Pricing, since it's not explicitly mentioned in the blog post:
You pay $600 per month for each custom SSL certificate associated with one
or more CloudFront distributions. This monthly fee is pro-rated by the hour.
For example, if you had your custom SSL certificate associated with at least
one CloudFront distribution for just 24 hours (i.e. 1 day) in the month of June,
your total charge for using the custom SSL certificate feature in June will be
(1 day / 30 days) * $600 = $20.
