal solution for getting you fighting fit, and for making security far more flexible than a traditional set-up. It can also grow autonomously, and support dynamic assignments versus workloads that can keep pace.
What’s more, with NSX you can dynamically assign security to workloads. The process is extremely simple: just start a new virtual machine, and watch as security is automatically added to the machine.
Third-party tools can take this automation further by instantly isolating any quarantined machine from the network (where the threat is removed before the machine is put back into service).
