Post-LLM validation. We're currently working on this at https://github.com/guardrails-ai/guardrails



Good advice!


I worked with Khawaja and Daniela at AWS. They always were strong advocates of developer experience and it really shows with Momento. Congrats on the launch!


Like the other comments mentioned your post misses of how transparent AWS has been in price reductions in the past.

More importantly, S3 now has several tiers of pricing depending on how frequently you access the data. So maybe lately they haven’t reduced the pricing of the top tier of S3 but they’ve made it significantly cheaper for other use cases of data. That is very contrary to the comments being made of innovators dilemma.

(I used to work at AWS but have no knowledge about pricing decisions)


if you're interesting in moving off Heroku to AWS without the complexity of Kubernetes, I would love to chat with you. safeer [at] tinystacks.com


This is very, very true. One of our customers described it really well “The nightmare of DevOps kept us from managing AWS directly, but with TinyStacks we can scale a billion+ requests a day in audio advertising leveraging the full power of AWS.”


What are you using for compute EKS and Fargate? We just helped someone switch from Heroku to AWS and they dropped their cloud costs by 67%. This is using ECS + EC2. Fargate is typically 2x more expensive.


Spot/Reserved instances are used.

I probably should have clarified that the extra cost was expected as we did a lot more in AWS than we could in Heroku, we used the switch to start using bunch of stuff AWS offers like Lambda functions, CloudFront, RDS etc. Stuff that we just didn't (and couldn't) use on Heroku, thus didn't pay for it.

As the purpose of the switch was to get more control, features and out of the Herokus "black box", higher costs were expected and perfectly normal.


Is that taking spot/reserved instances into account (for both). Afaik Fargate supports both of those


Without Spot/Reserved incentives. Could get even more if that’s done.


Really great post. When I was at AWS, we did everything with IaC but that luxury of time and investment is not avail to many. We're working on this problem but ensuring that devs has a) full transparency what's going on, b) ability to evolve their arch and c) building right on your AWS account. We just moved someone from Heroku to AWS handling 1B requests/day at 1/4 of the cost.

have a bunch of AWS execs backing us too; they know this is a problem. Happy to chat more if you want to give it a spin: tinystacks.com


cloud is a marketing scam. It is sold to execs as a magic black box that scales and you don't have to be concerned with how it works internally. In reality it's a set of leaky abstractions and you absolutely have to understand how black box works internally plus be aware of thousands of bizarre hard/soft limits and other gotchas.


OP here. If you're looking to move your Docker app to AWS, would love to help you with our one-click free tool: tinystacks.com. We can even migrate your database.
