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).
