Amazon EKS (Elastic Kubernetes Service) is a managed Kubernetes service from Amazon Web Services. AWS operates the Kubernetes control plane, and with EKS Auto Mode it also manages the nodes. Clusters run in the AWS cloud, but through EKS Anywhere and EKS Hybrid Nodes they can also run in an organisation's own data centres. The service is certified Kubernetes-conformant, integrates with AWS IAM and offers managed capabilities for continuous deployment such as Argo CD. It is a cloud service with a console, API and CLI.
Amazon is headquartered in the United States, so the service falls under US jurisdiction, including the CLOUD Act. Customers choose the AWS Region themselves; European regions exist in France, Germany, Ireland, Italy, Spain and Sweden, as well as in Switzerland and the United Kingdom. AWS provides a data processing addendum that includes the EU Standard Contractual Clauses. Organisations that want to run Kubernetes without a US provider can operate open-source Kubernetes themselves or use a European provider.
