In this 33rd quarterly recap post, discover the most impactful AWS serverless launches, features, and resources from Q2 2026 that you might have missed. Stay current with the latest serverless innovations that can improve your applications. In case you missed our last ICYMI, read about what happened in Q1 2026 . AWS Lambda MicroVMs is a new serverless compute primitive for running user or AI-generated code in isolated, stateful execution environments. Built on the same Firecracker virtualization that powers over 15 trillion monthly Lambda invocations, MicroVMs give you VM-level isolation with near-instant launch and resume.
Each MicroVM runs in its own Linux environment with no shared kernel or resources between sessions. This isolation makes it a useful solution for AI coding assistant sandboxes, interactive code or multi-tenant development environments, CI/CD build environments, data analytics platforms, vulnerability scanners, and game servers that run user-supplied scripts. Standard Lambda functions are best for event-driven, request-response workloads which have a 15-minute timeout. MicroVMs are purpose-built for single end user or session workloads and can preserve state for up to 8 hours. You get full lifecycle controls including launch, suspend, resume, and terminate.
You can suspend them during the 8 hours if you don’t need them active. MicroVMs retain memory and disk state for the length of the session, even while suspended. They can auto resume when you need to use them again. Serverless Land contains example applications and a resources page with more details.
