Canadian airline company WestJet is one of the earliest customers of VMware's NSX network virtualization tools, which initially reached for the tech to address a security issue. Network World Editor in Chief John Dix recently sat down with WestJet technologist Richard Sillito to learn what the company is learning about network virtualization and its broader NSX plans.
Most of the time, one operating system per computer is enough. But on occasion, you might want to boot up a second operating system for security reasons, testing purposes, or compatibility with specific software. Technical details typically restrict that alternate OS to a single PC, however. You can only install an OS in a single location after all.
Facilities solutions specialist ABM has more than 100,000 employees and customers around the world, all served by a small IT team struggling to deliver IT services to its constituents. It needed to find a way to deliver IT services faster and cheaper and says virtualization with Hyper-V is the way forward.
Trying to protect your expanding virtual machine (VM) empire will require a security product that can enforce policies, prevent VMs from being terminated or infected, and deliver the virtual equivalents of firewalls, IPS and anti-virus solutions.
A long time ago, a computer program was a stack of punch cards, and moving the program from computer to computer was easy as long as you didn't drop the box. Every command, instruction, and subroutine was in one big, fat deck. Editors, compilers, and code repositories have liberated us from punch cards, but somehow deploying software has grown more complicated. Moving a program from the coding geniuses to the production team is fraught with errors, glitches, and hassles. There's always some misconfiguration, and it's never as simple as carrying that deck down the hall.
After years of false starts, virtual desktop infrastructure (VDI) products are here. They work, and if implemented correctly they can deliver substantial cost savings to enterprise IT shops. What are the risks and rewards involved in embarking on a VDI implementation for your organization?
VMware's latest salvo in its virtualization war with Microsoft is vSphere 5.5, which features a host of improvements, the most interesting being high availability, support for Big Data/Hadoop and improved storage and backup.
The proliferation of virtualization coupled with the increasing power of industry-standard servers and the availability of cloud computing has led to a significant uptick in the number of servers that need to be managed within and without an organization. Where we once made do with racks of physical servers that we could access in the data center down the hall, we now have to manage many more servers that could be spread all over the globe.
At first blush, F5 Networks' new Synthesis Architecture for Software-Defined Application Services might appear to compete with new offerings from Cisco and VMware. But no, F5 CEO John McAdam and executive vice president of Strategic Solutions Manuel Rivelo tell IDG Communications Chief Content Officer John Gallant that F5 is very much in sync with these two data center giants (we did not, however, press them on the relationship between Cisco and VMware).
