- Amazon’s Prime Day is a major event for the ecommerce giant, and for its customers who swarm to the site for deals.
- But it’s a test extraordinaire for the company’s tech teams, including Amazon Web Services, the cloud giant that provides much of the tech that the shopping site uses. (Amazon is one of AWS’s biggest customers).
- The AWS teams spend months preparing for it, Amazon says.
- On Friday, AWS released some mind-boggling statistics of the kind of technical firepower AWS deployed to make Amazon’s biggest shopping event happen.

Every year, the teams at Amazon Web Services spend months preparing for their sister company’s biggest event of the year: Prime Day. It’s a major test for the company’s tech teams, especially Amazon Web Services, the cloud infrastructure service that provides much of the tech that underpins the shopping site. (Amazon is one of AWS’s biggest customers).
2019 was such a big Prime Day it lasted for two days and although a handful of customers reported some technical glitches, it was mostly smooth sailing. That was a nice change from the 2018 Prime Day, when so many people overwhelmed the site that it famously crashed. That episode caused Amazon’s competitors to troll Amazon pretty mercilessly in 2019, with eBay announcing a "crash sale" and online betting site Bovada letting gamblers wager on the odds of a crash.
To support that level of frenzied buying, AWS’s Jeff Barr rattled off some stats on what went on behind-the-scenes. Barr is AWS’s prolific evangelist blogger who has become so famous in the AWS world, there are cartoon stickers of available of him for developers who like to decorate their laptops with such things.
Here’s a few stats he shared:
The Amazon Dynamo database is used by Alexa and all 442 Amazon warehouse fulfillment centers.
- It fielded 7.11 trillion calls to the Dynamo API
- At one point, it was handling 45.4 million requests per second.
(An API is a service that links the database to other applications.)
Amazon’s other database, Aurora, is also used by the warehouse fulfillment centers. It’s stats for Prime Day are also mind boggling:
- 1,900 database instances (aka, the number of databases that were running)
- 148 billion transactions processed
- 609 terabytes of data stored, and
- 306 terabytes of data transferred.
Prime Day also used AWS compute services which amounted to
- the equivalent of 372,000 servers at the start of the day
- and scaled up to 426,000 server equivalents at peak.
As for storage, the event used a high-performance service called Amazon Elastic Block Store.
The AWS team added an additional 63 petabytes of storage for Amazon ahead of Prime Day. A petabyte is 1 million gigabytes. All told, this storage system fielded:
- 2.1 trillion requests per day
- and transferred 185 petabytes of data per day.
- Google Cloud has changed how it pays its salespeople, ripping a page out of the Oracle playbook
- Despite the looming threat of Amazon’s cloud, some software companies are going all in on free software. Others are fighting back.
- To prevent disasters like the Capital One hack from happening again, experts say Amazon Web Services could do more to protect customers from themselves
