Understanding Virtual Networks in the Cloud

Virtualization is running rampant throughout the IT world, making its way into Cloud design in an attempt to improve the infrastructure of the rapidly expanding Cloud network. The recent development of virtual networking for the cloud and its application by various web hosting companies, including Virtual Internet represents another step forward in IT, but it may not be readily apparent why it is so important.

 1. Availability

The term “cloud” computing derived from the idea that a cloud can be seen from a wide area. The virtual network solution places the network onto the vast cloud, meaning that if someone in the New York office is working with someone in the Seattle office, they can work as if on the same network.

 2. Greater Security

A virtual network helps to isolate the systems running through the provider’s servers and data centers. The difference is fundamentally the same as going from one computer running two applications to two computers running the instances separately. This effectively filters out unwanted traffic and allows Cloud networking to exist without extensive security work.

 3. Speed of Implementation

Cloud options in general have the power of being predefined services that a service provider extends to its clients. A company that wants to run a virtual network can enlist the help of such a company and have a functioning infrastructure upgrade within a relatively short period of time.

4. Improved Network Scaling

Even with wireless networks, as more users are added to a network, the higher the costs of infrastructure go. Virtual cloud networks can be easily scaled up to the size a company needs to run its business.

 5. Better performance and resilience

When a system is virtualized, it receives a dedicated amount of system resources from the host computer. Without the virtualization, applications running on the host effectively fight for resources. If this happens, one application may decide it needs more resources and slow down others. In a network setting, this can slow down communication and operations, so utilizing virtualization to ensure a certain amount of resources are allocated improves the overall performance of the system.

 The Virtual Cloud

As virtualization continues to take over the role of other electronic devices, we may soon see the days where simple devices with an Internet connection are all that are needed to function in the IT world. At the very least, virtualization is expanding on the capabilities of the Cloud in ways that deserve close watching in the near future.
