AWS Lambda MicroVMs now supports the x86 CPU architecture
AWS Lambda MicroVMs now supports x86 CPU architecture, enabling direct execution of existing x86 applications without modification while maintaining VM-level isolation.
Amazon Web Services announced that AWS Lambda MicroVMs now supports the x86 CPU architecture, allowing users to run existing x86 applications, tools, and dependencies without recompiling or porting. This update enables developers to deploy workloads on Lambda MicroVMs using the x86 architecture, complementing the existing Arm (AWS Graviton) support. The feature provides isolated MicroVMs tailored to specific workload requirements, ensuring near-instant launch, resume capabilities, and state preservation.
Lambda MicroVMs serves as a serverless compute primitive designed for running user or AI-generated code in isolated environments. The service supports applications such as AI coding assistants, CI/CD runners, interactive development environments, and vulnerability scanners. With today’s launch, x86-based workloads can now be executed on Lambda MicroVMs without architectural changes, while Arm-based workloads continue to leverage AWS Graviton processors as the default option.
To utilize x86 workloads on Lambda MicroVMs, users can select the x86 architecture when creating a MicroVM image from a Dockerfile and launch MicroVMs from that image. The feature is accessible through multiple AWS interfaces, including the Lambda console, CloudFormation, Cloud Development Kit, or via the Agent Toolkit for AWS, providing flexibility in deployment methods.
Support for the x86 CPU architecture is available in all AWS Regions where Lambda MicroVMs is offered, excluding Asia Pacific (Hong Kong), Asia Pacific (Malaysia), Asia Pacific (Thailand), and Europe (Spain). Additional details are available in the AWS Lambda MicroVMs developer guide, with pricing information accessible through the Lambda MicroVMs pricing page.
