Staff engineers at Modal detail a complete infrastructure overhaul designed to scale beyond Kubernetes limitations. The new architecture supports millions of concurrent sandboxes while sustaining creation rates of tens of thousands per second. This approach focuses on raw throughput and concurrency rather than traditional container orchestration patterns.

  • Modal replaced its Kubernetes-centric model to achieve massive concurrency scaling.
  • The system now handles tens of thousands of sandbox creations per second.
  • Infrastructure was rebuilt from scratch to support millions of concurrent instances.
  • Focus is on high-throughput serverless execution rather than standard pod management.

AWS Security Hub AI Inventory adds Azure self-hosted instance support

AWS Security Hub AI Inventory now discovers and catalogs AI assets on self-hosted Microsoft Azure instances. This update extends existing self-hosted discovery capabilities beyond AWS to provide a centralized view of AI assets and their security posture across multi-cloud environments. The service utilizes enhanced Amazon Inspector SBOM analysis to identify inference endpoints, models, and AI agents like Ollama, vLLM, and Hugging Face TGI on Azure virtual machines. Each found asset is mapped to its infrastructure and correlated with security findings for filtering.

  • Security Hub AI Inventory now supports Azure self-hosted instances for centralized AI asset discovery.
  • Amazon Inspector SBOM analysis identifies inference endpoints, models, and agents on Azure VMs.
  • Supports frameworks including Ollama, vLLM, and Hugging Face TGI.
  • Assets are mapped to infrastructure and correlated with security findings for filtering.
