Deploying an MLOps Pipeline on Microsoft Fabric with Azure Databricks

Introduction

Machine learning operations (MLOps) represents one of the most critical capabilities for modern enterprises seeking to operationalise artificial intelligence at scale. As organisations across Australia and the Asia-Pacific region increasingly recognise the strategic value of data-driven decision-making, the demand for robust, scalable MLOps infrastructure has grown exponentially. Microsoft Fabric and Azure Databricks together provide a powerful, integrated platform for building, deploying, and managing machine learning pipelines that can drive measurable business outcomes.

This comprehensive tutorial walks you through the practical steps of deploying a complete MLOps pipeline on Microsoft Fabric with Azure Databricks integration. Whether you’re a data architect, platform engineer, or AI/MLOps lead evaluating Microsoft’s modern analytics stack, this guide provides the hands-on knowledge you need to architect and implement enterprise-grade machine learning workflows.

At Agile Insights, we’ve helped dozens of Australian enterprises modernise their data and analytics platforms using Microsoft Fabric and Azure Databricks. This tutorial reflects real-world implementation patterns and best practices we’ve developed through extensive customer engagements.

Understanding the MLOps Architecture

Before diving into deployment steps, it’s essential to understand the architectural components that comprise a modern MLOps pipeline on Microsoft Fabric and Azure Databricks. MLOps encompasses the entire lifecycle of machine learning systems, from data ingestion and preparation through model training, evaluation, deployment, and ongoing monitoring.

Microsoft Fabric serves as your unified analytics platform, providing a single, cohesive experience across data engineering, analytics, and business intelligence. Azure Databricks, built on Apache Spark, delivers the compute power and data processing capabilities necessary for large-scale machine learning workloads. When integrated effectively, these platforms create a seamless environment where data engineers can prepare data, data scientists can experiment and train models, and MLOps engineers can automate deployment and monitoring.

The integration between Microsoft Fabric and Azure Databricks enables you to leverage top approaches to integrating Azure Databricks with Microsoft Fabric, which include direct workspace connections, mirrored catalogs, and unified data governance. Understanding these integration patterns is fundamental to designing a resilient, scalable MLOps architecture that meets enterprise requirements for security, governance, and performance.

Prerequisites and Setup Requirements

Successful deployment of an MLOps pipeline requires careful preparation and validation of prerequisites. This section outlines everything you need in place before beginning the hands-on implementation steps.

Azure Subscription and Resource Configuration

You’ll need an active Azure subscription with appropriate permissions to create and manage resources. At minimum, you should have Contributor or Owner role access to the subscription where you’ll deploy resources. Create a dedicated resource group for your MLOps infrastructure, which will help with cost tracking, access control, and lifecycle management.

Within your Azure subscription, ensure you have quota available for Azure Databricks clusters. Standard deployments typically require at least 8 vCPU quota for compute resources. If you’re planning larger-scale implementations, verify that your subscription has sufficient quota; you can request quota increases through the Azure portal if needed.

Microsoft Fabric Capacity and Workspace Setup

Microsoft Fabric requires a capacity subscription, which can be purchased through the Azure portal or Microsoft 365 admin centre. For development and testing, a trial capacity provides sufficient resources; for production workloads, you’ll typically need a paid capacity (F64 or higher, depending on workload volume).

Once capacity is provisioned, create a dedicated workspace within Fabric. This workspace will serve as your central hub for all analytics, data engineering, and MLOps activities. Ensure you have Workspace Admin permissions in Fabric, as you’ll need to configure workspace settings, manage data sources, and establish governance policies.

Azure Databricks Workspace Provisioning

Provision an Azure Databricks workspace in the same Azure region as your Microsoft Fabric capacity. This co-location reduces latency and simplifies network configuration. During workspace creation, select the appropriate pricing tier (Standard or Premium; Premium is recommended for production MLOps workloads due to enhanced security and compliance features).

After workspace provisioning completes, generate a personal access token in Databricks. Navigate to User Settings in your Databricks workspace, select “Developer” and then “Personal access tokens”, and generate a new token with appropriate scopes. Store this token securely, as you’ll use it for programmatic access and integration with other services.

Azure Data Lake Storage Gen2 Configuration

Azure Data Lake Storage Gen2 (ADLS Gen2) serves as the primary data repository for your MLOps pipeline. Create a storage account with ADLS Gen2 enabled in the same region as your Databricks workspace. Within the storage account, create container hierarchies that reflect your data organisation: raw data ingestion, processed data, model artifacts, and pipeline logs.

Configure appropriate access controls using Azure role-based access control (RBAC). Assign the “Storage Blob Data Contributor” role to your Databricks workspace’s managed identity, enabling seamless authentication without credential management. This approach aligns with security best practices and simplifies operational management.

For detailed guidance on connecting your Databricks workspace to Azure Data Lake Storage, refer to the Azure Databricks documentation on connecting to Azure Data Lake Storage Gen2, which provides comprehensive instructions for various authentication methods.

Networking and Security Configuration

Ensure your Azure Databricks workspace and ADLS Gen2 account are configured to communicate securely. If using private endpoints, configure them appropriately and ensure your Databricks workspace has network access through virtual network peering or equivalent connectivity.

Configure network security groups (NSGs) to allow necessary traffic between services. At minimum, allow outbound HTTPS traffic from Databricks to Azure services and the internet for downloading packages and libraries.

Enable Azure Purview integration for data governance. Agile Insights recommends implementing data governance frameworks from the outset, as retroactive governance implementation becomes exponentially more complex at scale. Configure Purview to catalog your data assets and establish data lineage tracking across your MLOps pipeline.

Development Tools and Libraries

Install the following tools on your local development machine:

• Python 3.9 or higher (3.10 or 3.11 recommended)
• Azure CLI (for managing Azure resources)
• Databricks CLI (for workspace management and job deployment)
• Git (for version control)
• Visual Studio Code or your preferred IDE with Python extensions

Within your Python environment, install essential libraries:

pip install databricks-sdk azure-identity azure-storage-blob pyspark scikit-learn pandas numpy mlflow

These libraries provide the foundation for interacting with Databricks, Azure services, machine learning workflows, and experiment tracking.

Step 1: Setting Up Your Databricks Workspace and Clusters

With prerequisites in place, begin by configuring your Databricks workspace for MLOps workloads. This step establishes the compute infrastructure and workspace settings that will support your machine learning pipeline.

Creating a Compute Cluster

In your Databricks workspace, navigate to the Compute section and create a new cluster. Use the following configuration as a starting point:

• Cluster Mode: Multi-node (for distributed processing)
• Databricks Runtime: Latest Databricks Runtime with ML support (e.g., 13.x ML)
• Node Type: StandardDS4v2 or equivalent (8 vCPU, 28 GB RAM)
• Number of Workers: 2-4 nodes (scale based on your data volume)
• Auto-termination: Enable after 30 minutes of inactivity to control costs

The ML runtime includes pre-installed libraries for machine learning, including scikit-learn, XGBoost, and MLflow, which streamlines your development workflow.

Configuring Cluster Spark Configuration

Optimise your cluster by adding the following Spark configuration in the Advanced Options:

spark.databricks.cluster.profile singleNode
spark.sql.shuffle.partitions 200
spark.databricks.adaptive.autoPartitionSolving.enabled true

These settings optimise query performance and enable adaptive query execution, which automatically adjusts partition counts based on data characteristics.

Installing Required Libraries

Once your cluster is running, install additional libraries required for your MLOps pipeline. In the Cluster Libraries section, add the following PyPI packages:

• mlflow: For experiment tracking and model registry
• delta: For Delta Lake table operations
• azure-storage-blob: For Azure Storage integration
• azure-identity: For Azure authentication
• pydantic: For data validation
• pytest: For unit testing

Step 2: Integrating Azure Databricks with Microsoft Fabric

The integration between Azure Databricks and Microsoft Fabric enables seamless data movement and unified governance. This step establishes the connection and configures mirrored catalogs.

Enabling Mirrored Databases

Microsoft Fabric supports mirroring Azure Databricks catalogs, providing a unified data view across platforms. This capability, detailed in the Microsoft Fabric Mirrored Databases From Azure Databricks Tutorial, allows you to access Databricks data directly from Fabric without replication.

To enable mirroring, first ensure your Databricks workspace is configured with Unity Catalog. Unity Catalog provides fine-grained access control and data governance across your analytics platform. In Databricks, navigate to Admin Settings and enable Unity Catalog for your workspace.

Create a metastore in Databricks linked to your Azure Data Lake Storage account. This metastore serves as the central repository for table metadata and access control policies.

Configuring Fabric Connections

In Microsoft Fabric, navigate to your workspace settings and configure a new connection to your Databricks workspace. Provide:

• Databricks workspace URL
• Databricks personal access token (created during prerequisites)
• Default catalog name (typically “hive_metastore” initially)

Once connected, Fabric will display available Databricks catalogs and tables, enabling direct querying from Power BI and Fabric notebooks.

Establishing Data Lineage

Configure data lineage tracking to visualise how data flows through your MLOps pipeline. In Fabric, enable Lineage view in your workspace. As your pipeline executes, Fabric will automatically track data transformations and model inputs/outputs, creating a comprehensive audit trail.

This lineage information proves invaluable for compliance, troubleshooting, and understanding data dependencies across your analytics ecosystem.

Step 3: Building Your Data Preparation Pipeline

MLOps success depends fundamentally on data quality and preparation. This step walks through building a robust data preparation pipeline using Databricks notebooks.

Creating a Databricks Notebook

In your Databricks workspace, create a new Python notebook named “01datapreparation.py”. This notebook will handle data ingestion, validation, and transformation.

Begin with imports and authentication setup:

import pyspark.sql.functions as F
from pyspark.sql.types import StructType, StructField, StringType, DoubleType, IntegerType
from azure.identity import DefaultAzureCredential
from azure.storage.blob import BlobServiceClient
import mlflow
import logging

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

# Set MLflow experiment
mlflow.set_experiment("/Shared/mlops_pipeline")

Ingesting Data from Azure Data Lake

Read data from your ADLS Gen2 account:

# Read data from ADLS Gen2
data_path = "abfss://raw-data@yourstorageaccount.dfs.core.windows.net/input_data/"

df = spark.read.format("parquet").load(data_path)

logger.info(f"Loaded {df.count()} records from {data_path}")
logger.info(f"Schema: {df.schema}")

# Display sample data
display(df.limit(10))

Data Validation and Quality Checks

Implement comprehensive data quality validation:

# Check for null values
null_counts = df.select([F.count(F.when(F.col(c).isNull(), c)).alias(c) for c in df.columns])
logger.info("Null value counts:")
display(null_counts)

# Check for duplicates
duplicate_count = df.count() - df.distinct().count()
logger.info(f"Duplicate records: {duplicate_count}")

# Validate data types
for field in df.schema:
    logger.info(f"{field.name}: {field.dataType}")

# Remove duplicates and handle nulls
df_clean = df.dropDuplicates().na.drop(subset=['critical_column'])
logger.info(f"Records after cleaning: {df_clean.count()}")

Feature Engineering

Create derived features necessary for model training:

from pyspark.sql.functions import col, when, datediff, current_date

# Create temporal features
df_features = df_clean.withColumn(
    "days_since_event",
    datediff(current_date(), col("event_date"))
).withColumn(
    "is_weekend",
    when(F.dayofweek(col("event_date")).isin([1, 7]), 1).otherwise(0)
)

# Create categorical features
df_features = df_features.withColumn(
    "amount_category",
    when(col("amount") < 100, "low")
    .when(col("amount") < 1000, "medium")
    .otherwise("high")
)

logger.info("Feature engineering completed")
display(df_features.limit(5))

Saving Processed Data

Write processed data to Delta Lake for efficient querying and versioning:

# Save to Delta Lake
output_path = "abfss://processed-data@yourstorageaccount.dfs.core.windows.net/features/"

df_features.write 
    .format("delta") 
    .mode("overwrite") 
    .save(output_path)

logger.info(f"Processed data saved to {output_path}")

# Create managed table for easy access
spark.sql(f"""
    CREATE TABLE IF NOT EXISTS mlops_features
    USING DELTA
    LOCATION '{output_path}'
""")

Step 4: Implementing Model Training and Experiment Tracking

With prepared data in place, implement the model training pipeline with comprehensive experiment tracking using MLflow.

Creating the Training Notebook

Create a new notebook named “02modeltraining.py”:

import mlflow
import mlflow.sklearn
from sklearn.model_selection import train_test_split, cross_val_score
from sklearn.ensemble import RandomForestClassifier
from sklearn.preprocessing import StandardScaler
from sklearn.metrics import accuracy_score, precision_score, recall_score, f1_score, confusion_matrix
import pandas as pd
import numpy as np
import logging

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

# Set experiment for tracking
mlflow.set_experiment("/Shared/mlops_pipeline")

Loading and Preparing Training Data

Load the processed features created in the previous step:

# Load features from Delta Lake
df_features = spark.sql("SELECT * FROM mlops_features")

# Convert to Pandas for scikit-learn
pdf = df_features.toPandas()

logger.info(f"Loaded {len(pdf)} records for training")
logger.info(f"Features: {pdf.columns.tolist()}")

# Separate features and target
X = pdf.drop(columns=['target_column', 'id_column'])
y = pdf['target_column']

logger.info(f"Feature matrix shape: {X.shape}")
logger.info(f"Target distribution:n{y.value_counts()}")

Implementing Model Training with MLflow

Train multiple model variants and track experiments:

# Split data
X_train, X_test, y_train, y_test = train_test_split(
    X, y, test_size=0.2, random_state=42, stratify=y
)

logger.info(f"Training set size: {len(X_train)}")
logger.info(f"Test set size: {len(X_test)}")

# Scale features
scaler = StandardScaler()
X_train_scaled = scaler.fit_transform(X_train)
X_test_scaled = scaler.transform(X_test)

# Train model with MLflow tracking
with mlflow.start_run(run_name="random_forest_baseline"):
    # Log parameters
    params = {
        "n_estimators": 100,
        "max_depth": 10,
        "min_samples_split": 5,
        "random_state": 42
    }
    mlflow.log_params(params)
    
    # Train model
    model = RandomForestClassifier(**params)
    model.fit(X_train_scaled, y_train)
    
    # Make predictions
    y_pred = model.predict(X_test_scaled)
    
    # Calculate metrics
    accuracy = accuracy_score(y_test, y_pred)
    precision = precision_score(y_test, y_pred, average='weighted')
    recall = recall_score(y_test, y_pred, average='weighted')
    f1 = f1_score(y_test, y_pred, average='weighted')
    
    # Log metrics
    mlflow.log_metrics({
        "accuracy": accuracy,
        "precision": precision,
        "recall": recall,
        "f1_score": f1
    })
    
    # Log model
    mlflow.sklearn.log_model(model, "random_forest_model")
    
    logger.info(f"Model trained: Accuracy={accuracy:.4f}, F1={f1:.4f}")

Hyperparameter Tuning

Implement systematic hyperparameter optimisation:

from sklearn.model_selection import GridSearchCV

# Define parameter grid
param_grid = {
    'n_estimators': [50, 100, 200],
    'max_depth': [5, 10, 15],
    'min_samples_split': [2, 5, 10]
}

# Grid search
with mlflow.start_run(run_name="hyperparameter_tuning"):
    grid_search = GridSearchCV(
        RandomForestClassifier(random_state=42),
        param_grid,
        cv=5,
        scoring='f1_weighted',
        n_jobs=-1
    )
    
    grid_search.fit(X_train_scaled, y_train)
    
    best_model = grid_search.best_estimator_
    best_params = grid_search.best_params_
    
    # Log best parameters
    mlflow.log_params(best_params)
    
    # Evaluate on test set
    y_pred_best = best_model.predict(X_test_scaled)
    best_f1 = f1_score(y_test, y_pred_best, average='weighted')
    
    mlflow.log_metric("best_f1_score", best_f1)
    mlflow.sklearn.log_model(best_model, "best_random_forest")
    
    logger.info(f"Best parameters: {best_params}")
    logger.info(f"Best F1 Score: {best_f1:.4f}")

Step 5: Deploying Models to Databricks Model Registry

Once trained and validated, register your models in Databricks Model Registry for version control and deployment management.

Registering Models

Register your best model:

model_name = "mlops_production_model"

# Register model
model_uri = f"runs:/{mlflow.active_run().info.run_id}/best_random_forest"
model_details = mlflow.register_model(model_uri, model_name)

logger.info(f"Model registered: {model_name}, Version: {model_details.version}")

Setting Model Stages

Manage model lifecycle through stages:

from mlflow.entities.model_registry.model_version_status import ModelVersionStatus

# Transition model to Staging
mlflow.set_model_version_tag(
    name=model_name,
    version=model_details.version,
    key="stage",
    value="staging"
)

# Move to Production after validation
mlflow.transition_model_version_stage(
    name=model_name,
    version=model_details.version,
    stage="Production"
)

logger.info(f"Model {model_name} v{model_details.version} transitioned to Production")

Step 6: Building Automated MLOps Workflows with Databricks Jobs

Automate your entire pipeline through Databricks Jobs, ensuring consistent, reproducible execution.

Creating Job Configuration

Create a job configuration file (job_config.json):

{
  "name": "mlops_pipeline_daily",
  "description": "End-to-end MLOps pipeline execution",
  "tasks": [
    {
      "task_key": "data_preparation",
      "notebook_task": {
        "notebook_path": "/Users/your-email@company.com/01_data_preparation",
        "base_parameters": {
          "environment": "production"
        }
      },
      "existing_cluster_id": "your-cluster-id",
      "timeout_seconds": 3600
    },
    {
      "task_key": "model_training",
      "depends_on": [
        {
          "task_key": "data_preparation"
        }
      ],
      "notebook_task": {
        "notebook_path": "/Users/your-email@company.com/02_model_training",
        "base_parameters": {
          "environment": "production"
        }
      },
      "existing_cluster_id": "your-cluster-id",
      "timeout_seconds": 7200
    },
    {
      "task_key": "model_evaluation",
      "depends_on": [
        {
          "task_key": "model_training"
        }
      ],
      "notebook_task": {
        "notebook_path": "/Users/your-email@company.com/03_model_evaluation",
        "base_parameters": {
          "environment": "production"
        }
      },
      "existing_cluster_id": "your-cluster-id",
      "timeout_seconds": 1800
    }
  ],
  "schedule": {
    "quartz_cron_expression": "0 0 * * * ?",
    "timezone_id": "Australia/Sydney",
    "pause_status": "UNPAUSED"
  }
}

Deploying Jobs via Databricks CLI

Deploy your job using the Databricks CLI:

# Configure Databricks CLI
databricks configure --token

# Create job
job_id=$(databricks jobs create --json-file job_config.json | jq '.job_id')
echo "Created job with ID: $job_id"

# Run job
databricks jobs run-now --job-id $job_id

Monitoring Job Execution

Monitor job runs programmatically:

from databricks.sdk import WorkspaceClient
import time

client = WorkspaceClient()

# Get job details
job = client.jobs.get(job_id=12345)
logger.info(f"Job: {job.settings.name}")

# List recent runs
runs = client.jobs.list_runs(job_id=12345, limit=10)
for run in runs:
    logger.info(f"Run {run.run_id}: {run.state}")

# Get run details
run = client.jobs.get_run(run_id=67890)
logger.info(f"Run duration: {run.duration_ms}ms")
logger.info(f"Run state: {run.state}")

Step 7: Integrating with Microsoft Fabric for Reporting and Governance

Once your MLOps pipeline is operational, integrate results with Microsoft Fabric for reporting and governance.

Publishing Model Predictions to Fabric

Create a notebook that publishes predictions to a Fabric lakehouse:

import mlflow.pyfunc
from datetime import datetime

# Load production model
model = mlflow.pyfunc.load_model("models:/mlops_production_model/Production")

# Load new data for predictions
df_new = spark.sql("SELECT * FROM mlops_features WHERE date >= current_date() - 1")

# Make predictions
predictions_pdf = df_new.toPandas()
model_input = predictions_pdf.drop(columns=['target_column', 'id_column'])
predictions = model.predict(model_input)

# Add predictions to dataframe
predictions_pdf['prediction'] = predictions
predictions_pdf['prediction_timestamp'] = datetime.now()

# Convert back to Spark DataFrame
df_predictions = spark.createDataFrame(predictions_pdf)

# Write to Fabric lakehouse
lakehouse_path = "abfss://fabric-lakehouse@yourstorageaccount.dfs.core.windows.net/predictions/"
df_predictions.write.format("delta").mode("append").save(lakehouse_path)

logger.info(f"Predictions written to {lakehouse_path}")

Creating Power BI Dashboards

In Microsoft Fabric, create a Power BI report connecting to your predictions table. This enables stakeholders to monitor model performance and business outcomes in real-time.

Implementing Data Governance

Leverage Agile Insights governance frameworks to establish comprehensive data governance across your MLOps pipeline. Configure Azure Purview to track data lineage from raw ingestion through model predictions, ensuring compliance and auditability.

Step 8: Monitoring, Logging, and Troubleshooting

Production MLOps pipelines require robust monitoring and troubleshooting capabilities.

Implementing Comprehensive Logging

Enhance your notebooks with structured logging:

import json
from datetime import datetime

class PipelineLogger:
    def __init__(self, pipeline_name):
        self.pipeline_name = pipeline_name
        self.start_time = datetime.now()
        self.events = []
    
    def log_event(self, event_type, message, metadata=None):
        event = {
            "timestamp": datetime.now().isoformat(),
            "pipeline": self.pipeline_name,
            "event_type": event_type,
            "message": message,
            "metadata": metadata or {}
        }
        self.events.append(event)
        logger.info(json.dumps(event))
    
    def save_logs(self, path):
        log_df = spark.createDataFrame(self.events)
        log_df.write.format("delta").mode("append").save(path)

# Usage
pipeline_logger = PipelineLogger("data_preparation")
pipeline_logger.log_event("start", "Data preparation pipeline started")
pipeline_logger.log_event("data_load", f"Loaded {df.count()} records", {"source": data_path})
pipeline_logger.save_logs("abfss://logs@yourstorageaccount.dfs.core.windows.net/pipeline_logs/")

Monitoring Model Performance Drift

Implement model monitoring to detect performance degradation:

def check_prediction_drift(current_predictions, baseline_predictions, threshold=0.05):
    """
    Compare current prediction distribution with baseline
    """
    current_mean = current_predictions.mean()
    baseline_mean = baseline_predictions.mean()
    
    drift_percentage = abs(current_mean - baseline_mean) / baseline_mean
    
    if drift_percentage > threshold:
        logger.warning(f"Prediction drift detected: {drift_percentage:.2%}")
        return True
    return False

# Execute drift check
drift_detected = check_prediction_drift(current_preds, baseline_preds)

if drift_detected:
    logger.info("Triggering model retraining...")
    # Trigger retraining job

Common Troubleshooting Issues

Authentication Failures: Ensure your managed identity or service principal has appropriate permissions. Verify role assignments in Azure RBAC.

Data Connection Issues: Test connectivity to ADLS Gen2 using the Azure Databricks documentation on connecting to Azure Data Lake Storage Gen2. Verify network security groups and firewall rules.

Job Timeout Errors: Increase timeout values in job configuration. Optimise Spark queries using explain() to identify performance bottlenecks.

Memory Issues: Reduce partition size, increase cluster resources, or implement data sampling for development.

Model Registry Conflicts: Ensure only one process transitions models between stages to avoid race conditions.

Best Practices and Recommendations

Successful MLOps implementations require adherence to proven best practices developed through extensive industry experience.

Version Control and Reproducibility

Maintain version control for all pipeline code using Git. Store notebooks in a Git repository and use Databricks Git integration for version tracking. This ensures reproducibility and enables easy rollback if issues arise.

Testing and Validation

Implement comprehensive testing at each pipeline stage:

• Data quality tests: Validate schema, data types, and value ranges
• Model validation tests: Verify model performance meets acceptance criteria
• Integration tests: Confirm data flows correctly between pipeline stages
• End-to-end tests: Execute complete pipeline with test data

Cost Optimisation

Manage Azure and Databricks costs through:

• Cluster auto-termination: Set appropriate idle timeouts
• Spot instances: Use Azure Spot VMs for non-critical workloads
• Reserved instances: Purchase reserved capacity for predictable, long-running workloads
• Query optimisation: Monitor and optimise expensive queries

Security and Compliance

Implement security best practices:

• Encryption: Enable encryption at rest and in transit
• Access control: Use Azure RBAC and Databricks workspace-level permissions
• Audit logging: Enable comprehensive audit trails for compliance
• Secret management: Use Azure Key Vault for credential storage

For Australian enterprises, ensure compliance with the Australian Privacy Principles and relevant industry regulations such as APRA requirements for financial institutions.

Advanced Integration Scenarios

As your MLOps maturity increases, explore advanced integration patterns.

Real-time Inference with Azure Functions

Deploy real-time inference endpoints using Azure Functions and Databricks Model Serving:

# Create model serving endpoint
from databricks.sdk.service.serving import EndpointConfPair

endpoint_config = {
    "served_models": [
        {
            "model_name": "mlops_production_model",
            "model_version": "1",
            "workload_size": "Small",
            "scale_to_zero_enabled": True
        }
    ]
}

# Deploy endpoint
client.model_serving.create_endpoint(
    name="mlops_inference_endpoint",
    config=endpoint_config
)

Multi-Environment Deployments

Manage development, staging, and production environments:

def get_environment_config(environment):
    configs = {
        "dev": {
            "cluster_size": "small",
            "schedule_frequency": "hourly",
            "retention_days": 7
        },
        "staging": {
            "cluster_size": "medium",
            "schedule_frequency": "daily",
            "retention_days": 30
        },
