Why it's important: Clean, well-structured data is the foundation of any successful ML project. Vertex AI provides tools for data versioning and annotation.
Reminder: Take a short break if the post feels long.
2.2: Model Training – Auto ML vs. Custom Training
This is where the magic happens – teaching your model to learn from data! Vertex AI offers two primary approaches:
2.2.1: Auto ML – Low-Code/No-Code Machine Learning
What it is: Vertex AI Auto ML allows you to train high-quality models with minimal coding. You provide the data, and Vertex AI handles model architecture selection, hyperparameter tuning, and training.
When to use it: Ideal for users who are new to ML, have limited coding experience, or want to quickly prototype models. It's great for common tasks like image classification, object detection, tabular regression/classification, and text classification.
Key Benefit: Speed and simplicity!
2.2.2: Custom Training – Full Control for Experts
What it is: Custom Training provides the flexibility to train models using your own custom code (e.g., in TensorFlow, PyTorch, scikit-learn) on Vertex AI's managed infrastructure. You can specify the machine types, GPUs, and distributed training configurations.
When to use it: For users with ML expertise who need fine-grained control over their model architecture, training process, or want to leverage specific libraries not directly supported by Auto ML.
Key Benefit: Flexibility and power!
2.3: Model Management and Deployment
Once your model is trained, you need to manage it and make it accessible for predictions.
2.3.1: Model Registry
What it is: A centralized repository for managing your trained models. You can version models, track metadata, and organize them.
Why it's important: Essential for MLOps – ensuring you know which model version is deployed and for reproducibility.
2.3.2: Endpoints
What it is: A deployed version of your model that can serve predictions. When you deploy a model to an endpoint, Vertex AI provisions the necessary infrastructure.
How it works: You send data to the endpoint, and it returns predictions in real-time or via batch prediction.
2.4: Experiment Tracking and Monitoring
Experiment Tracking: Vertex AI Workbench and Experiments allow you to track model training runs, hyperparameters, and evaluation metrics, making it easier to compare and iterate on models.
Model Monitoring: Crucial for production models, Vertex AI Model Monitoring helps detect drift (when input data distribution changes) and skew (differences between training and serving data), ensuring your models remain accurate over time.
Step 3: Your First Vertex AI Model – A Hands-On Walkthrough (Auto ML Tabular Example)
Let's get practical! We'll start with an Auto ML tabular model as it's a fantastic way to grasp the core concepts without deep coding. Imagine we want to predict customer churn based on historical data.
3.1: Preparing Your Data
For this example, you'll need a CSV file with tabular data. Let's assume you have customer_data.csv with columns like age, gender, usage_minutes, contract_type, and a target column churn (0 for no churn, 1 for churn).
QuickTip: Reading regularly builds stronger recall.
Upload to Cloud Storage:
In the Google Cloud Console, navigate to "Cloud Storage" > "Buckets".
Click "CREATE BUCKET". Give it a unique name (e.g.,
my-vertex-ai-data-bucket-2025). Choose a region close to you.Once created, click on your bucket, then "UPLOAD FILES" and select your
customer_data.csv.
3.2: Creating a Vertex AI Dataset
Go to Vertex AI: In the Google Cloud Console, search for "Vertex AI" and select it.
Navigate to Datasets: In the left navigation pane, click on "Datasets".
Create a New Dataset:
Click "+ CREATE".
Choose "Tabular" as the data type.
Give your dataset a name (e.g.,
Customer Churn Prediction Data).Select the radio button "Select CSV file from Cloud Storage".
Browse to your bucket and select
gs://my-vertex-ai-data-bucket-2025/customer_data.csv.Click "CREATE".
Vertex AI will now import and analyze your data. This might take a few minutes.
3.3: Training Your Auto ML Model
Once your dataset is ready:
Initiate Training: On the Dataset details page, click "TRAIN NEW MODEL".
Model Training Method: Select "AutoML".
Training Details:
Model name:
customer-churn-automl-modelObjective: Select "Classification" (since
churnis 0 or 1).Target column: Select
churn.Columns to include/exclude: Vertex AI will automatically detect features. You can deselect any columns you don't want to use as features.
Training options:
Optimization objective: For classification, you might choose
AUCorLog loss.Training budget: This is crucial! It determines how long Vertex AI will train and therefore how much it might cost. For initial experimentation, start with a smaller budget (e.g., 1-4 hours).
Click "TRAIN".
This process will take time, depending on your data size and training budget. You can monitor its progress under "Models" > "Training."
3.4: Evaluating Your Model
Once training is complete, you'll receive a notification.
View Model Details: Navigate to "Models" in the Vertex AI console, then click on your newly trained model (
customer-churn-automl-model).Evaluation Metrics: Here you'll see a wealth of information:
AUC, Precision, Recall, F1-score: Key metrics for classification models.
Confusion Matrix: Shows true positives, true negatives, false positives, and false negatives.
Feature Importance: Very useful for understanding which features contributed most to the model's predictions.
Spend some time analyzing these metrics. A good model will have high scores for your chosen optimization objective.
Step 4: Deploying and Getting Predictions
Now that you have a trained model, let's make it useful!
4.1: Deploying Your Model to an Endpoint
Select Your Model: From the model's evaluation page, click "DEPLOY MODEL".
Create New Endpoint:
Endpoint name:
customer-churn-prediction-endpointModel settings:
Machine type: Choose an appropriate machine type (e.g.,
n1-standard-2). For initial testing, smaller machines are fine.Traffic split: Leave at 100% for now.
Min/Max replica count: Set both to 1 for cost efficiency during testing. For production, you might set a higher max replica count for scalability.
Click "DEPLOY".
Deployment can take several minutes as Vertex AI provisions the necessary infrastructure. You can monitor its status under "Endpoints."
4.2: Getting Online Predictions
Once your endpoint is deployed:
Go to Endpoints: Navigate to "Endpoints" in the Vertex AI console and click on your new endpoint.
Test Your Model:
On the "Endpoint details" page, click "TEST MODEL".
In the "Request" box, you'll see a JSON structure. Replace the placeholder data with values for a single customer you want to predict churn for. For example:
JSON{ "instances": [ { "age": 35, "gender": "male", "usage_minutes": 1500, "contract_type": "monthly", "monthly_bill": 50, "data_plan": "yes" } ] }Ensure your instance data matches the features your model was trained on.
Click "PREDICT".
The "Response" box will show the model's prediction (e.g., probability of churn).
Congratulations! You've just trained and deployed your first Vertex AI model and made a prediction. This is a huge milestone!
Step 5: Exploring More Advanced Vertex AI Features
While Auto ML is a great starting point, Vertex AI offers much more.
QuickTip: Read with curiosity — ask ‘why’ often.
5.1: Vertex AI Workbench – Your ML Development Environment
What it is: A managed Jupyter Notebook environment where you can write and execute your Python code, connect to datasets, and interact with Vertex AI APIs.
Why use it: Ideal for custom model training, data exploration, and iterative development.

Bashpip install google-cloud-aiplatformAuthenticate (if local):
Bashgcloud auth application-default loginYour Custom Training Script: Write a Python script (e.g.,
trainer.py) that includes your model definition, training loop, and saves the trained model artifact to a Cloud Storage bucket.Submit Training Job: From your Python code or
gcloudCLI:Pythonfrom google.cloud import aiplatform aiplatform.init(project='your-gcp-project-id', location='your-gcp-region') # Define your custom training job job = aiplatform.CustomContainerTrainingJob( display_name='my-custom-model-training', container_uri='gcr.io/cloud-aiplatform/training/tf-cpu.2-10.py3', # Or your custom container model_serving_container_image_uri='gcr.io/cloud-aiplatform/prediction/tf-cpu.2-10.py3', # Or your custom container # ... other parameters like data sources, hyperparameters ) # Run the training job model = job.run( replica_count=1, machine_type='n1-standard-4', # ... more parameters ) # Deploy the model after training endpoint = model.deploy(machine_type="n1-standard-2")This provides immense flexibility for complex models and workflows.
5.3: Pipelines and MLOps
Vertex AI Pipelines: Orchestrate your ML workflow (data preprocessing, training, evaluation, deployment) into automated, reproducible pipelines using Kubeflow Pipelines. This is critical for productionizing ML.
Vertex AI Feature Store: A centralized repository for serving, sharing, and managing ML features, ensuring consistency between training and serving.
Step 6: Monitoring and Iteration – The MLOps Mindset
Your journey doesn't end after deployment. Machine learning models require continuous monitoring and iteration to remain effective.

Click "CREATE MONITOR JOB".
Configure parameters like skew/drift thresholds, sampling rate, and alerting mechanisms.
Why it matters: Models degrade over time! Monitoring helps you proactively identify when your model's performance is declining due to changes in data distribution, allowing you to retrain and redeploy.
6.2: Retraining and Redeployment
When monitoring indicates drift or new data becomes available:
Retrain your model: Use your updated dataset or refined training scripts to train a new version of your model (either Auto ML or custom).
Evaluate the new model: Compare its performance with the currently deployed version.
Deploy the new version: You can deploy the new model to the same endpoint with a traffic split to gradually shift traffic, or create a new endpoint for A/B testing. Vertex AI provides robust versioning and traffic management.
Step 7: Managing Costs and Resources
Vertex AI offers powerful resources, but it's important to be mindful of costs.
Monitor Billing: Regularly check your Google Cloud billing dashboard to track your spending.
Delete Unused Resources:
Endpoints: Undeploy models from endpoints when they are not needed. You are charged for deployed endpoints even if they are not actively serving predictions.
Notebook Instances: Shut down or delete Workbench instances when you're not using them.
Datasets: Delete datasets if they are no longer needed.
Models: While models themselves don't incur significant storage costs, managing many versions can add up.
Cloud Storage: Delete unnecessary files from your Cloud Storage buckets.
Free Tier: Take advantage of the Google Cloud Free Tier for initial experimentation.
Resource Quotas: Be aware of your project's quotas to avoid hitting limits. You can request increases if needed.
