Virtual servers still face real security threats

Don't let the word "virtual" in virtual servers fool you. You're the only one who knows it's virtual. From the perspective of the virtual server itself, the devices connected to it, applications running on it, end-users connecting to it, or security threats trying to compromise it, the server is very, very real. A new survey from Kaspersky Labs found that many IT professionals understand that securing virtual environments is important, but don't fully understand the threats or how to properly defend against them.

First look: Docker is a better way to deploy your apps

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.
