AWS failures have caused multiple digital clearing exchanges to trade or restate business anomalies. August 23, 2019 (there is no special description of Beijing time below), Binance issued a notice saying that because of the network service provider (AWS, Amazon Web Services, Amazon cloud computing service, is a cloud computing platform created by Amazon) In some computer room failures, Binance's recharge and withdrawal functions were suspended during the period from 13:30 to 19:50 on August 23, 2019, Hong Kong time.

Multiple redundant cooling systems fail in a partial area of ​​the affected Availability Zone. The freezer resumed at 14:21 on August 23, and by 17:30, most of the anomalies had recovered.

AWS currently offers more than 165 services. AWS was launched in July 2002 and offers many remote web services. In 2019, AWS provided more than 165 services including computing, storage, database, networking, analytics, machine learning and artificial intelligence (AI), Internet of Things (IoT), security and application development, deployment and management. The most popular services include Amazon Elastic ComputeCloud (EC2) and Amazon Simple Storage Service (Amazon S3). EC2 allows users to have virtual computer clusters that are readily available over the Internet.

AWS currently operates 69 Availability Zones (a fully isolated partition of AWS's global infrastructure) in 22 geographic regions around the world, and plans to add three regions, Cape Town, Jakarta and Milan, while adding nine more Availability Zones.

The AWS global cloud server market ranks first. In 2010, AWS estimated revenues to be only $1.5 billion. By the end of 2018, AWS annual revenue had grown to $25.62 billion. According to Gartner, AWS ranks first in the global cloud server market, accounting for 51.8% of the global market. AWS has a broad customer base around the world, and the official website says AWS has millions of active customers and tens of thousands of partners worldwide.

However, there have been many major failures in AWS history.
