Accelerate Next-Gen AI Workflows on Microsoft Azure with VAST
The VAST AI Operating System (VAST AI OS) on Azure consolidates your AI data into a unified global namespace, eliminating data copies, simplifying operations, and accelerating AI innovation. Each Azure deployment leverages storage-optimized virtual machines equipped with locally attached NVMe for high performance.

Data Silos Stall Your AI Projects
Most businesses have created storage silos along three axes: applications, data types, and geographic locations. When data is trapped in isolated infrastructure pockets, AI projects don't fail loudly; they stall and slip over budget, while teams shuffle data between systems instead of training models.
This is where VAST Data comes in. VAST AI OS on Azure unifies file, block, object, and real-time analytics in a single global namespace, giving you complete data visibility across your entire data estate, from edge to cloud.
Move from legacy constraints to AI possibilities.
Give Azure AI Services a Single Source of Truth
Turn governed, unified enterprise data into AI-driven results on Azure.
The Same VAST Data Services You Run On-Prem, in Azure
Your AI is only as good as the data behind it. On Azure, VAST on Cloud puts the full VAST AI OS to work, keeping business data near Azure GPUs and updating it in real time. So, your models use current, governed enterprise data for training and reasoning.
Storage-Optimized Virtual Machines
VAST AI OS runs on storage-optimized virtual machines with locally attached NVMe, delivering the low-latency, high-throughput performance that AI workloads demand.
Designed for Durability
Durability is front-and-center: metadata and the write buffer are mirrored to Azure managed disks, and a copy of the data is persisted to Blob Storage. This keeps the cluster recoverable, even if an entire Availability Zone goes down.
Data Locality Meets GPU Access
VAST DataSpace reconciles data access with GPU availability, keeping sensitive data in approved locations while giving authorized compute fast access through one global namespace, with strict consistency, local-speed reads, and governance built in.
Centralized Management of VAST AI OS
An automated control plane that manages every VAST cluster, whether on-premises or in Azure, handling automated provisioning, upgrades, self-healing, and right-sizing. Ensuring that capacity scales with business demand.
Enterprise Data Synchronization
Catalog and synchronize enterprise data from legacy storage arrays and cloud applications. AI services on Azure gain access to all your data, even outside the VAST AI OS.
Action the Moment Data Lands
The moment new data lands on the VAST DataStore, a trigger fires, processing and cataloging it automatically so it's ready to use. No polling, no batch delays, no models running on stale results.
