I just started using AWS yesterday and was pretty annoyed by the really counter-intuitive AWS website. I've been using other IAAS before, but AWS's information is all over the place.

Thanks a lot, really helpful for me atleast!

I still don’t understand this industry’s obsession with predefined fixed limits on unrelated resources.

Just because I want lots of RAM, why do I necessarily need lots of disk and/or lots of transfer?

Or vice versa, why do I need to pay for lots of tranfer and RAM to get lots of disk?

I get that AWS has separate billing for data, but they still tie CPU, RAM and Disk space together, as do most “traditional” VPS hosts.

And even more confusing to me, is why anyone with any sense would pay for these things?

1. It keeps their billing simpler. They would have to (or otherwise make it up elsewhere) charge different rates for different resources, making it relatively confusing + increasing support costs.

2. Much easier to forecast resources. If you know that you can fit X instances of type Y on a box, or W instances of type Z, it's easier to understand when/where you will need more hardware.

It's not perfect, I agree, but if an ad-hoc VPS product was profitable I'm sure we'd have seen it by now.

This isnt EC2 but I'd imagine they have the same limits with pricing vs hardware vs options

"Unfortunately given how physical resources are segmented if we gave users the ability to arbitrarily select CPU, RAM, or HDD independent of each other they would actually end up paying more for this 'custom' plan than using one of the pre-defined plans.

As I'm sure you are a well aware the resources are not equal and are not priced equally, it's cheaper to get more disk, than to get more RAM, which is why we've done our best to cut it up into units and provide the best cost savings to our customers."

Am I missing something or does this not include options for the reserved instances? Because _that_ is the part of the EC2 pricing that is most confusing to me.

Reserved instances are most likely for people not like us. You should be modeling your apps to take advantage of spot pricing not reserved.
