Virtual Containerization
AlexGr alerts us to a piece by Jeff Gould up on Interop News. Quoting: "It's becoming increasingly clear that the most important use of virtualization is not to consolidate hardware boxes but to protect applications from the vagaries of the operating environments they run on. It's all about 'containerization,' to employ a really ugly but useful word. Until fairly recently this was anything but the consensus view. On the contrary, the idea that virtualization is mostly about consolidation has been conventional wisdom ever since IDC started touting VMware's roaring success as one of the reasons behind last year's slowdown in server hardware sales."
I've used virtualization for both containerisation and also to consolidate boxes too...
At my previous company, we invested in two almighty servers with absolutely stacks of RAM in a failover cluster. They ran 4-5 other servers for critical tasks...each virtual machine was stored on a shared RAID5 array. If anything critical happened to the real server, the virtual servers would be switched to the next real server and everything was back up again in seconds. The system was fully automated too, and frankly, it saved having to buy several not-so-meaty boxes while not losing much redundancy and giving very quick scalability (want one more virtual server? 5 minute job. want more performance? Upgrade redundant box and switch over virtual machines).
The system worked a treat, and frankly, the size & power of the bigger, more important fewer servers gave me a constant hard-on.
