Take aways:

• Shards – protection in silos
• Single-tier architecture; No remote storage
•  Evernote's business model and cost structure. Evernote is notable for their pioneering of the freemium model, based on the idea from their CEO: The easiest way to get 1 million people paying is to get 1 billion people using. *Evernote is designed to become profitable at a 1% conversion rate.
