AWS adds x86 support to Lambda MicroVMs

Published Wednesday, November 11, 2026 · 2:21 PM EST

AWS has added x86 processor support to Lambda MicroVMs, allowing developers to run existing x86 applications and dependencies without recompiling or porting them. Developers can choose x86 or Arm when creating an image, giving each user or job an isolated virtual machine on the architecture its workload uses. The service runs user or AI-generated code for applications including coding assistants, development environments and vulnerability scanners. Developers create an image from a Dockerfile and launch MicroVMs from it. Arm remains the default architecture. The x86 option is available wherever Lambda MicroVMs operates except Asia Pacific (Hong Kong), Asia Pacific (Malaysia), Asia Pacific (Thailand), and Europe (Spain).
