# Network File Storage Limits

Network File Storage is a fully managed, POSIX-compliant file storage solution built for demanding workloads like AI/ML pipelines, containerized applications, and DigitalOcean Kubernetes (DOKS) clusters. It provides scalable, high-throughput shared storage that simplifies storage management for distributed applications.
