AWS has detailed how its cloud-computing infrastructure supported Amazon's huge Prime Day sales event.

Amazon's Prime Day 2022 on July 12 was its biggest since kicking off the event in 2015. This year, Prime subscribers bought more than 300 million items worldwide during the event. Customers were purchasing items at a rate of 100,000 per minute worldwide, and at 60,000 a minute in the US,according to Amazon .

Amazon Aurora is Amazon's MySQL and PostgreSQL-compatible database. On Prime Day 2022, 5,326 Aurora instances processed 288 billion transactions, stored 1,849 terabytes of data, and transferred 749 terabytes of data. 

Amazon increased the total number of "normalized instances" (an internal metric) on Amazon Elastic Compute Cloud (EC2) by 12% in 2022 compared to Prime Day 2021. 

This year for Prime Day it also added 152 petabytes (1 petabyte equals 1 million gigabytes) of Amazon Elastic Block Storage (EBS), which handled 11.4 trillion requests per day and transferred 532 petabytes of data per day.  But Amazon notes it used about 4% less EBS storage and transferred 13% less data than it did during Prime Day 2021.

Amazon's Simple Email Service peaked at 33,000 Prime Day email messages per second while itsSimple Queue Service (SQS) peaked at 70.5 million messages per second, setting a record for it. 

Amazon Alexa and the amazon.com sites are underpinned by DynamoDB. The sites made trillions of calls to DynamoDB application protocol interface on Prime Day. The database peaked at 105.2 million requests per second. 

The Amazon Robotics Pick Time Estimator uses Amazon SageMaker to train a machine-learning model to predict how long future pick operations will take. It processed more than 100 million transactions on Prime Day. 

Finally, AWS offered some metrics about its package-planning systems for delivering Prime Day purchases. 

On Prime 2022 day in North America, its package-planning systems performed 60 million AWS Lambda invocations, processed 17 terabytes of compressed data in [S3], stored 64 million items across Amazon DynamoDB and Amazon ElastiCache, served 200 million events overAmazon Kinesis , and handled 50 million Amazon Simple Queue Service events.  

These are no doubt impressive figures for one of the biggest online-shopping events each year. But Amazon is not immune to the macro-economic pressures of inflation, causing price rises in food, vehicles, computing components and streaming services. 

Amazon today told Prime customers in Europe that it is raising Prime fees by as much as 43% for the delivery and streaming service.

European Prime subscribers will see the price rise on subscriptions that are renewed from September 15.

The price rises affect Prime subscribers in the UK, France, Germany, Italy and Spain. Brits will see annual subscription prices rise by 20% from
