Amazon Web Services (AWS) is Amazon's cloud platform, offering infrastructure and platform services on demand. Its portfolio includes compute, storage, databases, networking, analytics, security and identity, developer tools, artificial intelligence and customer-contact applications. Customers range from start-ups and large enterprises to government agencies. The services are used through a web console and APIs and can be combined with on-premises, hybrid or edge setups. AWS is not open source.
AWS is a subsidiary of the US company Amazon. Services run in multiple regions worldwide, including Europe, so customers can choose where their data is stored. In January 2026 AWS also launched the AWS European Sovereign Cloud, a separate environment within the EU, with a first region in Brandenburg, Germany. According to AWS, it is operated by EU-resident staff and German subsidiaries. The parent company remains American, so you should assess whether US legislation such as the CLOUD Act is relevant to your data.
