As if tracking down bugs in a complex application isn't hard enough, programmers now must worry about a newly emerging trap, one in which a program compiler simply eliminates chunks of code it doesn't understand, often without alerting the programmer of the missing functionality.
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.
