Enforcing data residency with single-Region Claude Code on Amazon Bedrock
TL;DR
A regulated customer needed all Claude Code inference processed in a single AWS Region (London), not just in-geography. This post shows two ways to pin Claude Code on Amazon Bedrock to one Region: an application inference profile or the Mantle endpoint, paired with an IAM Region condition, plus how to verify compliance in AWS CloudTrail.
Nauti's Take
Good news for teams under strict data rules: Claude Code now works in places where the region question alone used to be a blocker, with CloudTrail evidence to prove it. The catch is the cost of that narrowness, since a single Region means less fallback capacity during spikes and outages.
Banks, insurers and public agencies will find the setup worth it, smaller teams are better off with the default.
