Workflow of Azure Machine Learning Service

The Azure Machine Learning Service workflow follows a three-step process to build, train, and deploy machine learning models. Let’s break it down:

Prerequisite: Workspace

Before starting, you need a Workspace. It is the central resource for managing all operations in Azure ML. The workspace:

• Holds compute targets used for training models.
• Stores logs, training metrics, outputs, and snapshots.
• Assists in selecting the best training model for deployment.
• Registers the trained models for further use.

1. Prepare Data

The first step involves collecting and processing data. This data is stored in datastores and accessed using datasets. Here's what each term means:

Datastores

Datastores store connection information for Azure storage services. They are attached to the workspace and referred to by name. Examples of supported services:

• Azure Data Lake
• Azure SQL Database
• Databricks File System
• Azure Blob Container

Datasets

A Dataset references data in data stores or public web URLs. It also keeps metadata copies. Azure supports two types of datasets:

• File Dataset: For unstructured data like images or documents.
• Tabular Dataset: For structured data like tables or spreadsheets.

2. Experiment

After preparing the data, you proceed to build, train, and test the model.

Model

A model is a piece of code that takes input and produces output. Developing a model involves:

• Selecting an algorithm.
• Providing data for training.
• Tuning hyperparameters to optimize performance.

Compute Targets

Compute targets are resources used to execute training scripts or host deployments. Types of computing targets include:

• Local Computer: Runs experiment submission code locally.
• Compute Cluster: A virtual cluster managed by Azure ML.
• Inference Cluster: A target for container-based deployments.
• Attached Compute: Includes services like Azure Databricks or Azure Data Analytics.

3. Deployment

After training and testing, the model is stored in the model registry and deployed as a service. The deployment process involves:

Image Creation

An image provides an environment for deploying the model independently. It includes the model, application, scripts, and dependencies. Types of images:

• FPGA Image: Used for deploying field-programmable gate arrays (FPGAs).
• Docker Image: Docker Image is used for deploying to resources like Azure Kubernetes Service or Azure Container Instances.

Service Deployment

The registered model is deployed as a service endpoint. The image is instantiated into a web service hosted on the cloud or an IoT module for integrated device deployment.

By following this workflow, you can create, train, and deploy efficient machine-learning models with Azure Machine Learning Service.

Core Components of Azure Machine Learning Services

If you're working with Azure Machine Learning Services, understanding its core components is crucial. These components help you seamlessly build, train, and deploy machine learning models. Let’s break them down so you can use them effectively.
