Cool... Though the real key is that the mainframe is designed for something at or beyond five 9s (99.999%) uptime.
[HUMOR] Heard from a Tandem guy: "Your application, as critical as it is, is on a nine 5s (55.5555555%) platform." [/HUMOR] While other server farms (and I've worked with the USF architecture until caught in the undertow of the May 2007 RIFtide) have a slight advantage of cyberdiversity (with a mix of architectures) and an implicit ease of georesilience, you just need to set up mainframes in other places (though load balancers and DNS servers with short TTL zone files might not reside within the mainframe). The only real downside to having a single stegosaurus with a huge number of penguins on its back is the implicit "single target" for physical sabotage; A sea of servers may have something salvageable should a tank fire an armor piercing round at the server itself. :-) :-) :-) :-) -soup On Tue, May 23, 2017 at 2:08 PM, Dave Jones <djo...@itconline.com> wrote: > An interesting article from our friends at SUSE.... > https://dzone.com/articles/the-mainframe-versus-the- > server-farm-a-comparison > > Enjoy. > DJ > > -- > ITC-email-sig > > *David Jones **|**Managing Director for zSystems Services **|**z/VM, > Linux, and Cloud > 703.237.7370 (Office) **|**281.578.7544 (Cell)* > > *Information Technology Company <http://www.itconline.com/>* > > ---------------------------------------------------------------------- > For LINUX-390 subscribe / signoff / archive access instructions, > send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or > visit > http://www.marist.edu/htbin/wlvindex?LINUX-390 > ---------------------------------------------------------------------- > For more information on Linux on System z, visit > http://wiki.linuxvm.org/ > -- John R.
