Lambda MicroVMs adds x86, excluding the Hong Kong deployment Region
AWS announced the architecture option on November 11; x86 requires a supported base image from version 3 onward.
AWS announced x86 support for Lambda MicroVMs on November 11, 2026. Documentation requires a supported base image from version 3 onward and matching container images and binaries. Arm remains the default.
The option covers Regions offering MicroVMs except Hong Kong, Malaysia, Thailand and Spain. Deployment exclusions do not establish whether residents can use another Region.
Developers can evaluate existing x86 tools and AI-code execution environments, but compatibility and performance were not tested here. Compute, snapshot operations and storage, and data transfer incur usage charges; account-specific x86 rates were not verified. Isolation still requires least-privilege access, network controls and code review. This update establishes no new Chinese or Cantonese capability.
