Yellow-Bricks Lately I have been thinking about what it would take to deploy a stretched vCloud Director (vCD) infrastructure. “The problem” with a vCloud Director infrastructure is that there are so many moving components, this makes it difficult to figure out how to protect each component. Let me point out that I do not have all the definitive answers to this yet, I am writing this article to get a better understanding of the problem myself. If you do not agree with my reasoning please feel free to comment, as I need YOUR help defining the recommended practices around vCD on a stretched infrastructure.

A ( ) is a "completely isolated guest operating system installation within a normal host operating system". [ 1 ] Modern virtual machines are implemented with either software emulation or hardware virtualization . In most cases, both are implemented together. [ edit ] VM Definitions A virtual machine (VM) is a software implementation of a machine (i.e. a computer) that executes programs like a physical machine. Virtual machines are separated into two major categories, based on their use and degree of correspondence to any real machine. Virtual machine
ARAnyM is a software virtual machine (similar to VirtualBox or Bochs) designed and developed for running 32-bit Atari ST/TT/Falcon operating systems (TOS, FreeMiNT, MagiC and Linux-m68k) and TOS/GEM applications on any kind of hardware - be it an IBM clone (read it as "PC" :-), an Apple, an Unix server, a graphics workstation or even a portable computer. ARAnyM is not meant as an emulator of Atari Falcon (even though it has a rather high Falcon software compatibility and includes most of Falcon custom chips including VIDEL and DSP). ARAnyM is better in the sense that it's not tied to specification of an existing Atari machine so we were free to select the most complete CPU (68040 with MMU) and FPU (68882), add loads of RAM (up to 4 GB), host accelerated graphics (even with OpenGL) and direct access to various host resources including sound, disk drives, optical storage devices (CD/DVD-ROMs), parallel port and more.
