Virtualization software invaded the IT market in 2005, conquering territory much faster than anyone imagined as running multiple virtual machines side by side on the same hardware offers considerable advantages.
Operational expenses and capital costs can be cut dramatically. An IT infrastructure with a stronger focus on software rather than hardware provides more flexibility, control over data and automation opportunities. Other benefits entail the ability to recover quickly from systems failures, securing business continuity and the possibility to test and develop applications in a secure environment without impact on the main IT systems.
But virtual environments do not only have the same challenges as physical ones -needing protection from external threats- but also those unique to virtualization. Virtualization can create gaps in visibility, including inter-Virtual Machine (VM) traffic within a platform hosting multiple VMs.
With orchestration and automation on the rise Virtual Gateway technology has shifted to a higher gear. Enabling the Software-defined datacenter to enforce security protection in the most flexible way. Fine-grained policies tied to NSX security groups and vCenter VM objects, adjust dynamically to network changes. This simplification and acceleration in application and service delivery will often provide the necessary futureproof visibility into the internal network traffic.
Nowadays virtual gateway technology exists for
