After many attempts throughout the last 3 decades or so, it finally appears that Client / Server Virtualization is here to stay. Most people in the IT industry have heard of VDI, Virtual Machines, or Cloud Servers. One area of Virtualization Services that does not have quite as wide of an audience is the area of Network Virtualization.
Network Virtualization has been maturing quite a bit over the past few decades as well. From VLANs, or Virtual LANs that separate broadcast domains to provide a measure of isolation and manageability between hosts and servers, to VRFs (Virtualized Routing and Forwarding) that allow for separate Layer 3 routing and forwarding tables, as well as VPN (Virtual Private Network) services that are used extensively to allow clients and teleworkers secure and reliable access into the Enterprise, allowing the use of email, database, shared directory, and print service resources.
Network Virtualization can also include the segmentation of a single piece of infrastructure, such as a Cisco ASA Firewall, into separate distinct pieces or contexts. At FNTS, we are able to use Network Virtualization to provide our clients with a secure and completely functional ‘context’ of an ASA. This makes it possible to significantly lower the Total Cost of Ownership that is associated with buying another physical piece of hardware, and allows for a reduced cost to our clients.
This same type of device segmentation is used in our Network Load Balancing and Citrix Secure AG offerings. We are able to carve out cost effective, highly functional contexts that can serve multiple customers in a secure Fault Tolerant solution utilizing our Citrix Netscaler SDX platform, as well as our Cisco ACE platform.
Client / Server and Network virtualization throughout the data center has matured quite a bit over the years making TCO and ROI much more attractive for both Clients and Managed Service Providers alike.
