[BNM] UML or V-Server on EC2
Jay Caines-Gooby
stable EC2 architecture and are getting a feel for what works and what
doesn't, I'm looking at what else we can do with it.
The most immediate issue is that we have a single nginx server
proxying both mongrel and fast-cgi. Stopping nginx means *everything*
stops however briefly. I'd like a bit of separation here. Because EC2
uses Xen, we can't use another system-level virtualisation technology
(no Xen-on-Xen and "its turtles all the way down" action possible) but
anecdotally, it seems that UML or Linux V-Server OS virtualisation
seems to be do-able with little performance penalty.
What's V-Server like to administer? Can the host OS continue with its
own functionality, or is it all given over to running V-Server virtual
instances?
Ideally, I'd like to add a basic virtual host which just runs its own
nginx and fastcgi servers, and keep the rest of the existing server's
functionality without having to V-Server this as well. We could buy an
additional elastic IP for it, so it gets its own separate IP address.

This is an operating system level virtualisation similar to Jails in BSD

I have a fat kitten. When I temporarily stun it, I want a bit of it to
keep on purring. What technologies can I use to cut my fat kitten in
half?

The advantage you have over linux here is that you've got DTrace & ZFS.
DTrace probes for mysql are in the pipeline, this will allow you to
analyse what mysql is doing in realtime (queries etc) which should make
troubleshooting & finding bottlenecks much easier.

No worries,
Looks like they've built DTrace probe for RoR aswell which will allow
you see what's going on with your code in realtime aswell!
"DTrace probes have been integrated into the Ruby source code, and this
provides low overhead monitoring for your Rails application."
