This is pretty amazing. Navigating the EC2 pricing documentation is such a hassle. I tend to think of costs in terms of monthly, as well, and this is valuable when working out cost-proposal estimates for projects I'm pitching to potential clients.

It is missing is storage and bandwidth costs, which can be a nontrivial chunk of an EC2 bill.

And yes, it is hair pullingly frustrating experience trying to figure out how much an EC2 instance is going to cost you using Amazon's tools.

Huh. Apparently, running Postgres on RDS is tad bit more expensive than MySQL. Why is that?

The RDS FAQ reveals this:

Q: Why is the pricing for each RDS database engine different?

The pricing for each database engine of RDS varies because our costs are different for each. These costs include many operational components in addition to software licensing. We will continue to work hard to reduce costs and pass on those savings to our customers.

My guess is that Postgresql required them to write much more internal tooling to "get right", and the costs reflect that.

Always see Amazon price reductions being promoted on HN, I didn't relise it's still so expensive, compared to my hetzner dedi.

Yes, it's not apples to apples at all, but AWS runs about 5x the cost without considering bandwidth. If you use a lot of transfer, even between AZs (same price as between regions!), it will dwarf the hardware costs. Compare e.g. the Skylake EX51-SSD at $63 USD / month amortized for one year vs R3 High-Memory Double Extra Large at $300/month 1-year no-upfront. Both have 8 hyperthreads, AWS has ECC memory (good) and hypervisor overhead (bad), Hetzner has a newer processor and higher clock speeds.

Depending on your needs, dedicated hardware can run a lot cheaper. You can over-provision by 4x and you're still saving money. There are a lot of other benefits to AWS though, it's a huge ecosystem, and it's much more flexible.

Can you elaborate a bit? Is it the cost calculator? (https://calculator.s3.amazonaws.com/index.html)

What do you find frustrating? What can we improve? Let us know!
