150 million requests per day is just under 2 requests a second... 100k users/shard is also hardly impressive even if you account for 2x or 3x replication. I hate to sound like a dick, but anyone who has dealt with large scale web apps would consider this a starting point, not worthy of a architecture presentation. EDIT: Ah ha. Having never used Evernote before, they didn't make it very clear that they are essentially trying to build a SAN. I assumed they were storing plain text notes like stickies.

Ummmmm...there are 86400 seconds in a day, so that's just under TWO THOUSAND requests a second...significantly more than what you mentioned.

  You are right. 2k requests per second is still not much.

    > 2k requests per second is still not much. That's a completely meaningless statement if you don't specify what the requests do, and the resources available to make it happen.
