I'd love to hear how Dynamo would end up being $2-3 million a year They sure do a great job of convincing people that it's cheap so I'm curious where the cost seems to blow up?

If you are doing north of a million ops on DynamoDB you can quickly run into the $2-3 million a year range. In this 2018 benchmark, we were able to calculate that a sustained, provisioned of only 160k write ops / 80k read ops for DynamoDB would cost >$500k per year: https://www.scylladb.com/2018/12/13/scylla-vs-amazon-dynamodb/ https://www.scylladb.com/2018/12/13/scylla-vs-amazon-dynamod... That was a few years ago. These days, according to our most current pricing you could do DynamoDB provisioned, 1 year reserved for $38,658/month, which is "only" $463,896 annually (pop up the "Details" button and choose "vs. DynamoDB"): https://www.scylladb.com/pricing/?writes=160000&reads=80000&storage=1&itemSize=1&replication=3#pricing-calc https://www.scylladb.com/pricing/?writes=160000&reads=80000&... The same workload on Scylla Cloud would be only $7,442/month, or $89,304 annually. If you wanted, say, 1m ops — 500k write / 500k read ops — on DynamoDB, that'll run you $131,078/month, or $1,572,936 per year. https://www.scylladb.com/pricing/?writes=500000&reads=500000&storage=1&itemSize=1&replication=3#pricing-calc https://www.scylladb.com/pricing/?writes=500000&reads=500000... The same workload on Scylla Cloud would run $29,768 reserved/month, or $357,216 per annum — 77% cheaper. Of course, all of this is just pure list price. Depending on volume you might be able to negotiate better pricing. However, you'd need a really steep discount for DynamoDB just to get back to Scylla Cloud's list price. Let me know if you spot any math errors or omissions on my part.

  Thanks for the response, Peter. I may shoot you an email with some additional questions.
