Today, I'm excited to share that, for the first time, the same machine learning courses used to train engineers at Amazon are now available to all developers through AWS. We've been using machine learning across Amazon for more than 20 years. With thousands of engineers focused on machine learning across the company, there are very few Amazon retail pages, products, fulfillment technologies, stores which haven't been improved through the use of machine learning in one way or another. Many AWS customers share this enthusiasm, and our mission has been to take machine learning from something which had previously been only available to the largest, most well-funded technology companies, and put it in the hands of every developer. Thanks to services such as Amazon SageMaker, Amazon Rekognition, Amazon Comprehend, Amazon Transcribe, Amazon Polly, Amazon Translate, and Amazon Lex, tens of thousands of developers are already on their way to building more intelligent applications through machine learning.
Amazon Macie is a security service that uses machine learning to automatically discover, classify, and protect sensitive data in AWS. Amazon Macie recognizes sensitive data such as personally identifiable information (PII) or intellectual property, and provides you with dashboards and alerts that give visibility into how this data is being accessed or moved. The fully managed service continuously monitors data access activity for anomalies, and generates detailed alerts when it detects risk of unauthorized access or inadvertent data leaks. Today, Amazon Macie is available to protect data stored in Amazon S3, with support for additional AWS data stores coming later this year.
Amazon has reported a surge in sales helped by a rise in US retail sales and demand for its cloud services. Sales in the three months to the end of June were $52.89bn (£40.3bn), up 39% on the same time last year. But the e-commerce giant warned investors that growth could slow in coming months. Despite the caution, the firm's shares jumped more than 2% in after-hours trade as investors responded to strong profit growth. Amazon said profits rose to $2.53bn in the three months to the end of June - more than 12 times last year's profit.
