# Amazon Bedrock uses zero operator access and zero retention for inference

AWS keeps all European Bedrock traffic in one German region and adds an agent runtime version field.

Amazon Web Services says Bedrock uses a zero operator access data security model and a zero data retention model for inference, meaning no service operators can access model input or output, and prompts and responses are not stored by default.[^8]

All Bedrock inference requests, including those for Gemma 4, remain in the eusc-de-east-1 AWS Region in Brandenburg, Germany, within the AWS European Sovereign Cloud; global cross-Region inference is not available there.[^1]

For developers building agents, AWS SDK v3.1133.0 added a platformVersion field to the CreateAgentRuntime, UpdateAgentRuntime, and GetAgentRuntime operations of Bedrock AgentCore Runtime, allowing specification of the agent runtime platform version.[^5]
