Why GPU Selection Is No Longer Optional

As the demand for accelerated computing explodes across industries — from AI/ML to scientific simulation and 3D rendering — GPUs have become the new compute backbone. But raw power isn’t enough. With the surge of GPU offerings, architectures, and deployment models, choosing the right GPU can be technically overwhelming and financially risky.

That’s where Ananta Cloud steps in. We don’t just provide GPU infrastructure — we architect, deploy, and optimize it with a GPU-as-a-Service (GPUaaS) approach tailored to your unique workloads and business goals.

What is GPU-as-a-Service?

GPUaaS lets businesses access GPU compute on-demand — without managing physical hardware, drivers, or scaling challenges. Through cloud abstraction, automation, and deep workload analysis, Ananta Cloud enables organizations to:

Deploy the right GPU in the right configuration
Avoid CapEx and underutilization
Accelerate time-to-value for AI, HPC, and visualization projects
Optimize cost-performance with tailored consumption models

Ananta Cloud Framework for GPU Selection

We follow a consulting-led, data-driven framework to match workloads to optimal GPU infrastructure:

01 - Understand the Workload Profile

Before touching infrastructure, we assess:

Dimension	Examples
Workload Type	AI/ML training, real-time inference, rendering, simulations
Precision Requirements	FP32, TF32, FP16, INT8, FP64
Data Characteristics	Batch size, input resolution, model size
Runtime Constraints	Real-time latency, throughput targets, job durations
Scalability Needs	Multi-GPU, multi-node, cross-region deployment

Example: A client training LLMs benefits from NVLink-connected H100s. A company running edge inference at scale might benefit more from L4 or T4 GPUs.

02 - Match Technical Specs to Workload Requirements

Here’s how we break down the GPU architecture vs workload mapping:

GPU Feature	Ideal For
Tensor Cores (TF32/FP16/INT8)	Deep learning training & inference
FP64 Throughput	Scientific computing, simulations
Ray Tracing (RT Cores)	Visualization, 3D rendering
Multi-Instance GPU (MIG)	Virtualized AI inference, multi-tenant environments

03 - Determine Interconnect & Scalability Needs

Multi-GPU and multi-node configurations require high-speed interconnects:

Interconnect	Use Case
NVLink / NVSwitch	Large-scale training (e.g. GPT, diffusion models)
PCIe Gen4/5	Inference, light parallel workloads
InfiniBand	HPC or distributed training over multiple nodes

Ananta Cloud helps you assess whether your workload needs GPU clustering, or whether single-GPU parallelism suffices.

04 - Balance Cost with Performance

We guide clients through Total Cost of Execution (TCoE) — not just cost per hour.

GPU	Training Power	Price/hr	Best Use Case
H100 80GB	High	$5.50–$6.00	LLM training, diffusion
A100 80GB	Mid	$3.90–$4.50	Vision AI, tabular ML
L4 / T4	Low	$0.50–$0.90	Inference, lightweight training
MI300X	High (FP64)	Custom	HPC, science, hybrid AI-HPC

We help you avoid overprovisioning — and underperformance.

GPU Deployment Models with Ananta Cloud

Model	Description	Best For
GPUaaS - Shared	Pay-per-use GPU pool	Startups, batch jobs
GPUaaS - Dedicated	Reserved capacity	Training pipelines, steady workloads
GPUaaS - Clustered	Multi-GPU per node	LLMs, HPC
Bare Metal GPU Nodes	Full control, max perf	Custom environments
On-Prem Advisory	Hybrid consulting	Regulated industries, latency-sensitive

Ananta Cloud helps clients deploy across multi-cloud, private cloud, or hybrid environments — with centralized control.

Sample Use Cases

01 - Startup Training Multilingual LLM

Need: 8x H100 w/ NVSwitch for distributed training
Ananta Solution: Dedicated GPUaaS cluster, Dockerized training stack, autoscaling
Outcome: Model trained 35% faster, infra cost reduced via spot GPU blending

02 - Enterprise Building Real-Time AI Inference Pipeline

Need: Low-latency INT8 inference at scale
Ananta Solution: vGPU-backed L4 instances + K8s + Triton Inference Server
Outcome: 60% cost savings over CPU baseline, SLA met consistently

03 - Research Lab Running Quantum Simulations

Need: High FP64 throughput, ECC memory, long-duration compute
Ananta Solution: AMD MI300X-based cluster with InfiniBand
Outcome: 3.5x speedup vs CPU, without managing infrastructure

Final Thoughts: GPU Selection is a Strategy, not a Purchase

The explosion of options in GPU hardware, software, and cloud configurations means you need more than hardware specs - you need a partner that understands your workload, your constraints, and your roadmap.
