VectorLay vs Azure
Microsoft Azure offers GPU VMs through NC and ND-series instances, Azure Machine Learning for managed inference, and Azure OpenAI Service for foundation models. Here's how it stacks up against VectorLay for GPU inference workloads.
TL;DR
- →VectorLay is 52-80% cheaper for GPU inference
- →Azure excels at enterprise — Active Directory, hybrid cloud, compliance
- →Azure OpenAI Service gives exclusive access to GPT models — VectorLay focuses on open-source
- →VectorLay is zero-config — no subscription setup, AD tenant, or resource groups
Overview
Azure is the cloud of choice for enterprises already in the Microsoft ecosystem. Azure Machine Learning integrates with Visual Studio, GitHub, and Active Directory. The Azure OpenAI Service provides managed access to GPT-4, DALL·E, and other OpenAI models with enterprise security.
For teams running their own open-source models, though, Azure GPU VMs are among the most expensive options available. NC-series (T4), ND-series (A100), and the newer ND H100 v5 instances carry premium price tags, and the Azure portal's complexity adds engineering overhead.
VectorLay offers a radically simpler path: deploy your container, pick your GPU, and pay per hour. Built-in fault tolerance handles reliability so you don't need to architect it yourself.
Pricing Comparison
| GPU | VectorLay | Azure | Savings |
|---|---|---|---|
| RTX 4090 (24GB) | $0.49/hr | N/A | — |
| RTX 3090 (24GB) | $0.29/hr | N/A | — |
| T4 equiv (16GB) | $0.29/hr | $0.526/hr (NC4as T4 v3) | 45% |
| A100 (80GB) | $1.64/hr | $3.40/hr (ND96asr A100 v4 per GPU) | 52% |
| H100 (80GB) | $2.49/hr | ~$12.40/hr (ND H100 v5 per GPU) | 80% |
Azure prices are pay-as-you-go as of January 2026. Azure Reserved VM Instances (1yr/3yr) can reduce costs by 36-57%. Azure ND-series VMs are multi-GPU; per-GPU price is calculated from the total instance price.
Feature Comparison
| Feature | VectorLay | Azure |
|---|---|---|
| Setup Complexity | Minimal — sign up and deploy | Subscription → Resource Group → NSG → VM → Disk |
| Auto-Failover | Built-in overlay network | Azure Load Balancer + VMSS |
| OpenAI Models | Open-source models only | Azure OpenAI Service (GPT-4, etc.) |
| Enterprise Identity | API key auth | Active Directory / Entra ID |
| Consumer GPUs | RTX 4090, RTX 3090 | Not available |
| Billing Surprises | None — flat GPU-hour pricing | Managed disk, network, premium SSD add up |
When to Choose Azure
- Enterprise with Active Directory / Entra ID requirements
- Need Azure OpenAI Service for GPT-4 / DALL·E access
- Hybrid cloud with on-prem Azure Stack integration
- Government or regulated industry compliance (FedRAMP, HIPAA)
When to Choose VectorLay
- Running open-source models (Llama, Mistral, SDXL, Whisper)
- Cost is a primary concern — save 52-80%
- Don't want to deal with Azure portal complexity
- Need built-in fault tolerance without VMSS/Load Balancer setup
- Startup or indie developer who doesn't need enterprise AD
Bottom Line
Azure is built for enterprises that live in the Microsoft world. If you need Active Directory integration, Azure OpenAI Service, or government compliance, Azure is the way to go — but you'll pay premium prices for GPU access.
For teams focused on running open-source model inference at scale, VectorLay is the smarter economic choice. You get comparable GPU performance at 52-80% lower cost, with fault tolerance that comes free instead of requiring weeks of infrastructure engineering.
