AI/ML Workloads on Kubernetes: Running Scalable Machine Learning Pipelines with GPU Acceleration and Distributed Training

The rise of Artificial Intelligence (AI) and Machine Learning (ML) has fundamentally transformed how businesses operate. From real-time personalization to advanced predictive analytics, ML is powering innovation across industries.

However, with increased adoption comes operational complexity. As ML systems scale, they demand robust infrastructure—one that supports scalability, reproducibility, resource optimization, and distributed computation.

Enter Kubernetes: the cloud-native container orchestration platform that is rapidly becoming the standard infrastructure for ML workloads.

In this blog, we at Ananta Cloud will show you how to:

• Deploy scalable ML pipelines on Kubernetes

• Accelerate training with GPUs

• Enable distributed training with popular frameworks like TensorFlow and PyTorch

• Use open-source tools such as Kubeflow, KEDA, and NVIDIA GPU Operator

Why Use Kubernetes for ML Workloads?

Traditionally, machine learning has been limited to local experimentation or static virtual machines. But Kubernetes introduces key benefits:

Feature	Benefit for ML
Scalability	Auto-scale workloads across clusters and nodes
Resource Management	Efficient use of CPUs, GPUs, and memory
Portability	Consistent environments across cloud/on-prem
Reproducibility	ML pipelines as code (CI/CD for models)
Isolation	Run experiments in isolated containers
Automation	Trigger pipelines on data or code changes

Kubernetes transforms ML development from a manual process to an automated, reproducible pipeline, bringing engineering best practices into data science workflows.

Use Case Overview: Ananta Cloud ML Platform on Kubernetes

At Ananta Cloud, we help organizations build ML infrastructure using a Kubernetes-native stack. Here’s a high-level architecture:

[Data Sources] --> [Data Processing (Apache Spark, Dask)] 
                 --> [Model Training (TensorFlow, PyTorch)] 
                 --> [Model Serving (KFServing, Triton Inference Server)]
                 --> [Monitoring (Prometheus, Grafana)]

All components run containerized on Kubernetes, integrated with:

• GPU acceleration (via NVIDIA Operator)

• ML pipeline orchestration (via Kubeflow or Argo Workflows)

• Distributed training using MPI, Horovod, or native frameworks

Let’s break this down further.

Building ML Pipelines with Kubeflow

Kubeflow is a Kubernetes-native platform to build, train, and deploy ML models at scale. It abstracts complex infrastructure into simple building blocks.

Example Pipeline

Let’s define a typical ML pipeline:

1. Data Ingestion – Load data from S3, GCS, or HDFS.

2. Preprocessing – Clean and transform using a Python script or Spark job.

3. Training – Train models using TensorFlow, PyTorch, or XGBoost.

4. Validation – Evaluate and test model accuracy.

5. Serving – Deploy to a live endpoint for predictions.

Example Kubeflow Pipeline YAML

import kfp.dsl as dsl

@dsl.pipeline(
    name='ML Pipeline Example',
    description='An example ML pipeline running on Kubernetes'
)
def ml_pipeline():
    preprocess = dsl.ContainerOp(
        name='Preprocess Data',
        image='anantacloud/preprocess:latest',
        arguments=['--input', '/data/input.csv']
    )
    
    train = dsl.ContainerOp(
        name='Train Model',
        image='anantacloud/train:latest',
        arguments=['--epochs', '10', '--batch-size', '32']
    )
    train.after(preprocess)
    
    deploy = dsl.ContainerOp(
        name='Deploy Model',
        image='anantacloud/deploy:latest'
    )
    deploy.after(train)

Kubeflow automatically creates and manages this pipeline, including dependencies and resource scheduling.

GPU Acceleration in Kubernetes

ML model training, especially deep learning, is compute-intensive and benefits greatly from GPUs.

How to Enable GPU Support:

1. Install NVIDIA Drivers

   • Use NVIDIA GPU Operator to automatically install the driver, runtime, and monitoring tools.

kubectl create -f https://raw.githubusercontent.com/NVIDIA/gpu-operator/main/deployments/gpu-operator.yaml

2. Label GPU Nodes

kubectl label node <node-name> nvidia.com/gpu=true

3. Create a GPU-enabled Pod

apiVersion: v1
kind: Pod
metadata:
  name: gpu-train-job
spec:
  containers:
  - name: trainer
    image: anantacloud/tensorflow-train:gpu
    resources:
      limits:
        nvidia.com/gpu: 1

Kubernetes will schedule the job on a node with available GPU resources.

Distributed Training with TensorFlow & PyTorch

Training large models or datasets often requires multiple GPUs across nodes. Kubernetes supports this using distributed training frameworks like:

• Horovod: AllReduce-based training for TensorFlow, PyTorch, Keras

• TFJob: Native Kubeflow support for TensorFlow distributed jobs

• MPIJob: General-purpose parallel training

Example: Distributed TensorFlow with TFJob

apiVersion: kubeflow.org/v1
kind: TFJob
metadata:
  name: tfjob-dist
spec:
  tfReplicaSpecs:
    Worker:
      replicas: 2
      template:
        spec:
          containers:
          - name: tensorflow
            image: anantacloud/tf-train:latest
            resources:
              limits:
                nvidia.com/gpu: 1

This defines a job with two TensorFlow workers, each using a GPU. Kubernetes ensures data locality and network communication via services.

Real-time Model Serving on Kubernetes

After training, models can be served using scalable, production-ready solutions like:

• KFServing (KServe) – Scales model endpoints automatically

• Triton Inference Server – Optimized GPU-based serving by NVIDIA

• Seldon Core – Extensible model deployment framework

Example KFServing Deployment

apiVersion: serving.kserve.io/v1beta1
kind: InferenceService
metadata:
  name: ananta-ml-model
spec:
  predictor:
    tensorflow:
      storageUri: s3://bucket/tf-model/

Kubernetes handles autoscaling, A/B testing, and monitoring via integration with Prometheus and Grafana.

Auto-scaling ML Workloads with KEDA

When you need to scale training or inference dynamically, use KEDA (Kubernetes Event-Driven Autoscaling). It allows scaling based on:

• Kafka queue depth

• Prometheus metrics

• Redis queue size

• Custom metrics

Example: Scale TensorFlow workers on queue size

apiVersion: keda.sh/v1alpha1
kind: ScaledObject
metadata:
  name: tf-scaled
spec:
  scaleTargetRef:
    name: tfjob-worker
  triggers:
  - type: prometheus
    metadata:
      serverAddress: http://prometheus-service
      metricName: queue_depth
      threshold: '10'

Monitoring and Logging

At Ananta Cloud, we integrate:

• Prometheus + Grafana – Metrics and dashboards

• Elasticsearch + Fluentd + Kibana (EFK) – Logs and query support

These ensure full observability of your ML systems.
