Arthur de Haan, responsabile dei Test e del System Engineering di Windows Live, fa una breve panoramica dell'architettura di Hotmail basata su SQL Server 2008.

Alcuni punti chiave:

  • We host well over 1.3 billion inboxes;
  • Over 350 million people are actively using Hotmail on a monthly basis;
  • We handle over 3 billion messages a day and filter out over 1 billion spam messages;
  • We are growing storage at over 2 petabytes a month;
  • We currently have over 155 petabytes of storage deployed (70% of storage is taken up with attachments, typically photos).
