Heroku needs to open source the testing (UPDATE: and data) it has used to claim 3X performance.

Adding a single graph for a $2000/mo DB, only performing read only transactions at 30% of its connection limit doesn't sound like putting the DB through its paces, and not real world.

It's great to see Matz investing time with the community whenever he is in town. And a nice bonus to have it streamed

I would replace 'super interesting' with 'Super complex'. It's an example of how you can make the price of a $10-40/mo server complex to the extent that you need to read the blog post numerous times before you understand the construct.

And even then, one still needs to factor in the 'other' costs like I/O or IOPs, disk (persistent/EBS), IPs, internet and inter-region data transfer… before you understand the real cost.

And then you need to compare to other instance types (which soon will cover the full alphabet -- c, cg, cr, g, h, i, m, r, t… ) and then other providers.

You still have several unresolved issue -

1. Are your assumption on usage (cpu, I/O, internet etc) correct? Will they change? 2. How do I compare performance across providers for a given VM specification. 3. Can I get support when I need it?

And I am sure there are others

It certainly means there is room for other players who just make it simple, whether they are infrastructure folk (like DO/Linode etc) or platform plays that make the pricing understandable by the audience they are trying to target (like Heroku/Ninefold)

Depends on your use case. Advantage is around performance, and that you don't have to focus on the devops part of deployments that Capistrano requires. You get full access to servers & free SSL for rails apps. Strong engineering support.

If you have a Rails App, you should consider Ninefold.com. You deploy direct from Github (or your Git Repo) and can have a VPS in the same security group if you need a utility box.

The embedded image in the article crystallizes everything. I wish I could repost it in the comments.
