RE: OT: Building Scalable Data Centers: BGP is the Better IGP

Petr,

The guy who bought Skype and Adconnect and thinks the MS Office suite "in the cloud" will keep the company relevant for the next 100 years should be fired and they should hire YOU as the CEO.

Also, they should let your manage and monitor the Azure Cloud's storage certificates, sorry about that outage from an EXPIRED CERT on the Azure cloud last week... (wonder if this is the "100,000 server datacenter" your draft refers to...

Great work man!

more info on design could be found here (only L3 aspects are covered, there is a LOT of important things at physical layer too):

http://tools.ietf.org/html/draft-lapukhov-bgp-routing-large-dc-03

Scale is irrelevant, main limiting factors would be application requirements, e.g. with regards to load-balancing. We do not implement mobility solutions that require L2 domain stretching, but it's possible to do this (though not recommended) over the L3 network.

Network management/config automation is integrated into AutoPilot

http://research.microsoft.com/apps/pubs/default.aspx?id=64604

Which is much more than configuration management system - rather an engine for complete data-center life-cycle management.
