After hearing pagers going off throughout that day, it's reassuring to hear someone on the outside say everything went flawlessly.

I’m curious, how do you prep for things like the Prime Day? I imagine almost all parts of Amazon.com and AWS operate at their limits, especially resource-wise. What precautions do you take?

You might be interested to read the white paper that was linked in TFA.

Just do an internet search for "prime day scam", or something to that effect. The FTC has been investigating Amazon for their price deception tactics: https://www.reuters.com/article/us-whole-foods-m-a-amazon-ft... Here's more on the report: http://www.consumerwatchdog.org/story/your-amazon-sale-item-...

I'm not going to say you're lying but I think you're being eh misleading. This investigation is happening due to increased scrutiny of the Whole Foods merger and isn't a formal investigation by the FTC. Effectively the FTC is required to do its due diligence and the FTC has not accused Amazon of anything. It's some third-party group making the accusation.

> A study conducted by Consumer Watchdog in March found that for 61% of Amazon AMZN, -2.48% products, the pre-discounted price or “reference price” used for comparison with the new sale price was higher than what the products had been sold for in the past 90 days. This means the amount Amazon advertises under “you save” could be inaccurate. Amazon said the prices reflect averages of prices listed by competitors and other sources.

What is Dynamodb used for internally? Looks like it's being used for fulfillment and checkout as well. Is Amazon entirely based out of Dynamodb nosql ?

According to this Amazon job listing [1], DynamoDB isn't even the biggest (in terms of throughput) data store that Amazon uses. [1] https://www.amazon.jobs/en/jobs/447605/systems-engineer

I miss SABLE. I like it better than DDB, but I'm probably in the minority there. It made building high throughput services easy. I'm somewhat surprised it mentioned publicly.

This is a good example of the stupidity of the normal rules that Hacker News enforces about article titles. I am glad they made an exception in this case. I never would have read this if the headline text had been "Prime Day 2017 – Powered by AWS". I did read the article, because in this case, Hacker News allowed the title to highlight what I would find interesting: the incredible performance of DynamoDB.
