AWS launches Lambda MicroVMs for isolated sandboxes
AWS announced Lambda MicroVMs, a new serverless compute primitive that provides a dedicated Firecracker virtual machine per user or session for fast-starting, stateful, isolated sandboxes. MicroVMs are created from Dockerfile-based images uploaded to S3, support persistent memory and disk state for up to 8 hours, offer automatic suspend/resume and vertical bursting (up to 4x baseline), and expose a dedicated HTTPS endpoint per MicroVM. The initial launch is ARM64 (Graviton) only and is available in several US, EU and APAC regions. Pricing is usage-based (vCPU-second and GB-second), with additional snapshot and image storage fees. AWS positions MicroVMs for use cases like coding assistants, AI-agent sandboxes, multi-tenant notebooks and vulnerability scanning where untrusted code must run with strong isolation and session persistence.
A major cloud provider (AWS) released a new managed compute primitive that changes how teams host isolated, stateful sandboxes and AI-agent workloads—impacting secure execution models, serverless architectures, and tooling for AI-driven developer platforms.

AWS EC2 vs Lambda: Pros and Cons
A short DEV Community post (Apr 23, 2026) by Ankush compares AWS EC2 and AWS Lambda across cost, flexibility, integration and development speed. The author notes EC2 uses a traditional instance rental model and offers greater flexibility, while Lambda charges based on invocations and memory consumed and represents a serverless, event-driven model. The post highlights that both options integrate easily with AWS services and mentions built-in capabilities such as load balancers, auto-scaling groups and target groups. The article is an opinionated technical comparison intended to help developers choose between managed server instances and serverless functions.
Cloud Run Sandboxes Enable Sub-Second Python in Google Apps Script
This developer article introduces a new architecture that connects Google Apps Script (GAS) with Google Cloud Run Sandboxes, which use gVisor micro-virtualization, to enable deterministic sub-second execution of Python and Bash scripts directly from Google Workspace. The solution overcomes GAS's standard limits (6-minute timeout, V8 JS only) by offloading compute to a Cloud Run Gen2 service that runs code in an isolated gVisor sandbox. The author provides an open-source implementation (GitHub repository) and documents an 8-axis test suite that verifies security properties like SSRF protection, environment variable isolation, read-only filesystem, and network egress blocking. Practical use cases include rendering Seaborn heatmaps from spreadsheet data directly into Google Sheets, with latencies of 200-450 ms. The article also compares this approach to Gemini Managed Agents, highlighting trade-offs in latency, cost, and persistence. The architecture leverages Google Cloud's free tier to minimize costs, with scale-to-zero when idle.
