Adding machine learning to business processes has become a critical need for many companies who are trying to compete in the marketplace. This can be achieved through data factories which allow enterprises to dynamically build and deploy their own models, while keeping all of their existing code, tools and infrastructure intact.
The “azure data factory tutorial for beginners pdf” is a guide that can be used to get started with Azure Data Factory. The guide will teach you how to use the tool and how to create your first data pipeline.
Data is the new oil these days, but how does this influence a company moving to the cloud? or what happens when you move your data from several storage systems to the cloud, which is raw and disorganized? Thankfully, Microsoft Azure Data Factory has provided answers to these concerns.
Microsoft Azure Data Factory provides data integration and extract-transform-load (ETL) capabilities. These services enable you to create data pipelines, which are data-driven processes.
Sounds appealing? Let’s take a closer look at how fantastic Azure Data Factory is!
Prerequisites
Make sure you have an Azure subscription if you want to follow along with the step-by-step instruction. You can create a free Azure account if you don’t already have one.
What exactly is the Azure Data Factory?
Azure Data Factory is a cloud-based data integration tool that orchestrates data migration and transformation across various data repositories and computational resources.
Copying data to and from multiple Software-as-a-Service (SaaS) apps, on-premises data storage, and cloud data stores is one of the most fascinating tasks you can do with Azure Data Factory. Additionally, you may convert file types when copying.
After collecting the data, you work on the transformation side, which is termed Data Flows in the Integration Runtime (IR), and you take the ETL process seriously.
Creating a Data Factory in Azure
Because an introduction isn’t enough to grasp how Azure Data Factory works, you’ll build your own Azure Data Factory!
1. Launch your preferred web browser and go to the Azure Portal.
2. Select All services from the menu panel by clicking on the gateway menu icon in the top-left corner of the page. This allows you to see all of the services that are accessible to you.
All Services Are Available
3. Click on Analytics —> Data factories to view the overview page where you’ll see all of your previous data factories’ resources.
Data Factories Access
4. To create a new data factory resource, click Create to launch the assistant.
Creating an Azure Data Factory resource is the first step.
5. To add additional resources, choose the subscription and resource group. If you’d rather create a new resource group, click the Create new link, give it a name, and then click OK.

6. Now, add the following to the instance details:
- A area in which to develop the resource, usually the one nearest to you.
- A name for the resource that you like.
- To access the most recent features and enhancements, make sure the version is V2 (recommended by default).
- To continue the construction procedure, click the Next: Git configuration button.
Defining the Details of the Instance
7. Uncheck the option Configure Git later since you’re simply setting up the instance right now. To enter the Networking setup tab, click Next: Networking.

Git setup is being postponed.
8. To complete the configuration procedures, click Review + Create. The setting is set to Public endpoint by default, which is OK.
If you don’t want to utilize the Microsoft-managed key to encrypt your data, you’ll need to use the Advanced settings page. When you use tags to identify resources inside a project, for example, the Tags config tab is necessary. These tabs are not required for this demonstration.
Configuration of the Network
9. When all of the final validations pass, click the Create button to tell Azure to start building the Azure Data Factory instance.
Validating Data and Creating an Azure Data Factory
Creating a Storage Account in Azure Data Lake
You may now begin copying data using your Azure Data Factory. But first, build the Azure Data Lake Storage Account into which the Azure Data Factory will transfer data.
1. Hover your cursor over the Storage accounts button on the Azure Portal, and then click Create on the pop-up box that displays, as shown below. The website will then be sent to the “Storage Account” page.
Using the Azure Portal to create a Storage Account
2. Under the Basics tab, choose the same resource group and region you selected in the “Creating a Data Factory in Azure” section (step six).
Setting up a Storage Account Resource Group and Region
3. Give your storage account a distinctive name, such as demodfstorageaccount in our example. To keep expenses reasonable for these examples, choose Standard performance and alter redundancy to Locally-redundant storage (LRS). To go to the Advanced tab, click Next: Advanced.
Defining the Storage Account’s Name and Redundancy
4. On the Advanced tab, click the enable hierarchical namespace option under Data Lake Storage Gen2. When you choose this option, your storage account becomes a data lake rather than a conventional blob storage account.
To examine your storage account options, click Review + Create.
The Storage Account’s Hierarchical Namespace is enabled.
5. To complete the establishment of your Azure Data Lake Storage Account, click the Create button after the validation:
Validating and finalizing the creation of a storage account
Now that you have an active storage account, all you have to do is test it to see whether it works. In your Azure Data Lake Storage Account, transfer an example CSV file into a blob container named weather.
The National Centers for Environmental Information / National Oceanic and Atmospheric Administration provided the datasets for this demonstration (NCDD-NOAA). They also provide a free sample database for the Global Historical Climate Network’s daily summaries, which you may download as CSV files.
1. Go to the Azure Data Factory home page in your browser, then click Ingest to access the Copy Data Tool, where you’ll start a copy job.
Using the Copy Data Tool
2. Select the Built-in copy task option on the Properties tab to build a single pipeline. Click Next while keeping the default Run once now option selected for the task schedule.
When you choose Run once now, the copy job is started right after you put it up.
Choosing the Built-in Copy Option
3. Select HTTP from the Source type selection on the Source data store page to utilize the specified dataset for this example. To specify the source URL, click New connection.
Creating a New Source Data Store Connection
Set up the new connection by doing the following:
- Give the link a name (the definition of the data source)
- For this demonstration, copy and paste the following dataset URL into the Base URL field: https://www1.ncdc.noaa.gov/pub/data/cdo/samples/GHCND sample csv.csv
- Make Anonymous the authentication type.
- Leave the other defaults alone and click
