How Does GPU Virtualization Work in GaaS?

GPU virtualization in GPU-as-a-Service (GaaS) enables multiple users to securely share a single physical GPU by dividing its resources into isolated virtual instances through a hypervisor or orchestration layer, allowing efficient scaling for AI, rendering, and data-intensive tasks without performance loss.​

Core Mechanism

GPU virtualization operates via a layered architecture starting with physical GPU hardware featuring parallel processing cores. A virtualization layer, managed by hypervisors like VMware vSphere or Kubernetes orchestrators, partitions these resources into virtual GPUs (vGPUs) for simultaneous multi-user access. Cyfuture Cloud leverages this in GaaS to provision environments automatically—users specify needs like A100 GPUs and RAM, and the system allocates shares securely, preventing interference.​

Key techniques include:

Mediated Pass-Through: Hypervisor uses IOMMU to assign virtual memory contexts per VM, forwarding commands directly to hardware for near-native performance.​

Resource Allocation: Hypervisor schedules vGPUs based on demand, using profiles for workloads like AI training or simulations.​

API Integration: Tools like CUDA or ROCm translate user tasks to GPU instructions, executed concurrently across cores.​

Cyfuture Cloud Implementation

In Cyfuture Cloud's GaaS, orchestration automates lifecycle management of GPU-accelerated containers, eliminating manual VM setup. This supports scalable deployments for enterprise AI/ML, rendering, and HPC, with dynamic scaling to match fluctuating needs. Virtualization ensures isolation, enabling remote teams to collaborate on high-performance tasks without owning hardware.​

Benefits include cost savings via pay-per-use, maintenance offloading, and flexibility over on-premise setups, where Cyfuture handles updates and security.​

Use Cases and Best Practices

Common applications encompass AI model training, real-time inference, 3D rendering, and data analytics, all optimized by Cyfuture Cloud's infrastructure. Best practices involve workload-specific vGPU profiles, resource pooling for bursts, and NUMA affinity to minimize latency.​
