OPENSTACK THAT JUST WORKS

Tapjoy has hundreds of millions of active users.

They process billions of requests per day.

They were doing much of that in AWS, until they realized they could increase their

capacity

500%without spending an extra penny--by building

a private cloud

Why AWS?

Amazon Compute Units are meant to be ambiguous.

When VM prices go down, Amazon margins go up.

Would you rather pay $1.4 million over three years, or $3.2 million?

Amazon equivalent
