I'm wondering what are the growing trends in connecting Data Centers for
redundancy in DR/COOP environments. I imagine VPLS has a big play here, but
I'm willing to bet there are all sorts of weirdness that such environments can
create, such as the effect it may have on DR elections, etc.
We are doing:
Citrix XenServer environments at both sites with NetApps for the SANs
MPLS connections with Riverbeds for WAN op.
Let me know if you wanna dig into this deeper.

Roland,
Could you elaborate on GSLB (Global Load Balancing?) ? Pardon if
that question seems a bit noob-ish
Thanks

Layer-3-independence and active/active/etc. is where it's at in terms of
high availability in the 21st Century. GSLB, et. al.
Somewhere on video.google.com is a Google I/O talk explaining the hell that
is active/active redundancy and how hard it is to achieve at layers 4-7. I
don't argue that

Depends upon the type of apps, amount of required concurrency, etc.

Architectural choices, implementation scenarios, DNS tricks to ensure
optimal cleaving to and availability of distributed nodes within a
given tier:
Props for mentioning mod_backhand. Excellent tool for GSLB.

Also, commercial solutions from F5 (their GTM product and their old 3-DNS
product).
Using CDN's is also a way of handling this, but you need to be prepared for
all your traffic to come from their source-ip's or do creative things with
x-forwarded-for etc.
