[Xen-users] Xen and EC2 power DARPA Network Challenge Team DeciNena
I just wanted to drop a note to this list and mention how awesome Xen (and
folk are into that) has been in helping me field my team website for the DARPA
Challenge (tomorrow) https://networkchallenge.darpa.mil/default.aspx
My site, Team DeciNena:
is currently run on a 32-bit Ubuntu PV DomU (LAMP+Drupal) on a Debian 5
(Lenny) 64-bit Dom0.
Here's a writeup about our Drupal side of things:
We are anticipating high traffic during the event tomorrow, so we have
site over to Amazon EC2/S3/RDS. We have one central RDS (EC2/Xen cloud system
MySQL) that runs the database, and we can dynamically add/remove nodes from teh
cluster via Amazon's AWS control panel.
We also have one EC2 machine running and NFS server that stores and shares
dynamic site content (static site content like the Drupal installation lives on
EC2 node to reduce NFS traffic).
We also have any number of identical EC2 Ubuntu nodes installed with Apache
Drupal site. These actually process the HTTP requests from the client users,
and talk to
the NFS and RDS servers.
The original Xen machine switches to being a load-balancing redirector when
makes the cutover to the cloud-based implementation, so I don't have to wait
changes to propagate.
Xen and Xen-based-EC2 have been instrumental in making this happen.
Yes, I'm also blatantly self-promoting my team. Come join me and maybe share
in part of
the $40,000 prize, even if you aren't the one who spots a balloon. Even if you
I request you send a note to your friends/twitter/facebook about it. That's the
goal of DARPA's game -- social network exploration.
