Understanding Cloud Computing and vGW Series

A cloud is an Internet-based environment of virtualized computing resources including servers, software, and applications that can be accessed by individuals or businesses with Internet connectivity. Customers, referred to as tenants, can access the resources that they need to run their businesses.

Clouds possess the following advantages. They:

There are two kinds of clouds and a third one that combines the other two:

Cloud computing allows for dynamic and elastic generation of virtual infrastructure and virtual machines (VMs) with their own operating systems running over that infrastructure. Whether for public, private, or hybrid clouds, virtualized data centers must offer secure, discrete, VM environments to their customers and their organizations.

Physical network security is designed for and limited to physical hardware and its software. It does not have the visibility into traffic transmission and communication between VMs that is required to secure the environment. vGW Series secures the virtual network in ways that physical security mechanisms protecting physical networks cannot because it is purpose-built for virtualized environments. vGW Series provides support for IPv6 in addition to IPv4 to enable organizations that have adopted IPv6 to benefit from vGW Series cloud security.
